Photonic Technologies in 5G and Beyond
Room 1


  • Josep M. Fabrega (CTT, Spain)
  • Nikos Passas (Communication Networks Laboratory Dept. Of Informatics & Telecommunications University of Athens, Greece)

Motivation and Background:

Future 5G networks will give rise to a wide range of new services addressing the needs of multiple vertical markets (such as connected car, smart-factories, and others). The 5G end-to-end network infrastructure will have to support extreme requirements in terms of data rates, latency, reliability, energy efficiency, etc, that need an entire set of new technologies to support it.

For the evolution toward 5G mobile connectivity, it is envisioned that optical networking and photonics, as an enabling technology, will play a major role in supporting the service and network requirements, while reducing costs through the introduction of novel converged fibre and wireless technologies. One key target for the underlying optical network is to support the distribution and collection of millimetre-wave radio signals, enabling the greatest flexibility for the accommodation of the wireless network requirements, while reducing the cost of the wireless access points (i.e., remote radio heads/antenna units at cell-cites). Moreover, new multi-access edge computing (MEC) will play a significant role of offering new services closer to the end-user.

Photonic technologies and devices allow meeting the demanding capacity and latency demands for 5G in ways that scale well to highly densified network deployments with low footprint and energy consumption. This workshop will address the role and relevance of photonic technologies to 5G and any future development in mobile networks.

With this workshop we intend to attract expert speakers and audience who will discuss the relevant photonics technology solutions - those developed by 5G-PPP projects, Photonics-PPP projects, and others - and provide a complete coverage of the 5G-related topics for which optical networking and photonics can play a key role. Such topics will include but will not be limited to: optical access network solutions supporting fronthaul, photonics for mm-wave 5G, energy efficiency optimized 5G, converged optical-wireless system solutions, flexible aggregation/Metro networks and network orchestration.

5G in the Era of Connected Cars
Room 2


  • Roberto Riggio (Unit WiN - Wireless and Networked Systems, Italy)
  • François Fischer (ERTICO)
  • Jesus Alonso-Zarate (CTTC)

Motivation and Background:

Both the telecom and the automotive industries are going through profound transformations these day. The automotive industry is evolving towards a vision where cars are becoming autonomous and wirelessly connected to cooperate with each other for a safer and more efficient driving.

5G is regarded as the key technology that will empower this transition. For the success of such a revolution, it is necessary that both the telecom and the automotive industry cooperate together to shape the future by addressing all the challenges that connected, cooperative and autonomous mobility (CCAM) brings into the innovation arena.

The goal of this workshop is to bring both experts and projects from automotive and the mobile communications industries to discuss on the successful path towards CCAM services with the use of 5G technologies. The challenges and the approaches to reduce the uncertainties of a 5G deployment, in multi-country, multi-operator, multi-vendor, and multi-car-manufacturer scenarios, will be discussed and analysed. The validation via trials and the optimization of 5G technologies for CCAM services are additional topics of the workshop to pave the way for the preparation of commercial deployments.

TuA3: Tutorial 1 - Session 1go to top

Blockchain technology and smart contracts in 5G and beyond networks
Hamed Ahmadi, Irene Macaluso, Marco Ruffini, and Nima Afraz
Room 3

Blockchain is a revolutionary technology which has found its way to several domains outside of finance industry. The venture capitalist and software developer Marc Andreesen considers blockchain to be as important and revolutionary as the Internet. It is therefore reasonable to expect that aspects of this technology have the potential to underpin concepts, frameworks, regulations, and economics in the world of mobile communication and networking. Blockchain has numerous applications in these areas and will play a significant role in 5G and beyond networks. By enabling automatic and trusted transactions, smart contracts facilitate infrastructure and spectrum sharing among infrastructure providers, service providers, and virtual network operators. Blockchain also creates new business models for ephemeral networks and/or operator partnerships for better coverage and service. In a step forward, mobile operators can offer "Blockchain-as-a-service" ecosystem for content providers who could store their offerings throughout the mobile network and use the blockchain infrastructure for access control and monetization. In IoT networks blockchain can be applied to enhance privacy and security, data and identity management, and monetization of the service.

Since the first comm's related blockchain workshop in IEEE DySPAN2017, there has been a raise in the number of blockchain related publications in communication society, and there has been at least four workshops on this topic in major conferences which are showing the significant interest in this topic among members of communication society.

This tutorial will provide an introduction to blockchain technology and smart contracts to EUCNC participants. We will review its applications communication, networking and IoT in the first half of the tutorial. In the second half we will demonstrate hands-on Blockchain/smart contract programming which will be a unique opportunity especially for early career researchers and making our tutorial different from conventional conference tutorials.

Behind Wi-Fi's success story: Fundamentals, deciphering 802.11ax, and roadmap towards the next generation
David Lopez-Perez, Adrian Garcia-Rodriguez, and Lorenzo Galati Giordano
Room 4

Wireless-Fidelity (Wi-Fi) is among the greatest success stories of this new technology era, and its societal benefits are known to most of the world population. Since Wi-Fi has become an essential part of the home, and a key complementary technology for both enterprise and carrier networks, its importance is expected to continue growing beyond 2023, as the newly defined generation of more capable Wi-Fi products -Wi-Fi 6, based on the most recent Institute of Electric and Electronic Engineers (IEEE) 802.11ax specification- becomes widely available. The requirements of wireless data services, however, will continue to increase in many scenarios such as homes, enterprises and hotspots, beyond the capabilities of Wi-Fi 6. To meet such expectations, the Wi-Fi community is aiming high and has already initiated discussions on new IEEE 802.11 technical features for bands between 1 and 7.125 GHz. The creation and standardisation of the next generation of Wi-Fi technology beyond IEEE 802.11ax-referred to as Extremely High Throughput (EHT)-targets to increase peak throughput and ensure that Wi-Fi meets the requirements set by incoming applications, thereby maintaining-or even augmenting-its appeal to consumers.

The scope of the proposed tutorial is to provide the research community with

  1. a self-contained overview of Wi-Fi's fundamentals,
  2. a survey of the main technical features defined by the new 802.11ax standard, and
  3. fresh updates on the most recent outcomes and directions related to the next generation of Wi-Fi technology beyond 802.11ax directly from the IEEE 802.11 EHT standardization meetings.

EuCNC is the perfect occasion to provide a digestible summary about Wi-Fi's current technology status and prospective, since the first 802.11ax-compatible products are just reaching the market and the specific objectives and features of EHT are currently being shaped.

Empowering Transatlantic Platforms for Advance Wireless Research
Room 6


  • Serge Fdida (Sorbonne University & CNRS, France)
  • Abhimanyu (Manu) Gosain (IEEE SM, USA)
  • Arturo Azcorra (University Carlos III of Madrid, Spain)
  • Didier Bourse (Nokia, France)
  • Antonio de la Oliva (University Carlos III of Madrid, Spain)
  • Jaime Garcia-Reinoso (University Carlos III of Madrid, Spain)

Motivation and Background:

The European Commission has created the CSA EMPOWER in order to foster the collaboration between Europe and USA on Advance Wireless Platforms, which include ICT-17 End-to-End 5G platforms and NSF PAWR projects. The overarching aim of EMPOWER is to reinforce the cooperation between the EU and the US towards establishing a collaborative transatlantic community on the new connectivity frontiers beyond 5G with the ambition to accelerate the joint development of the associated advanced wireless platforms. EMPOWER follows and builds on the recurrent dialogue between the EU and the US regarding collaboration for Advanced Wireless Platforms as presented in the "Report from the EU/US Future Networks Workshop", dated November 11, 2017.

EMPOWER targets the creation of a joint EU-US advanced Wireless ecosystem for (i) bridging the relevant EU-US Wireless communities and stakeholders, such as scientific researchers, platform engineers, standardization experts, regulators, and product incubators; and (ii) developing a strategic EU-US collaboration agenda and supporting its execution ahead of worldwide competition for beyond 5G connectivity standards, based on common EU-US roadmaps spanning advances in scientific knowledge, platforms and testbeds, standards and regulations.

This workshop objective is to put in contact key persons on Europe and USA to start a track record of collaborations and to discuss posible joint activities and evolution of the wireless platforms at both sides of the Atlantic towards beyond 5G technologies. The workshop will be mainly driven by ICT-17 and NSF PAWR representatives, although projects planning to use the Wireless platforms, such as ICT-19 winning consortiums and projects with already established experience on collaboration with USA such as 5GinFire, will also be invited.

Participating Projects:

  • PAWR
  • 5G-EVE
  • 5G-VINNI


  1. Opening (45min)

    • Challenges for developing future test platforms to support research in digital infrastructures, Serge Fdida, Sorbonne Université, France
    • Introduction to PAWR, Abhimanyu Gosain, Technical Program Director of PAWR Office, Northeastern University College of Engineering
    • The EU/USA collaboration programme by Thyaga Nandagopal, NSF
    • EU/USA Collaboration, Bernard Barani, European Commission
  2. E2E System view (75 min)

    Round table focused on exploring E2E system level. The big question would be how to set-up an E2E open reference architecture. This might be a concern of mutual interest for Europe and USA as it goes beyond the wireless specific hardware components and target the issue related to the E2E architecture that should be encountered by most projects.

    We will discuss among others, the role of Open Source for experimentation, production and infrastructures:

    • Radio platforms: use of OAI/O-RAN or other platforms for the developing of the RAN in an open reference platform.
    • Core platforms: possible use of ONF/OMEC or other platforms for the development of the Core part of the open reference platform.
    • The need of an NFV open framework to provide a relevant test framework and toolset to perform tests.

From Cloud-ready to Cloud-native transformation
Room 8


Bessem Sayadi (Nokia Bell-Labs, France)

Motivation and Background:

The softwarization of the network is focused on the virtualization, decoupling the HW from the SW to lower the cost of network and service operation and to reduce the time to market for new services while introducing higher flexibility. In addition, virtualization of networking systems offers a multitude of benefits for telecommunication and datacenter operators by decoupling network functions from proprietary hardware as well as decoupling services from propriety service platforms.

In the same time, the cloud has disrupted the established order in many sectors. And the reason is simple. With it, companies have been able to reduce the investment in their internal data centers in favor of unlimited computing resources, available on demand and billed for use. From now on, the competitiveness of a company depends directly on its capacity to quickly realize new ideas. Start-ups understand this well, so they rely on native cloud approaches to disrupt traditional sectors. It becomes obvious that innovations should be made cloud-native for being successful where the functions are designed for a cloud environment rather than packaged up and deployed onto it.

Cloud-native is an approach to build and run applications that fully exploit the benefits of the cloud computing model. The Cloud-native approach is the way applications are created and deployed, not where they are executed. It includes things like services architectures, infrastructure as a code, automation, continuous integration/delivery pipelines, observability/monitoring tools, etc

A research ecosystem of horizontal and vertical R&D actions is being formed, which examines the transformation from cloud ready to cloud native in the telco world. A carrier-grade enhancement to the Telco cloud native platform is required to provide better-than-IT performance in par or better than what is possible with classical telco platforms. Features like five-nine reliability, stateless microservices, etc should be supported in the Telco cloud native. A fast virtualization and programmability across all networking domains: from core to edge and access, from wired/optical to wireless, cellular and also satellite, is also considered.

The workshop is not only about 5G technologies and their implementation - with, for instance, Cloud-RAN, functional split and resource management techniques in 5G - but also about the whole service-based technology relevant to 5G in the cloud-native transformation. A service-based technology, by definition, offers hardware and/or software resources provided as a service over a network.

This open workshop aims at reinforcing this European research ecosystem by strengthening the liaison between the participating projects, facilitating the exchange of ideas and helping each research group to take advantage of the results produced by other projects, improving focus of innovation and aligning towards common goals and milestones, thus maximizing the overall impact. The workshop will promote and stimulate the discussion about development of new research directions for building a stronger abstraction layer for the cloud, programmable infrastructure, cognitive management, flexible programmability of 5G networks services, managing application lifecycle in the cloud, etc

The workshop is endorsed by the Software Networks Working Group of the 5G-PPP ( and supported by participating projects and partners.

The participants will have the opportunity to exchange ideas, share hands-on experience and solutions and discuss research results. The workshop will aim in extending collaborations and paving common exploitation strategies. The structure of the workshop is based on invited presentation of 5G-PPP projects that operate on the same focus area, followed by breakout sessions on particular subjects allowing immediate interaction between the delegates and facilitating the exchange of expertise and best practices in the field.

The workshop will invite a Keynote to talk about the cloud transformation in Telco.

Network slicing has become a major networking paradigm in 5G networks to meet the diverse Quality of Service (QoS) requirements from different use cases. This paper presents the service-based control plane framework for QoSaware network slicing in the EU 5G PPP SliceNet project, and emphasises the QoS control mechanism for network slicing in the 5G backhaul network by leveraging software-defined data plane programmability. Both design and prototyping details are described. Experimental results have validated the proposed technical approach and implementation, and demonstrated the QoS performance gains in terms of latency and throughput.

Machine Learning for Artificially Intelligent Wireless Networks: Challenges and Opportunities
Walid Saad
Room 3

Next-generation wireless networks must support ultra-reliable, low-latency communication and intelligently manage a massive number of Internet of Things (IoT) devices in real- time, within a highly dynamic environment. This need for stringent communication quality-of-service (QoS) requirements as well as mobile edge and core intelligence can only be realized by integrating fundamental notions of artificial intelligence (AI) and machine learning across the wireless infrastructure and end-user devices. AI will play major roles in next-generation wireless networks ranging from data analytics to AI-powered self-organizing networks. To this end, the goal of this tutorial is to provide a holistic on the topic of machine learning for AI-powered wireless networks. In particular, we will first provide a comprehensive treatment of the fundamentals of machine learning and artificial neural networks, which are one of the most important pillars of machine learning. Then, we introduce a classification of the various types of neural networks that include feed-forward neural networks, recurrent neural networks, spiking neural networks, and deep neural networks. For each type, we provide an introduction on their basic components, their training processes, and their wireless use cases. Then, we overview a broad range of wireless applications that can make use of neural network designs. This range of applications includes ultra-reliable low latency communications (URLLC), wireless virtual reality, mobile edge caching, drone-based communications, Internet of Things, and vehicular networks.

For each application, we first outline the main rationale for applying machine learning while pinpointing illustrative scenarios. Then, we overview the challenges and opportunities brought forward by the use of neural networks in the specific wireless application. We complement this overview with a detailed example drawn from the state-of-the-art. Finally, we conclude by shedding light on the potential future works within each specific area and within the overall area of AI for wireless networks.

When Clouds meet 6G: the academic, industrial and standard perspective
Emilio Calvanese Strinati and Vincenzo Sciancalepore
Room 4

In 2020 the 5G Networks are expected to be operational and a global game changer from a technological, economic, societal and environmental perspective with very aggressive promised performance in terms of latency, reliability, energy efficiency, wireless broadband capacity, elasticity, and so on.

Nevertheless, experts claim that the next big step for cellular (and, generally speaking, wireless) networks is not the 5G realization but its next cloudification.

Virtualization and cloudification (or commonly dubbed as cloud computing) are often used interchangeably but they represent different concepts while involving a number of different technical challenges. Virtualization was introduced to consolidate physical servers running heterogeneous applications onto fewer (computing nodes) servers by placing the applications on so-called virtual machines (VMs) in a "hypervised" environment. This was the incipit for the Network Function Virtualization (NFV) paradigm to find a solid basis in communication networks supported by industry initiatives that aimed at saving CAPEX and OPEX while still claiming deployment flexibility and service agility. This brought up in the last years the network slicing concept that has completely revolutionized the networking perspective by abstracting and separating logical network behaviours from the underlying physical network resources thereby significantly impacting on the reduction of the operations expenditures which, in turn, drives the network operators to foster the programmability and automation of network facilities as well as to enable the evolution of a wider range of business services.

Conversely, Cloud computing refers to the delivery of shared on-demand computing resources through the public cloud (e.g., internet) or enterprise private cloud networks. This calls into question the need of cloudification, which translates into i) deploying communications software that has been rewritten and specifically designed for cloud environments, ii) enabling (low-latency) communication paths between cloud environments and iii) adding more flexibility and dynamicity (high reactiveness) on the orchestration process to successfully deliver agile services.

This tutorial focuses on the evolutionary flow of the network virtualization concept through several standard definition activities in the last decade. In particular, we shed light on the Network Function Virtualization pillars and the main difference with the upcoming cloudification phenomena of 5G-andbeyond networks. We analyse the state-of-the-art solutions proposed to realize the first example of cloudification, highlighting the main limitations of the current solutions and the real potentiality of advanced upcoming approaches. We present the interdependencies between 5G KPIs, 5G key enabling technologies and the three levels of cloud: Fog, Mobile Edge Cloud and the Central Cloud. In particular, for the Mobile Edge Cloud, we also provide the audience with a solid background and comprehensive description of the last 5 / 12

achievements of the ETSI MEC ISG group in terms of cloud computing features and interface descriptions. Finally, we point out the future research directions to embrace new open-source function/resource allocation procedures highlighting the viewpoint of few up-and-running H2020 projects.

5G networks emerge through leverage of unlicensed frequency spectra. A stunning eighty percent of today's mobile internet data traffic is off-loaded to Wi-Fi, which in turn is largely backhauled by copper or fiber access technologies. Successful fifth-generation networks will be based on a convergence of mobile and fixed technologies through this Wi-Fi hybrid of mobile and fixed access. This creates very important and technically exciting challenges for dynamic managing/optimizing space, time, and frequency dimensions for cost-effective delivery of all services with acceptable quality, across both Wi-Fi and 5G LTE. This talk will examine these trends and explore technological evolutionary steps and challenges that may well define the true emergency of high-speed internet connectivity reliably to all future internet data consumers.

A PN Code Design Based on Genetic Algorithm for Folding-Based GNSS Signal Acquisition
Keunhong Chae and Seokho Yoon (Sungkyunkwan University, Korea)
Although the acquisition of long pseudo-noise (PN) codes used in global navigation satellite systems can be faster by more folding, the number of folding is practically limited since the correlation property of the PN code could be more distorted for more folding, and consequently, the acquisition time could increase. In this paper, thus, we develop a PN code having a correlation property robust to the influence of the folding based on a genetic algorithm (GA), which allows us to use more folding for faster acquisition. Numerical results demonstrate that the proposed PN code achieves faster acquisition than the conventional PN codes.

Deep Learning to Forecast Energy Consumption in Smart Buildings Using Heterogeneous IoT Data Sources
Paulo Marques (Instituto Politecnico de Castelo Branco)
In the European Union, energy consumption in buildings represents about 40% of the total energy consumption. Accurate energy forecasting models is a key element of the building control and optimization process. The current research work is mainly focused on machine learning techniques with single time series data, i.e. using only historical energy consumption records. The research work presented in this paper combines data from heterogeneous IoT sensors and apply multivariate machine learning techniques for predictive building's energy consumption. The algorithms are tested and validate using a smart building IoT testbed deployed in an office environment. It is shown that using heterogeneous data streams available in smart buildings we can improve the forecasting capabilities of buildings energy consumption.
Flow Table Overflow Analysis with OpenFlow POX Controller
Ying Qian (East China Normal University, P.R. China); Kai Qian, Hossain Shahriar and Md Arabin Islam Talukder (Kennesaw State University, USA)
The emerging Software Defined Networking (SDN) architecture is a new network paradigm and its implementation, OpenFlow, decouples the control plane from the data plane and revolutionizes the current network computing. However, SDN/OpenFlow also introduces new vulnerability and security issues and there is a growing security challenge due to the SDN centralized controllers and OpenFlow switch's flow tables where the controllers need to closely work with. The limited flow table capacity of SDN/OpenFlow switches in memory is targeted by attacks. The flow table may be overflowed and the severe heavy packet-in/packet-out traffics between OFS and controller may paralyze the entire SDN. This paper analyzes the timeout impact on the flow table performance on Openflow POX controller in Mininet and proposes a new entry rule eviction algorithm to mitigate the SDN flow table overflow and improve the SDN performance.

Multi-Sensor Assisted Cooperative Beam Tracking for mmWave Vehicle-to-Vehicle Communication
Mattia Brambilla, Lorenzo Combi, Monica Nicoli, Sergio Savaresi and Umberto Spagnolini (Politecnico di Milano, Italy)
This paper presents an inertial measurement assisted technique for beam alignment and tracking in massive multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) communications based on millimeter waves (mmWave). Since directional communications in vehicular scenarios are severely hindered by beam pointing issues, a beam alignment procedure has to be periodically carried out to guarantee the communication reliability. When dealing with massive MIMO links, the beam sweeping approach is known to be time consuming and often unfeasible due to latency constraints. To speed up the process, we propose a method that exploits a-priori information on array dynamics provided by an inertial measurement unit on transceivers to assist the beam alignment procedure. Numerical results based on real measurements of on-transceiver accelerometers demonstrate a significant gain in terms of V2V communication throughput with respect to conventional beam alignment protocols.

In this poster we will specifically discuss a prototyping system focusing on the joint real-time experimentation of LTE and WiFi systems utilizing a single software-defined radio platform. This platform allows new experimentation results that will lead to a better understanding of the trade-offs when using different radio access technologies together as it would be the case in practical wireless network deployments.

Particles Traces Classification by a Spiking Neural Network Running on a Distributed Simulator
Rodolfo Rocco (University of Antwerp & Imec, Belgium)
Neural networks have been employed in the field of high energy physics both as online triggers and for offline data analysis. In the latter case, deep networks of artificial neurons are commonly employed, due to the great accuracy achieved in pattern recognition tasks. However, the simulation of these networks necessitates the computational power of GPU servers, thus incurring high operational costs for the hosting institution. To address this issue, we propose a new approach, in which the simulation is run by a network of peer-to-peer connected IoTs appliances. To illustrate this approach, a simulator for the Android platform was developed. A case study is presented, in which particles traces of two different kinds, produced either by muons or by electrons, must be classified. A network of spiking neurons, distributed among three smartphones, was trained with 100 pictures and was capable of correctly classifying 97% of the test dataset. The pictures were captured by the camera sensors of the same smartphones that simulated the network. This result shows how the proposed approach is successful in distributing the simulation of a machine learning task and its associated costs, while also showcasing the potential for further cost reduction by integration of the data acquisition and elaboration layers.

We investigate a downlink multicarrier distributed antenna system (DAS) for indoor industrial internet of things in order to meet ultra-reliable and low-latency requirement by exploiting space and frequency diversity. A DAS transmission strategy where a small number of selected distributed antenna panels are cyclically allocated every group of resources to transmit a codeword is proposed, and it is shown that its 1 %ile SINR performance to satisfy the required SINR for 10-7 of BLER within 1 ms of latency (including processing delay) is superior to typical multi-cell and co-located antenna systems.
LoRa Physical Layer Evaluation for Point-to-Point Links and Coverage Measurements in Diverse Environments
Gilles Callebaut, Guus Leenders, Stijn Crul and Chesney Buyle (KU Leuven, Belgium); Liesbet Van der Perre (KUL, Belgium)
Applications such as tracking livestock, monitoring the health of trees and environmental parameters, and other IoT services are emerging leveraging on Low Power Wide Area Networks. However, many of these applications do not require the complete network infrastructure of these technologies. By only employing the physical layer, point-to-point links can be set up, easing the installation and lowering the overall cost of these systems. In this paper, the advantages of creating such point-to-point LoRa connections over typical star networks is discussed. The physical layer is evaluated in three distinct environments, i.e., coastal, forest and urban. Our field measurements demonstrate coverage up to 1km with antennas at only 1.5m height in an urban scenario. In free Line-of-Sight this coverage is extended to 4km. The presented heatmap of the received signal strength and signal-to-noise ratio demonstrates the value of LoRa point-to-point connections in these environments. Based on the experimental results, an appropriate path loss model will be derived in future work.

  • Konstantinos Liolis (SES, Luxembourg)


5G is the first truly multi-technology communication system, where satellite role is being proven on the basis of its benefits and its integration in the overall network. The consensus and wider agreement on what satellite brings to achieve the 5G KPIs are: service ubiquity, service continuity, service scalability, broadcast (simultaneity) and security. Recent activities - with the active involvement of the satellite and terrestrial mobile industry stakeholders - develop already 5G features in satellite networks and include the necessary integration tests. Large-scale 5G testbeds are being developed to validate the end-to-end terrestrial-satellite 5G integrated system, network performance and demonstrate the seamless service delivery. To this end, several successful over-the-air demonstrations have taken place so far paving the way for the seamless satellite integration into 5G. In addition, several international standardization activities are ongoing to promote the satellite role into the 5G ecosystem. In this context, supported by the ongoing relevant EU 5GPPP projects (SaT5G, 5G-VINNI, 5GENESIS) and ESA ARTES projects (Satellite for 5G - S45G, SATis5, EdgeSAT, etc.), this Special Session builds upon the success of the series of past relevant events and aims to showcase that satellite integration into 5G is in fact getting closer to reality. In particular, this Special Session will:

  • Highlight the experiences, results and lessons learnt from successful over-the-air demonstrations towards the seamless satellite integration into 5G;
  • Update on the status of 5G experimentation facilities optimising the integrated satellite-terrestrial 5G network architecture and exploiting edge network connectivity concepts;
  • Promote the emergence of innovative services and new business models making use of 5G networks integrating satellite in response to the various 5G verticals requirements;
  • Foster cross-industry cooperation opportunities between terrestrial mobile and satellite industry in the context of 5G ecosystem;
  • Provide insights into the status of standardization activities for satellite integration into 5G.

Optimal Sequence and SINR for Desired User in Asynchronous CDMA System
Hirofumi Tsuda (Kyoto University & Graduate School of Informatics, Japan)
We consider asynchronous CDMA systems in no-fading environments and focus on a certain user. This certain user is called a desired user in this paper. In such a situation, an optimal sequence, maximum Signal-to-Interference plus Noise Ratio (SINR) and the maximum capacity for a desired user are derived with other spreading sequences being given and fixed. In addition, the optimal sequence and SINR for a desired user are written in terms of the minimum eigenvalue and the corresponding eigenvector of a matrix, respectively. Since it is not straightforward to obtain an explicit form of the maximum SINR, we evaluate SINR and obtain the lower and upper bounds of the maximum SINR. From these bounds, the maximum SINR may get larger as the quantities written in terms of quadratic forms of other spreading sequences decreases.
An Unnoticed Property in QC-LDPC Codes to Find the Message from the Codeword in Non-systematic Codes

The generator matrix of quasi-cyclic low-density parity-check (QC-LDPC) codes is not, in general, in systematic form. Therefore, finding the message corresponding to a detected codeword at the receiver is not as straightforward as it is in the case of systematic codes. In this paper, we propose two methods for finding the message from the codeword in a QC-LDPC code. The first method is a general scheme which views the problem as a set of linear equations. This method is hardly realizable in hardware due to complexity. The second method is an alternative scheme which makes use of the particular structure in generator matrices of QC-LDPC codes in order to find the message from a non-systematic codeword. We examine a large class of non-systematic Latin-square QC-LDPC codes and one of the IEEE 802.16e standard QC-LDPC codes, and show that they have the required structure to be usable by the algorithm. The latter method is realizable in hardware and can be implemented with a digital circuit consisting of XOR gates.
Packet Recovery Latency of a Rate-less Polar Code in Low Power Wide Area Networks
Yi Yu (ISEP, France); Lina Mroueh (Institut Supérieur d'Electronique de Paris, France); Guillaume Vivier (Sequans, France); Michel Terré (CNAM, France)
In this paper, we consider a Low Power Wide Area Networks (LPWAN) operating either in a licensed-exempt band. In order to enhance the receiver sensitivity, low complexity repetition schemes that benefit from the time-varying channel condition are widely used. In this case, successful data recovery requires a significant channel variation from a bad to a good state depending on the data rate. This induces a relatively high decoding latency especially for slow time-varying channel. The main objective of this paper is to reduce the packet recovery latency by exploiting multiple channel states defined with respect to various transmission data rates, that are enabled by a rate-less polar code. We characterize the good channel sequence state of this code, and evaluate its latency performance in a slow and fast-time varying context.
5G New Radio over Satellite Links: Synchronization Block Processing
Harri Saarnisaari (University of Oulu, Finland); Jean-Michel Houssin and Thibault Deleu (Thales Alenia Space, France)
Harmonization of terrestrial standards such that they would support satellite elements would offer several benefits. Such work has started at 3GPP relating to 5G new radio (NR). Downlink initial access is one of the topics that has to be evaluated in this respect among many others. This paper studies detection of the synchronization signals included in the synchronization (SS) block of the 5G NR signal in satellite channels that have large, up to 720 kHz, Doppler frequency shift at 30 GHz carrier frequency. Furthermore, the reception of system information data in the SS block is considered. It is shown that using dedicated large frequency shift aware detectors it is possible to meet the 5G NR requirements in the detection part. However, the data part cannot be reliably received using one-shot reception at low signal-to-noise values. Some alternative solutions are considered and evaluated though some of them require changes to the standard in order to be efficient.
Integrating Sparse Code Multiple Access with Circularly Pulse-Shaped OFDM Waveform for 5G and the Factories of the Future
Yenming Huang (National Taiwan University & Graduate Institute of Communication Engineering, Taiwan); Rueibin Yang and Borching Su (National Taiwan University, Taiwan)
Circularly pulse-shaped orthogonal frequency division multiplexing (CPS-OFDM) waveform integrated with sparse code multiple access (SCMA) is proposed for 5G and the Factories of the Future (FoF). The physical-layer properties of low out-of-subband emission (OSBE) and low peak-to-average power ratio (PAPR) claimed by CPS-OFDM can be well preserved with the top-down codebook used in SCMA. Simulation results also reveal that the proposed transmission method possesses higher detection reliability and spectral efficiency than those of other existing SCMA-OFDM-based schemes in practical FoF environment.

The advent of 5G promises to unleash highly pervasive network coverage and density, increased data rate and capacity, optimized instantiation of virtualized resources in a multi-tenant and multi-service network capable of fulfilling the stringent requirements of various heterogeneous vertical applications. Network slicing is widely recognized as one of the key enablers of such 5G to allow multiple isolated virtual networks to be created on the a single shared physical network infrastructure. In this work, we present a survey of various approaches for slicing, we review the management and orchestration tools available to implement network slicing, and describe the Network Slicing architecture designed for the 5GCity project. Our network slicing framework embraces creation of slices of various network elements such as compute nodes, physical networks, radio parts and network edge resources. The slicing concept described in this paper is being evaluated in three live city pilots (Barcelona-ES, Lucca-IT, Bristol-UK) which represent the trial environment for the 5G use cases of the 5GCity project.

5G networks will pose complex network management challenges due to the variety of vertical services they will need to serve and the diversity of underlying infrastructure. The service orchestration functionality is fundamental to enable fulfilling the requirements of the former while efficiently using the infrastructure resources. This paper details the 5G-TRANSFORMER service orchestrator implementation and operation. It also evaluates and profiles service creation time showing how the automation offered by the platform allows reducing it from hours to minutes. It also shows that the most time-consuming steps correspond to the deployment of the virtual network functions and post-deployment configuration, which consume one order of magnitude more time than the rest of steps (e.g., network creation, port creation).

The Fifth Generation (5G) networks leverage softwarisation and virtualisation as cornerstones to build cost-effective and flexible infrastructures and services. Meanwhile, advanced orchestrator is entailed to manage and orchestrate the resources and services at various levels of infrastructures, including the physical layer, virtualisation layer, service layer etc. The challenges become more evident when the multiple business roles, enabled by the various levels of operations in this new business model paradigm, are taken into account in an integrated operational environment. This paper proposes a new layered, inter-business vertical orchestration architecture to address the highlighted challenges in softwarised and virtualised 5G networks. The architecture distinguishes not only the infrastructure levels but also the business roles, both in an integrated framework with interactions among them specified. It is noted that the proposed vertical orchestration architecture is compatible with network slice orchestration in 5G networks. The proposed orchestration framework is prototyped in a testbed with realistic 5G infrastructures, and its performance is empirically evaluated focusing on the service creation time 5G Key Performance Indicator (KPI).

This paper describes how the novel Next Generation Platform-as-a-Service (NGPaaS) framework can facilitate major benefits for Network Operators and Vertical Service Providers (VSPs) who wish to leverage Virtual Network Functions-as-a-Service (VNFaaS) capabilities. Network Operators can benefit by providing an on-demand PaaS with required features for the VSPs, thus generating new revenue streams but with low operational overhead due to the high degree of automation. VSPs can benefit from the PaaS-oriented approach, by being able to flexibly on-board new VNF types and "value-added" service capabilities like monitoring, healing and profiling, to deliver customized service blueprints to meet the needs of their end customers. The paper outlines the design of an early prototype, built on the Open-CORD platform and using industry-standard Virtualised Network Functions (VNFs).
vFPGAmanager: A Hardware-Software Framework for Optimal FPGA Resources Exploitation in Network Function Virtualization
Spyros Chiotakis (Virtual Open Systems, France); Sébastien Pinneterre and Michele Paolino (Virtual Open Systems SAS, France)
The emergence of network function virtualization (NFV) has turned dedicated hardware devices (routers, firewalls, wide area network accelerators) to virtual machines (VMs). However, the costs to run these as virtualized network functions (VNF) in general purpose hardware is slower performance and higher energy costs. Field programmable gate arrays (FPGAs) are a promising solution to offset these performance and energy costs thanks to their reconfigurable fabric and acceleration capabilities. To offer quick access, high-throughput and sustain high-speed data streams many FPGA boards are bundled with the PCIe protocol. This protocol uses the Single Root I/O Virtualization (SR-IOV) standard to provide VMs direct access to the FPGA card and achieve close to native performance through hardware implemented virtual functions (VF). Thanks to SR-IOV VFs, VNFs can benefit of a simplified hardware exposure to the software. Despite that, SR-IOV has a strong impact on the resources usage flexibility and efficiency. As for flexibility, the number of VFs available is limited and this restricts the number of VNFs that can be accelerated. In fact, the VNFs that remain without a VF cannot take advantage of FPGA acceleration capabilities, even if there are FPGA resources available. In addition, if the VNFs that are attached to VFs underutilize the FPGA resource then the remaining VNFs that might be in greater need of acceleration are prevented from accessing the FPGA. In this paper, we present FPGA Virtualization Manager (vF- PGAmanager), an SR-IOV based framework that allows multiple VNFs to access different FPGA accelerators in a PCIe card through a single VF. vFPGAmanager is connected to these VFs through a multi-channel PCIe DMA and is responsible for routing packets to the corresponding accelerators. By using a multi- channel PCIe DMA vFPGAmanager is responsible for routing packets between VNFs and FPGA accelerators. Our key ideas are to containerize the VNFs inside a VM and provide them access to different accelerators in the FPGA fabric through the DMA and load balance the VF resource optimally. The results show a penalty of 30% in the worst case in throughput performance where two VNFs request acceleration at the same time from the FPGA using the same VF. For the best case scenario, when the VNFs don't concurrently request FPGA acceleration, we have close to native performance.

The paper proposes and experimentally investigates the performance of the duobinary transmission technique for a highly bandlimited VLC system. By adding a controlled amount of inter-symbol interference (ISI) into the transmit pulse shaping filters, the supported data rate can be doubled requiring the same signal bandwidth. To gain full insight into duobinary signalling, the so-called modified binary scheme is also tested. The bit error rate (BER) performance of both systems is measured for a range of data rates, before comparison with the ideal binary and traditional on-off keying non-return to zero (OOK-NRZ) formats across the same physical link. We show the duobinary system can support higher bit rates and lower BER than OOK-NRZ while requiring half the bandwidth of the binary scheme.

Terahertz band has gained enormous interest recently due to its wide bandwidth availability, and the data rate is reaching $100$ Gbps are nowadays achievable. The current advancement in Terahertz technology is aiming to achieve the data rate up to 1 Terabit per second. However, the unique band characteristics introduce some issues related to the propagation channel like high path and absorption loss which increases with distance. Such limitations at one hand can limit the coverage and throughput. But, on the other hand, suits indoor environment such as data center, a data center geometry is used in this paper to design and model a network of THz nodes placed on the top of the data center racks, to increase network connectivity, THz reflectors are positioned on ceiling and walls. Through simulations, we show that it is possible to reduce the average number of interferers in the system and minimize bit error probability by using specific waveforms and planar antenna array with active variable elements.

The following paper compares, from a techno-economic point of view, the deployment of different broadband access technologies in four types of geographical areas which differ in terms of surface, and number of households. The study concerns urban and rural areas and the rural areas are divided in homogeneous and heterogeneous scenarios to be able to come up with more realistic conclusions. In order to cover realistic scenarios, four engineering models have been considered: two of them based on Gigabit Passive Optical Network based (GPON-based): in the first one, poles and ducts are available and can be used to support fibre, whereas in the second one, civil engineering is required. The two other models are based on Fixed Wireless Access (FWA) provided respectively by 4G and 5G infrastructures. A tool has been designed to asses the profitability of these deployments in terms of payback period over a long period of time, taking explicitly into account investment costs, operational costs and take-up rates. The final results showcase the match between the topology and the deployment model, in regard to the network costs. A full data set is provided, which makes the study adaptable and replicable. The paper then provides some answers to the following question: which technology is better suited to provide broadband access in a specific area type?

A scalable cost-effective solution for high service availability featuring low latency CDN caching is making other MAN data centers at a distance within the latency budget backup other data centers of usually lesser reliability. Given the low latency target of caching, the optical layer is the preferred option to interconnect caches. However, carrying the backup traffic from one data center (DC) to another with a permanent optical circuit based on Fixed Transceivers (FT) features low utilization and no statistical multiplexing gain on the path, which makes the backup network resources costly. In this paper we compare several approaches to implement this scenario with dynamic circuits, considering both inter-cache and backup traffic with FTs featuring both permanent and switched optical circuits, and with the Tb/s sliceable bandwidth-variable transceivers (S-BVT) developed in the EU project PASSION. As we show, S-BVTs can be key devices to improve backup-network scalability in terms of IT resources and transceivers, thanks to their capability to adapt to the actual traffic demand and to obtain multiplexing gains at the optical layer.
Adaptive Unipolar MIMO-OFDM for Visible Light Communications
Mohamed Al-Nahhal (Ozyegin University, Turkey); Ertugrul Basar (Koc University, Turkey); Murat Uysal (Ozyegin University, Turkey)
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for U-OFDM systems by applying adaptive transmission over realistic VLC links. This adaptive transmission includes switching among a number of multiple-input multiple-output (MIMO) modes combined with appropriate modulation size selection. The considered MIMO modes are repetition coding, spatial modulation, and spatial multiplexing, where each mode supports different modulation sizes. The selection of the corresponding MIMO mode and its modulation size is based on the received signal-to-noise ratio and target bit error rate. The proposed U-OFDM system is applied over different VLC MIMO setups with realistic channel models for 8 × 8, 4 × 4 and 2 × 2 MIMO systems. Our simulation results show that the proposed adaptive system provides a significant spectral efficiency improvement over stand-alone U-OFDM MIMO modes/setups.

The vision of cooperative, connected and automated mobility (CCAM) along Europe can only be realized when harmonized solutions that support cross-border traffic exist. The possibility of providing CCAM services along different countries when vehicles traverse various national borders has a huge innovative business potential. However, the seamless provision of connectivity and the uninterrupted delivery of realtime services along borders also pose technical challenges which 5G technologies promise to solve. The situation is particularly challenging given the multi-country, multi-operator, multi-telco vendor, multi-car-manufacturer, and cross-generation scenario of any cross-border layout. Motivated by this, the 5GCroCo project, with a total budget of 17 million euro and partially funded by the European Commission, aims at validating 5G technologies in the Metz-Merzig-Luxembourg cross-border corridor, traversing the borders between France, Germany and Luxembourg. 5GCroCo validation will focus on three use cases: 1) tele-operated driving, 2) high definition map generation and distribution for automated vehicles, and 3) Anticipated Cooperative Collision Avoidance. The results will help reduce the uncertainties associated with eV2X communications across borders in Europe in preparation of commercial 5G deployment.

The next generation mobile technology, 5G, together with edge computing will create new opportunities for developing novel road safety services for supporting connected and automated driving. This paper studies the feasibility and benefits of localized mobile network edge applications for supporting vehicles in diverse conditions. In our network centric approach, the vehicle sensor data processing required by the road safety services is installed into the mobile network edge instead of the vehicles carrying the sensors. This may be necessary due to vehicle processing capacity limitations or business reasons. Specifically, we focus on a LiDAR data based obstacle warning case, in which vehicles receive obstacle warnings from the mobile network edge. We conduct experimental evaluation both in a real vehicle testbed environment and in a laboratory setting. As a result, we obtain first insights on the feasibility of the overall solution and further enhancements needed.
Monitoring Resilience in a Rook-managed Containerized Cloud Storage System
Louis Baumann and Stefan Benz (Abraxas, Switzerland); Leonardo Militano and Thomas Michael Bohnert (Zurich University of Applied Sciences, Switzerland)
Distributed cloud storage solutions are currently gaining high momentum in industry and academia. The enterprise data volume growth and the recent tendency to move as much as possible data to the cloud is strongly stimulating the storage market growth. In this context, and as a main requirement for cloud native applications, it is of utmost importance to guarantee resilience of the deployed applications and the infrastructure. Indeed, with failures frequently occurring, a storage system should quickly recover to guarantee service availability. In this paper, we focus on containerized cloud storage, proposing a resilience monitoring solution for the recently developed Rook storage operator. While, Rook brings storage systems into a cloud-native container platform, in this paper we design an additional module to monitor and evaluate the resilience of the Rook-based system. Our proposed module is validated in a production environment, with software components generating a constant load and a controlled removal of system elements to evaluate the self-healing capability of the storage system. Failure recovery time revealed to be 41 and 142 seconds on average for a 32GB and a 215GB object storage device respectively.

Just before the commercial roll-out of European 5G networks, 5G trials in realistic environments have been recently initiated all around Europe, as part of the Phase 3 projects of 5GPPP H2020 program [1]. The goal is to showcase 5G's capabilities and to convince stakeholders about its value-adding business potential. The approach is to offer advanced 5G connectivity to real vertical industries and showcase how it enables them to overcome existing 4G network limitation and other long-standing issues. The 5G EVE H2020 5GPPP project [2] offers cutting-edge 5G end-to-end facilities (in 4 countries) to diversified vertical industry experimenters. The objective is to understand the needs of prominent industries across Europe and to offer tailor-made 5G experience to each and every one of them. This paper contributes to the understanding of vertical services needs, by offering a thorough and concise vertical requirements analysis methodology, including an examination of the 4G limitations. It also provides real-life values for the targeted KPIs of 3 vertical sectors namely Smart Industry (4.0), Smart Cities / Health and Smart Energy, while assisting market roll-out by prioritizing their connectivity needs.

This paper introduces the practical measurements regarding delay, jitter and throughput committed in conjunction with the remote control demonstrator development using 5G test network. The results gathered from the extensive evaluation using the 5G, LTE-A and WLAN wireless technologies not only strengthen the remote control demonstrator test bed, but also validate the improved 5G performance suitable for remote operations. The measurements using the first prototype of 5G radio technology enable as low as 1 ms radio link delay reducing the delay significantly compared to current WLAN and LTE-A technologies. During the ongoing 5G standardization, automation and remote control systems are one of the use cases due to low delay networking in 5G, which enable a wide range of possibilities to operate from a distance. For better understanding and planning the transition from current wireless network technologies to 5G, it is essential to identify the current performance of the existing wireless network technologies especially in comparison to network delay that is a crucial factor in remote control scenarios.

While the wireless world is moving towards the 5G era and many technological advances have been proposed, there seem to be significant limitations in the capability to efficiently and flexibly handle the massive amount of QoS/QoE-oriented data that will be exchanged in a future Big-Data-driven society along with the super-high data rate and almost zero latency requirements.

Thus, wireless Tbit/s communications and the supporting backhaul network infrastructure are expected to become the main technology trend within the next ten years and beyond. Terahertz (THz) transmission as a wireless backhaul extension of the optical fibre is an important building block to close this gap and guarantee high-speed internet access everywhere beyond 5G. Together with extraordinary promises, THz communication brings unique and novel challenges that require rethinking classic communications and networking mechanisms. Motivated by the potential of THz technologies to transform the future of ICT, this Special Session aspires to reveal and discuss the critical technology gaps as well as the appropriate enablers, in terms of baseband processing RF frontend, channel models and waveforms, signals and coding, beam-patterns and medium access schemes. This special session brings together experts in information and coding theory, in advanced hardware design and ASIC integration and wireless access technologies and algorithms to present the main implementation challenges to be faced and to describe specific designs, algorithms and architectures, designed towards Terabit/s throughputs.

Channel Coding for Tbit/s Communications: An Implementation Centric View
Norbert Wehn (University of Kaiserslautern, Germany)
The continuous demands for higher throughput, higher spectral efficiency, lower latencies, lower power and large scalability in communication systems impose large challenges on the baseband signal processing. In the future, throughput requirements far beyond 100 Gbit/s are expected, which is much higher than the tens of Gbit/s targeted in the 5G standardization. At the same time, advances in silicon technology due to shrinking feature sizes and increased performance parameters alone will not provide the necessary gain, especially in energy efficiency for wireless transceivers, which have tightly constrained power and energy budgets. In this talk we will focus on channel coding, which is a major source of complexity in digital baseband processing. We will give an overview and first results of the EPIC project, funded by European Union's Horizon 2020 research and innovation program, that aims to develop a new generation of Forward-Error-Correction codes in a manner that will serve as a fundamental enabler of practicable beyond 5G wireless Tb/s solutions. We will highlight implementation challenges for the most advanced channel coding techniques, i.e. Turbo codes, Low Density Parity Check (LDPC) codes and Polar codes and present decoder architectures for all three code classes that are designed for highest throughput.
Regulatory Aspects of THz Communications and Related Activities Towards WRC 2019
Thomas Kuerner (Technische Universitaet Braunschweig)
A pre-requisite for the global use of THz communications is the availability of spectrum. While the current version of the Radio Regulations does not include any allocation of spectrum beyond 275 GHz to any service, footnote 5.565 of the radio regulations defines the protection of passive services in these frequency bands. The use of ultra-large bandwidths of several tens of GHz for THz communications is only possible when spectrum can be shared between THz communications and the passive service. In the framework of the World Radio Conference (WRC) 2019, the corresponding sharing studies are ongoing. In this contribution, the regulatory boundary conditions, first results from sharing studies and the next steps are described.

Modeling and Link Budget Estimation of Directional mmWave Outdoor Environment for 5G
Sheeba Kumari M (VTU, Bangalore, India); Sudarshan Rao (BigSolv Labs Pvt Ltd Bangalore, India); Navin Kumar (Amrita University & School of Engineering, India)
Narrow pencil-beam forming is a key enabling technique for millimeter wave (mmWave) systems to achieve high link quality. Employing highly directional narrow beam antennas will deliver unique requirements on mmWave channel modeling. In this paper, we propose a low complexity mmWave channel model to analyze the performance of line of sight (LOS) and non-line of sight (NLOS) directional outdoor links in several reference cases. This ray tracing based model integrates the antenna geometry of a highly directional antenna in 3D plane. The effects of specific attenuation and foliage losses are also incorporated to enhance the model accuracy. Simulation results show that the deterministic channel fading gain varies as a function of antenna location, height and beamwidth in addition to its variations against distance. The model is validated against standard channel models and measurements, at frequencies and deployment scenarios reported in the literature. Furthermore, link budget estimates and signal-to-noise ratio (SNR) results are evaluated. The proposed model, unlike many state-of-the-art models, describes the channel for any mmWave frequency, antenna beamwidth, transmitter/receiver height and location by just changing these parameters in the simulator. The study highlights the need to integrate directional antenna effects and deployment parameters in the channel model to have accurate performance predictions.
Transmission Through Large Intelligent Surfaces: A New Frontier in Wireless Communications
Ertugrul Basar (Koc University, Turkey)
In this paper, transmission through large intelligent surfaces (LIS) that intentionally modify the phases of incident waves to improve the signal quality at the receiver, is put forward as a promising candidate for future wireless communication systems and standards. For the considered LIS-assisted system, a general mathematical framework is presented for the calculation of symbol error probability (SEP) by deriving the distribution of the received signal-to-noise ratio (SNR). Next, the new concept of using the LIS itself as an access point (AP) is proposed. Extensive computer simulation results are provided to assess the potential of LIS-based transmission, in which the LIS acts either as an intelligent reflector or an AP with or without the knowledge of channel phases. Our findings reveal that LIS-based communications can become a game-changing paradigm for future wireless systems.
The Effect of Rough Surface Statistics on Diffuse Scattering at Terahertz Frequencies
Mai Alissa (University Duisburg Essen, Germany); Theo Kreul (University of Duisburg-Essen, Germany); Thomas Kaiser (Universität Duisburg-Essen, Germany)
In Terahertz region, the diffuse scattering phenomenon by rough surfaces has a remarkable effect of non-line of sight (NLOS) channel propagation. Several parameters contribute to form a specific distribution of the scattered rays, and the angular distribution of the scattered field varies depending on the surface roughness parameters. Yet, a clear understanding of how these parameters adjust the scattered field distribution is still missing. In this work, we investigate the scattering properties of indoor materials at Terahertz band. This is done via full-wave simulation of the diffused scattering by rough samples varies in their roughness characteristics. Then, the role of each statistical parameter is investigated separately. It was proven that both the surface correlation function and the correlation length have an influence on the far field scattered energy. While the height standard deviation has a direct effect on the specular part, the correlation length seems to affect the power distribution out of the specular direction. The longer the correlation length, the more energy is accumulated closer to the specular direction. The resulting angular distribution can be then applied for obtaining more accurate NLOS channel predictions.

Thomä (Ilmenau University of Technology, Germany)
In the present paper we introduce the results of simultaneous multi-band ultra-wideband measurements at 6.75, 30, and 60 GHz in a street canyon scenario under LOS in Germany. This is the first part of a street canyon measurements series using the same channel sounder in different parts of the world. The aim of these measurements is to analyse and compare the propagation characteristics with multi-band channel modelling in view. We show that from the propagation perspective, mm-waves offer very similar opportunities than the well known and exploited sub-6 GHz bands.

The concept of network slicing is considered as a key part in the development of 5G. Network slicing is the means to logically isolate network capabilities in order to make each slice responsible for specific network requirement. In the same light, the micro-operator concept has emerged for local deployment of 5G for vertical specific service delivery. Even though micro-operator networks are expected to be deployed using 5G, most research on network slicing has been directed towards the description on the traditional Mobile Network Operator's (MNO) networks with little emphasis on slicing in local 5G networks deployed by different stakeholders. In order to achieve slicing in a micro-operator network, it is of vital importance to understand the different deployment scenarios that can exist and how slicing can be realized for each of these deployments. In this paper, the micro-operator networks described include closed, open and mixed network, and for each of these network, different deployment scenarios are established. The paper further proposes approaches for the configuration of Network Slice Instances (NSIs) using the Network Slice Subnet Instances (NSSIs) and other Network Functions (NFs) in a micro-operator network while considering the different deployments. The results highlight the possible deployment scenarios that can be established in a micro-operator network and how network slicing can be efficiently realized for the various local deployments.

5G intends to use network slicing to support multiple vertical industries. The dynamic resource sharing and diverse customer requirements bring new challenges towards service assurance (SA), such as automation and customer-centric. As a response to these challenges, this paper proposes a hierarchical, modular, distributed, and scalable SA architecture. This paper highlights an important key feature SA coordination which is facilitated by three new SA functions, SA interpretation, SA policy management, and data fabric. Three closed-loops are introduced to coordinate and realize automation of service management. Challenges associated with realizing SA are briefly discussed and will be addressed by leveraging the 5G infrastructure developed within the H2020-ICT-17 project 5G-VINNI.

Network slicing is an important concept for telecommunication companies for optimizing their infrastructure and providing customized services. In order to deploy them, it is necessary to fully understand the customer requirements. The Communication Service Management Function (CSMF) is an entity that has this task, acting as a gateway to translate these requirements towards the network slicing ecosystem. Even though we know the tasks for the CSMF, we find there is no complete definition of its internal elements and interactions. Our contribution is twofold: (i) we provide a comparison with current implementations and their weaknesses; and (ii) we propose a complete model of the CSMF, its internal structure and its interaction with other elements of the network slicing infrastructure.
Deploying Smart City Components for 5G Network Slicing
Bogdan Rusti (Orange Romania, Romania)
The integration requirements between digital systems acting as enablers for vertical industries services and network layers represents a big challenge for multitenant vertical slice deployment initiatives over 5G infrastructure. Several concepts were developed, among them Smart City 5G-ready application based on cloud-native/microservice principles that proposes a separation between the orchestration of the 5G applications and the network services that support them. In this paper we are presenting the deployment phases of Smart City demonstrator focusing mainly on its first phase which covers the test bed deployment and the on-boarding process of application components. It is an advanced stage in the evolution of the project from the theoretical concept proposal [1], followed by the design and development phase as a collaboration between two 5G-PPP EU projects MATILDA and SliceNet [2] toward its completion as an automated solution for development, deployment and management of a Smart City 5G cloud-native application slice over the virtualized infrastructure. The target is to create and implement an end-to-end operational service framework starting from design and development to end to end orchestration over a 5G infrastructure through a One-Stop API assuring the end-to-end management, control and orchestration of the slice.

To address the limitations of legacy PS solutions, as narrow bandwidth, high deployment cost and poor flexibility, the 5G cellular systems have been proposed. 5G ESSENCE project builds on the reference 5G PPP architecture and enhance it with a cloud-enabled small cell infrastructure, proposing a fully distributed orchestration architecture leveraging multi-access technologies. Furthermore, SDN and NFV are exploited to create flexible slices for dedicated mission critical public safety applications. This is shown by describing as the mission critical push-to-talk and group communications services have been implemented in a real testbed.

Optimising Layered Video Content Delivery Based on Satellite and Terrestrial Integrated 5G Networks
Satish Kumar, Ning Wang, Chang Ge and Barry Evans (University of Surrey, United Kingdom (Great Britain))
Multimedia delivery over satellite network may be considered as a promising service in the emerging 5G cellular system. However, content delivery over the satellite link poses an enormous challenge to the service provider due to its long latency. The objective of this paper is to develop a video streaming framework over satellite and terrestrial integrated 5G content delivery infrastructure, which is investigated in the EU 5GPPP phase 2 SaT5G Project where satellite link is used as an additional channel as 5G backhaul. In this work, clients send SVC (Scalable Video Coding) layer download request to the Multi-access Edge Computing (MEC) server, which is able to dynamically select a backhaul link (Satellite back-haul or terrestrial) for each layer download request according to specific contexts. The purpose is to achieve optimised content load distribution between the two types of 5G backhaul links. Experiments conducted reveal that the proposed framework is able to achieve a good traffic offloading percentage without compromising with QoE of the end-user.

Innovation of technologies for communication systems, specifically in satellite domain, cloud technologies and 5G terrestrial systems is reaching a point of convergence which promises a new communication paradigm, 5G. It enables a new range of features such as agile service provisioning, multitenancy, software controlled and dynamic management, on-demand service-oriented resource allocation, universal multiaccess, and ubiquitous connectivity. Standardization bodies as 3GPP and ETSI recognize and promote terrestrial and satellite interworking. The complete integration can be achieved with the combination of radio networks, including core and access, and the satellite systems, with computational resources expanded from the core to the network's edge. In this novel ecosystem, a coordination framework is an essential enabler to realize 5G vision. Combined management of different resources will be performed through a MANO-like framework, which is the focus of this paper. The proposed solution provides a user-friendly single point of interaction for all stakeholders in the ecosystem, i.e. terrestrial and satellite operators as well as 5G vertical providers, where they can launch and manage end-to-end 5G services. The system allows easy integration of multiple applications as well as solutions provided by radio and satellite vendors.

We present the design and implementation aspects of a virtualized Performance Enhancing Proxy (vPEP), achieving performance optimizations in a 5G compliant architecture involving the satellite as an alternate, additional backhaul link. The deployment of hybrid terrestrial-satellite configurations is realized through the vPEP agent, meant as a chain of Virtual Network Functions (VNFs) properly distributed at the network edges, enhancing protocol performance and/or bringing value-added services in the end-to-end path. To this end, we present a viable integration pattern of the satellite into the 5G service-based architecture, outlining key functional components. In addition, we present a preliminary evaluation study employing a vPEP embodying the QUIC protocol in a possible web-browsing 5G optimized slice.

Packet Inter-Reception Time Modeling for High-Density Platooning in Varying Surrounding Traffic Density
Guillaume Jornod (Volkswagen AG & TU Braunschweig, Germany); Ahmad El Assaad (Volkswagen, Germany); Andreas Kwoczek (Volkswagen AG, Germany); Thomas Kürner (Technische Universität Braunschweig, Germany)
A recent feature of communications systems is the agile quality of service adaptation, in which the application and the communications system exchange requirements and prediction of quality of service. The application first provides its quality of service requirement. The communications system tries to enforce it, and makes a prediction of the available quality of service. Finally, the application adapts its settings to the future quality of service and provides updated requirements. Though this concept is originally designed for cellular-based technologies, it is also applicable to ad-hoc communication systems. In this paper, we focus on the prediction of quality of service for ad-hoc communications in a high-density platooning system. The quality of service of interest is the packet inter-reception time in an IEEE 802.11p network. Our platooning system drives through different vehicular traffic conditions, in which we gather transmission and position data. We then analyze the distribution of the packet inter-reception time to select the model features and then fit multiple distribution models. This empirical prediction modeling will then be the baseline for future modeling.

We analyze the performance of different channel models and Radio Access Technologies (RATs) for platoon emergency braking in a highway scenario. We present a ray tracing channel model and analyze its differences with the WINNER+ stochastic channel model in terms of the pathloss calculation. Thanks to the consideration of obstacles and their reflections, the ray tracing channel model as been shown to be more realistic in near Tx-Rx distance. This corroborates the results of our performance comparison which highlights larger differences in close Tx-Rx pairs. Considering the simulation time consumption and the more realistic ray tracing predictions, we propose a new models usage for our simulations: a combination of WINNER+ and ray tracing channel models. Moreover, we implement one new 5G numerology on the basis of Long Term Evolution-Vehicles (LTE-V) for Vehicle-to-everything (V2X) communications. We include this new feature in our benchmarking setup and provide performance analysis results. It provides a basis for our future research of further 5G components.
A Lane Merge Coordination Model for a V2X Scenario

Cooperative driving using connectivity services has been a promising avenue for autonomous vehicles, with the low latency and further reliability support provided by 5th Generation Mobile Network (5G). In this paper, we present an application for lane merge coordination based on a centralised system, for connected cars. This application delivers trajectory recommendations to the connected vehicles on the road. The application comprises of a Traffic Orchestrator as the main component. We apply applies machine learning and data analysis to predict whether a connected vehicle can complete the cooperative manoeuvre of lane merge successfully. Furthermore, the acceleration and heading parameters that are necessary for completion of a safe merge, are elaborated. Results demonstrate performance of several existing algorithms and how their main parameters were selected to avoid overfitting.

The European Commission Horizon 2020 AUTOPILOT (AUTOmated driving Progressed by Internet Of Things) is aiming to exploit the IoT ecosystem to integrate connected cars and transform them in automated moving "objects". One of the key challenges encountered in the project is to ensure interoperability of the different components and IoT platforms serving e.g. in-vehicle and road-side devices and sensors. The adopted solution is the use of Federated IoT platforms, with the oneM2M Interoperability Platform used to ensure that all components are able to communicate to each other. This paper provides a high-level description of the project and its goals and then concentrates on the importance to ensure interoperability support for IoT platforms using the standard IoT platform provided by oneM2M.

Automated driving is expected to enormously evolve the transportation industry and ecosystems. Advancement in communications and sensor technologies have further accelerated the realization process of the autonomous driving goals. There are a number of autonomous driving initiatives around the world with varying objectives and scope e.g., vehicle perception in a controlled environment or highway settings. Autonomous driving in urban environments with mixed traffic poses major challenges. The solutions for such environments is the focus of this paper. We start with a quick overview of current autonomous driving development activities worldwide. We then discuss the solution concept for autonomous driving in urban environments and its enabling components, e.g., road digitization and flexible communication infrastructure, to realize an urban autonomous driving testbed. We demonstrate an AI-based approach for the analysis of real traffic data measured on the testbed. The learned traffic demands provide valuable patterns for efficient, low delay management of various autonomous driving infrastructure operations, e.g., 5G mobile network, edge infrastructure, and vertical services.

Chair: Luis M. Correia (IST/INESC-ID - University of Lisbon & INESC, Portugal)


As we see 5G unfold, expectations on the economic and societal impact are very high. Many new opportunities shall emerge for new business opportunities. Besides Gb/s data rates, the Tactile Internet being the most highlighted promise of 5G, enabling remote control applications over cellular. We shall review opportunities and their technical requirements. This helps to build an understanding to detect missing pieces.

1G was a great step creating the vision of ubiquitous voice telephony, but we needed 2G to deliver (like international roaming). 3G was a great step towards ubiquitous cellular data, but we needed 4G to fix the challenges. 5G will be an infliction point in bringing cellular to new applications. However, do we need to use the 5G system to understand what is really needed, and have to wait for 6G as a fix? And is this fix required to make the Tactile Internet a reality?

Completing the 5G vision - Overview of the Industry Roadmap
Ulrich Dropmann (Head of Standardization, Bell Labs - CTO, Nokia, Germany)
Room: Auditorium 2
Chair: Luis M. Correia (IST/INESC-ID - University of Lisbon & INESC, Portugal)


First 5G networks are launched - mission accomplished?

While the commercial launch of the first 5G networks is a significant mile-stone it merely represents the completion of the basement of the 5G House, and that house will only be complete when the full 5G vision has turned into a reality for all. The 5G vision, capabilities, target architecture and transformational properties are well understood in the community of networks and communication professionals. So, in this key note provide an overview on key initiatives the industry engages on to complete the 5G House. Standardization and Industry Initiatives often are tightly linked to prior work as done in funded research. Hence a broad landscape overview of the standard and Industry Initiatives is highly relevant for EuCNC conference. We will cover three main dimensions:

  1. Toward a full 5G standard with all enabling capabilities

By mid-2019, the second phase of 5G standard is fully worked on with 3GPP Rel 16, the evaluation of IMT-2020 is ongoing in the ITU-R. The further priorities of the next 5G Release (3GPP Rel 17) are also take shape. Even certain key enhancements for subsequent releases are clear. We give an overview of that work program highlighting key work items which complement 5G vision capabilities.

  1. Transformation toward open, agile and fully automated network

The promise of 5G will only be realized with open, agile and fully automated networks. Starting with the virtualization of network functions some years ago, several key initiatives have been undertaken in Industry standard and open source projects to address various aspect of opening the network as well as to automate its operation, such as ONAP, O-RAN, ZSM, only to name a few. We highlight which problems these initiatives are solving and how, the relationship among them as well as their status and program ahead.

  1. Beyond telecom ecosystem

One defining characteristic of 5G is the ubiquity of relevance beyond the direct telco sector. That has led to numerous activities to collaborate with different such sectors, understand the requirements and make sure the technology will finally address their needs. There are initiatives around automotive and autonomous mobility (5GAA), Public Safety (TCCA BIG) and more. Further there are groups working on 5G for satellite links, use in future railway systems, as a means to deliver terrestrial broadcast and more. Addressing the needs of Connected Industries and Automation for 5G enabled Industry 4.0 has lead to the creation of the 5G-ACIA (Alliance for Connected Industries and Automation). As 5G enabled Industrial IoT will represent one of the largest opportunities we will elaborate on this further.

Future Connectivity and Network Security
Room: Auditorium 2


Bengt Sahlin (Research Leader, Network Security, Ericsson Research NomadicLab, Sweden)

Motivation and Background:

5G infrastructures constitute a whole new level for connectivity in the digital economy. Beyond consumer services, 5G technology is designed to greatly change the way areas such as transport, industry, energy and health work. Applicability of 5G in these new sectors introduces new security challenges to consider. This trend will further intensify when moving into the future; In the mid- to long-term, the strategic importance of future Smart Networks (namely beyond 5G and later 6G network systems) calls for a strongly structured R&I roadmap with regards to cybersecurity.

Against the above background, following the expressed support from the Member States for a concerted approach to the security of 5G networks, the European Commission issued on 26 March a Recommendation to assess cybersecurity risks of 5G networks and to strengthen preventive measures, helping EU Member States to implement them in a coherent manner. (Commission Recommendation of 26 March 2019 on Cybersecurity of 5G networks C(2019) 2335

In terms of standardization, 5G phase 1 work has been completed in 3GPP, and phase 2 work is ongoing. Phase 1 work concentrated on the mobile broadband use case, phase 2 will have focus on use cases for massive IOT, Industrial Internet and mission critical services. New technology paradigms like SDN, virtualization and network slicing are impacting on how future networks are designed, implemented and deployed. This will have impact on how to design, implement and operate networks securely.

In addition to the existing trends, there are also emerging trends like AI, quantum computing and blockchain arising. As for other technology paradigms, there will be impacts on security.

The panel will present the Commission Recommendation on Cybersecurity of 5G networks, its status and next steps. It will also provide a short overview of security of 5G phase 1 (3GPP Rel-15) and the ongoing security work for phase 2 (3GPP Rel-16). Based on this, the panel will discuss future needs and expectations on security for future networks and services, also in the light of the Commission Recommendation. This discussion will cover aspects relevant for the different use cases (mobile broadband, IOT, mission critical services) and how the security challenges related to the new and emerging technology paradigms can be dealt with.


  • Why the Commission published a Recommendation on Cybersecurity of 5G networks and what are the expected results of all related policy actions?
  • What are the expectations on security specified in 3GPP Rel-16 for IOT and mission critical services?
  • What security aspects should be considered for future networks beyond 5G?

Demand from new applications poses technological challenges for future communication networks. For some specific use cases, satellite networks can provide a complementary solution to terrestrial deployments. However, combining 5G and satellite networks requires close collaboration between different stakeholders, which poses new business challenges. This paper aims to evaluate, from a business-model point of view, the role of a radio-resource broker in the case of integration of the satellite communication into 5G networks. The paper concludes that a broker can lead to efficiency gains, if certain technical challenges are overcome and if it is overseen by a regulatory body. The broker is envisaged to operate on a medium time-scale of the order of hours, resulting in some degree of automation in resource allocation.

The main aim of this paper is to study feasibility and analyse performance of the existing 4G cellular networks at sub-6 GHz and millimeter wave carriers for vehicle-to-network applications. For this purpose, road-side network coverage, signal-to-interference-plus-noise (SINR), throughput and handover rate are used as key performance indicators (KPIs). The KPIs are calculated over realistic vehicular user routes which are created by Google maps. The channel pathloss is simulated using WinProp, a ray tracing software. It is shown that, for existing small cell deployments, which are primarily meant to serve the macrocell edge users, the coverage is fragmented at 28 GHz carrier.
On the Deployment of Large Scale NSaaS
Thomas Deiss, Bertold Dickhaus and Dereje Kifle (Nokia, Germany)
Network Slicing is an enabling technology of 5G mobile networks. Multiple logical networks, i.e. network slice instances, satisfying different service level requirements can be deployed on the same physical infrastructure. Each of these logical networks can be described as a network service descriptor as defined by ETSI NFV. Although ETSI NFV defines support for physical network functions and for deployments across multiple datacenters, these topics are taken to a new level of scale in 5G network slices. In this paper we describe issues caused by this level of scales and which have to be solved both in describing a 5G network slice and in deploying it as a service (NSaaS). We also describe how these issues have been tackled in the 5G-TRANSFORMER project.

New video use cases, which have never been studied in the past in mobile networks, arise when dealing with high bandwidth and low latency video as 5G is being deployed. Careful planning, measures collection and KPI identification techniques are proposed to ensure viability in the real world. In this paper two use cases , one for eMBB (enhanced Mobile Broadband) and another one for URLLC (Ultra Reliable Low Latency Communications) are presented with their related strategies for obtaining and processing the appropriate measures and KPIs. Real activities performed as part of H2020 ICT-18-2018 5G-MOBIX research project in a road corridor between Vigo in Spain and Porto in Portugal are also described.
MESON: Facilitating Cross-Slice Communications for Enhanced Service Delivery at the Edge

Telecom Solutions, Greece); Panagiotis Papadimitriou and Georgios Papathanail (University of Macedonia, Greece); Dimitrios Dechouniotis (National Technical University of Athens, Greece); Symeon Papavassiliou (ICCS/National Technical University of Athens, Greece)
Enabled by NFV/SDN technologies, network slicing promises the provisioning of network services tailored to the needs of vertical service providers. Focusing on resource and performance isolation, as well as security concerns linked to multi-tenancy, emerging management and orchestration (MANO) frameworks typically offer network slices in the form of isolated silos of network, compute and storage resources, across the network infrastructure, including the edge. In this paper, we challenge the holistic applicability of this approach, advocating the careful orchestration of cross-slice communications (CSC). We argue that multi-tenancy and service co-location presents unique opportunities for B2B interactions, inter-service communications and service composition, especially in the case of edge computing and location-based services. However, network slice isolation in its prevailing form raises significant concerns related to performance and resource utilization. In this context, we present MESON, a MANO framework aiming at facilitating cross-service/cross-slice communications and further identify and discuss key challenges towards the support of secure and optimized cross-slice communications at the edge of the network.
5G Network Slicing Based on SDN and Machine Learning
Jose Costa-Requena (Aalto University, Finland); Abdulkadir Mohammedadem (Cumucore, Finland)
This paper describes the current limitations of networking technologies when applied to 5G mobile backhaul. In 5G the same network must fulfil a diverse set of QoS requirements for URLLC, Massive Internet of Things (MIoT) or enhanced Mobile Broadband (eMBB) communications. In the past mobile backhaul network have fulfilled the traffic requirements based on over-dimensioning and pre-provisioning that ensure enough capacity for best-effort IP based networks. However, network slicing is completely dynamic and cannot be deployed based on over-dimensioning due unpredicted needs for slices with different requirements. The assigned resources can be increased and decreased in size based on user needs and policies that change over time. The slices might be created and terminated dynamically based on end-user requirements. This paper presents a design that integrates Software Defined Networking (SDN) with Machine Learning (MJ) for efficient management of network slicing in 5G mobile backhaul.
IoT Gateway Virtualization for 5G mMTC Network Slicing
Vasileios Theodorou and Konstantinos V. Katsaros (Intracom S.A. Telecom Solutions, Greece); Christos Tranoris and Spyros Denazis (University of Patras, Greece)
The expected 5G support for massive machine type communications (mMTC), promises the simplification of IoT infrastructure deployment and operation, via scalable cellular coverage. This in turn supports a convergence between the IoT platform and the telecommunication domains, allowing for the integration of IoT platform capabilities within the operational scope of 5G networks. It follows that the support of IoT-enabled vertical domains goes through the envisioned 5G service orchestration mechanisms, allowing the flexible and programmable deployment and management of the corresponding services. In this paper, we take a first step towards the integration of network slicing capabilities and IoT resources, by presenting a novel approach for the support of network slicing for mMTC. Focusing on the shareability of existing IoT resources, we introduce a modular slicing architecture, which enables virtualization at the IoT GW level and mediated, coordinated communication with IoT devices. Based on this architecture and supporting orchestration mechanisms, we illustrate our proof of concept prototype based on open source components.

Following the convergence of the mobile communications and cloud computing industries, current 4G services evolve towards 5G cloud native ones. Mobile Network Operators (MNOs) leverage cloud-computing paradigms for reducing Operational Expenditures and injecting more and more automation in their mobile network infrastructure. To achieve this vision, multiple components from the orchestration level to the infrastructure level and from the application to the terminal need to be integrated and tested. In this paper we propose an integrated mobile networking system based on Open Source software. We also propose an ONAP-based automation framework to deploy Cloud Native Functions (CNFs) such as CloudRAN based on OpenAirInterface (OAI). Finally, we introduce the design and implementation of a prioritization mechanism inside OAI.
On the Uplink Spectral Efficiency of FBMC Systems
Davide Mattera (Università degli Studi di Napoli Federico II, Italy); Mario Tanda (Università di Napoli Federico II, Italy); Maurice Bellanger (CNAM, France)
The analysis of the spectral efficiency that can be achieved by using two kinds of modulations, namely OQAM and PAM, in FBMC transceivers in the uplink of the modern wireless networks is carried out. Such efficiency is studied in a scenario where the limitations are introduced by interferences due to the multiple access scenario, rather than by the presence of hostile wireless channels. The analysis shows that FBMC-OQAM transceivers are able to achieve significant values of spectral efficiency also in the most difficult conditions, i.e., when the subcarriers blocks to be shared according to a time multiplexing approach are much small; however, when the frequency block assigned to each terminal becomes larger, the FBMC-PAM transceiver is better suited and it optimizes the spectral efficiency.
An Enhanced Version of IEEE 802.15.4 Standard Compliant Transceiver Supporting Variable Data Rate
Muhammad Aslam and Xianjun Jiao (Ghent University - imec, IDLab, Belgium); Wei Liu (University Ghent - imec, Belgium); Ingrid Moerman (Ghent University - imec, Belgium)
In Industrial Wireless Sensor Networks (IWSN), standard compliant state-of-the-art devices typically provide fixed data rate (for instance, IEEE 802.15.4 based devices has a 250kbps with fixed Bandwidth (BW) of 2MHz in 2.4GHz.). The fixed BW restricts these devices from presenting their optimal performance in a continuously varying radio spectrum environment, i.e., narrow-band modes fit best in a crowded spectrum, whereas wide-band modes perform better for low latency scenario). The flexible feature of a Software Defined Radio (SDR) allows us to propose a communication system capable of operating in both standard BW and non-standard BW modes with the same hardware accelerator. In this work, IEEE 802.15.4 compliant SDR transceiver is introduced, where flexible Medium Access Control (MAC) and Physical (PHY) layers are implemented in Time-Annotated Instruction Set Computer (TAISC) and FPGA, respectively. This unique introduction of flexibility at both layers enables our solution to operate in multiple modes which can be categorized into the three subtypes depending on the signal bandwidth, i.e. Narrow-Band (NB), standard compliant, and Wide-Band (WB). The multi-band feature enables the solution to work efficiently in a diverse radio spectrum environment. Experimental results unveil that our transceiver provides receiver sensitivity of -107dBm, -98dBm, and -90dBm when it is configured in NB, standard and, WB modes respectively.
Performance Evaluation of THz Wireless Systems Under the Joint Impact of Misalignment Fading and Phase Noise
Evangelos N. Papasotiriou, Alexandros-Apostolos A Boulogeorgos and Angeliki Alexiou (University of Piraeus, Greece)
In this paper, we investigate the joint impact of misalignment fading and local oscillator (LO) phase noise (PHN) in multi-carrier terahertz (THz) wireless systems operating the range of 275 to 400 GHz. In more detail, after establishing a suitable system model that take into account the particularities of the THz channel, namely path-loss, atmospheric conditions, attenuation due to aerosols, the stochastic nature of antenna misalignment, due to natural phenomenon, as well as the transceivers characteristics, i.e., antenna gains and the level of LO imperfections, we present Monte-Carlo simulation results that quantify the joint impact of misalignment fading and PHN in terms of average signal-to-interference-plus-noise ratio and outage probability.
Index Modulated Orthogonal Frequency Division Multiplexing with Quasi-Orthogonal Sequence
Hyeongseok Kim, Myeonggil Yeom and Jeongchang Kim (Korea Maritime and Ocean University, Korea)
This paper proposes an index modulated orthogonal frequency division multiplexing with quasi-orthogonal sequence (IM-OFDM-QOS) system. The number of available sequences of QOS is larger than the orthogonal sequence such as Walsh sequence. Therefore, by applying QOS to OFDM with index modulation (OFDM-IM) system, the proposed system can improve the spectrum efficiency compared to the conventional OFDM-IM and IM-OFDM with spread spectrum (IM-OFDM-SS) systems. Simulation results show that the proposed system outperforms the conventional OFDM-IM and IM-OFDM-SS systems for a given data rate.
Clustering-based mmWave Channel Propagation Models for Outdoor Urban Scenarios
Bogdan Antonescu, Miead Tehrani Moayyed and Stefano Basagni (Northeastern University, USA)
This paper concerns the task of generating simpler yet accurate mmWave channel models based on clustering all multipath components arriving at the receiver. Our work focuses on communications in urban outdoor scenarios simulated with a ray-tracer tool. We investigate the effectiveness of k-means and k-power-means clustering algorithms in predicting the number of clusters through the use of cluster validity indices (CVIs) and score fusion techniques. Our results show how these two solutions generate accurate approximation of the mmWave channel model, greatly simplifying the complexity of analyzing large amount of rays at any receiver location.

Greece, Greece); Aurora Ramos (Atos, Spain); Panagiotis Gouvas (Ubitech, Greece); Anastasios Zafeiropoulos (UBITECH & National Technical University of Athens, Greece); Roberto Bruschi (CNIT, Italy)
5G networks will constitute a complete transformation in the ICT domain by enabling the deployment of vertical services within the network infrastructures, based on extensive use of network softwarization and programmability. This shift will trigger and facilitate the transformation of existing stakeholders' roles, as well as the interactions between multiple stakeholders from the traditionally separated markets. The 5G-PPP project MATILDA aims at delivering a holistic 5G end-to-end services operational framework, including 5G-ready applications lifecycle management from development to deployment over 5G network infrastructures. This paper aims at providing a refined and extended vision of the 5G business roles and their interactions and based on these at defining business applicability of the MATILDA project, with special focus on the project's value proposition addressing the Telecommunication Service Providers.
Architecture Proposal for SD-IoT Deployments with a Decoupling of Gateway Functionalities
Jara Suárez de Puga and Andreu Belsa (Universitat Politècnica de València, Spain); Carlos E Palau (Universitat Politecnica Valencia, Spain)
the flexibility and programmability offered by Software Defined Networking (SDN) emerge as an approach to resolve some of the main challenges that Internet of Things deployments expose. In the present article we explore the application of SDN paradigm onto IoT deployments. For this purpose, an architecture is defined with the novelty of decoupling the functionalities of traditional IoT gateways in two main components; the physical gateway, located next to the devices, that implements access network and data forwarding, and the virtual gateway, located in the SDN network, that performs more resource consumption processes. In this architecture the core infrastructure is create by means of SDN tools, using OpenVSwitch, RYU controller and a developed application to provide basic QoS services. Over this infrastructure the virtual gateways are created as a service, when a new physical gateway needs to be connected, demonstrating the flexibility and adaptability of the SDN network. Also, IoT platforms can be deployed over this infrastructure thus the data can finally be processed and stored on them. To validate the architecture, a real scenario is considered and recreated, with different measurement recorded over it in order to demonstrate the feasibility of the proposal.
An Analysis of Redundancy Schemes on Cloud Radio Access Network Reliability
Kunjan Shah and Sina Khatibi (NOMOR Research GmbH, Germany); Borislava Gajic (Nokia Bell Labs, Germany)
While moving towards next-generation wireless technology, network virtualisation is a key pillar among major enablers. In addition to improved cost efficiency and less hardware dependency, virtualisation presents an enabler for improved network reliability including Radio Access Network (RAN) reliability by utilising redundant virtual instances. This paper presents a framework for analysis of redundancy schemes to improve cloud RAN reliability. It describes the different modes for utilising redundancy in RAN and RAN self-healing procedures, i.e. steps taken to heal a faulty RAN VNF instance and to bring into the fully functional state again. In this respect, the paper analyses different redundancy schemes through extensive simulations. Each scheme maps to a specific set of the requirement in terms of virtual resource requirement and resulting achieved availability of RAN. The novelty of the paper is Quality of Service impact for different schemes during an event of a failure within virtualised RAN. Results shows with the redundancy schemes reliability of five-nines is possible. Using the presented approaches, stakeholders can accordingly tailor the network deployment to achieve a specific set of service goals.

Jasmin Musovic (Communications Regulatory Agency, Bosnia and Herzegovina); Vlatko Lipovac (University of Dubrovnik, Croatia)
In this paper we present an analytical model for planning and using network resources to improve network coverage, capacity and reliability, reduce network investment and maintenance costs, as well as reduce the electrical power consumption. The analysis considers the downlink of an arbitrary heterogeneous cellular network by using tools of stochastic geometry that adopts the distribution of base stations in the form of Poisson Point Process. To prove the analytical model, simulation based on ns3 network simulator has been conducted, with accurately matching the theoretical values and boundaries.

The outstanding potentiality of the spectrum above 100 GHz for the backhaul of dense small cell architectures at level of tens of Gb/s needs substantial technology advancement. The short wavelength affects the dimensions of the components posing fabrication challenges. In addition, the decrease of transmission power at the increase of the frequency is a design constraint for the proper link budget calculation. The Horizon 2020 project ULTRAWAVE is progressing in the enabling of the first ultracapacity layer at Gigabit per second class by creating a mesh network of area sector at D-band (141 -148.5 GHz) with fronthaul at G-band ( 275 - 305 GHz) with a minimum number of fiber access points. The paper will describe the system specification of the ultracapacity layer and the millimeter wave technology in development.
D-Band Transport Solution to 5G and Beyond 5G Cellular Networks

The mobile data traffic increase and the future connection of billion of Internet of Things (IoT) devices require operators to reshape the existing transport network architecture. Today, more than 50 % of Base-stations (BTS) are backhauled via radio. Radio technology can continue to play this vital role in future transport networks if it is able to evolve to cope with the new capacity level and latency requirements supporting the new 5G services. In this paper, a possible answer to this demand is provided, proposing a radio solution working in D-Band (130-170 GHz) and enabling a reconfigurable meshed network that can support the backhaul needs of future 5G and beyond networks.
Simple Molecular Absorption Loss Model for 200-450 Gigahertz Frequency Band
Joonas Kokkoniemi, Janne Lehtomäki and Markku Juntti (University of Oulu, Finland)
This paper derives a simplified polynomial molecular absorption loss model for 200-450 GHz band. This band has a high potential for near future short range, high data rate applications due to large spectral resources and reasonable path loss. The frequencies around 300 GHz are among the first ones where the molecular absorption loss becomes a significant factor. This loss increases exponentially with the distance and is not a major issue at short distances (few meters), but entirely blocks signals over large distances. Modeling of the molecular absorption loss is relatively straightforward, but requires large numbers of parameters from spectroscopic databases. This paper derives a simplified polynomial absorption loss model for the major absorption lines. This extends and gives more accurate absorption loss values in comparison to the existing ITU-R absorption loss models. The simplified polynomial expressions by ITU-R are mostly limited to about 350 GHz frequency, although being rather accurate up to about 400 GHz. This paper gives a simpler and more accurate absorption loss model to those bands. A part of the considered band, 275-450 GHz band, is subject to World Radiocommunication Conference 2019 (WRC-19) for allocation and operational characterization for the future communication applications.
RGB Demultiplexer Based on Multicore Polymer Optical Fiber
Dror Malka (Holon Institute of Technology & MostlyTek, Israel); Moshe Ran (MostlyTek, Israel); Rami Dadabayev (Holon Institute of Technology, Israel)
Wavelength division multiplexing (WDM) is a good solution for increasing data bitrate communication of multicore polymer optical fiber (MC-POF) based visible light communication (VLC) system. However, this solution requires adding more optical components to the system which can limit its performance. In order to solve this issue, we propose a new design for an RGB demultiplexer based on polycarbonate (PC) MC-POF structure. The new structure is based on replacing several air-holes areas with PC layers over the fiber length which enables controlling the light propagation direction between the pc layers. The positions of the PC layers and the key geometrical parameters of the MC-POF were optimized and analyzed utilizing the beam propagation method (BPM). Results show that an RGB wavelength splitter can be obtained over a light propagation of 20 mm with an excellent crosstalk of -19.436 to -26.474 dB, low losses of 0.901 to 1.246 dB and a large bandwidth of 5.6 to 11.3 nm.

In this work, we provide first-in-class measurement results for fast-convolution-based filtered orthogonal frequency-division multiplexing (FC-F-OFDM) processing implemented on a universal software radio peripheral (USRP) software-defined radio (SDR). The fast-convolution-based filter bank is a highly efficient and flexible scheme allowing to achieve high spectral utilization in all channel bandwidths. As per the transmitter output radio-frequency (RF) spectrum emissions, we show that FC-F-OFDM allows to increase spectrum utilization compared to the fifth generation new radio (5G NR) Release-15 requirements. Furthermore, considering the out-of-band emission masks and adjacent-channel-leakage-ratio requirements, FC-F-OFDM provides a larger interference margin than well-known windowed overlap-and-add OFDM processing.

Currently, there is a relentless activity to conduct trials of 5G technology in realistic situations, targeting use cases that are driven by vertical stakeholders. Aligned with this strand and capitalizing on the recent standardization efforts of 3GPP that recently froze Release 15, we provide overview of an industry grade 5G experimental platform that targets the next generation of In-Flight Entertainment and Connectivity (IFEC) services, when we consider the airplane is a self-contained edge environment. The platform is developed as part of the 5G ESSENCE project activities. The contributions of this paper are multiple: describe the IFEC market from a general standpoint, show the hardware and software constituents of the 5G platform and present two virtualized services, namely virtualized video transcoding and caching, which are forecast to play an important role for the future of IFEC on commercial flights.
A Novel Multi-Factored Replacement Algorithm for In-Network Content Caching
Lijun Dong (Futurewei Technologies, USA); Richard Li (Huawei USA, USA)
The paper takes multiple new factors into consideration in designing the optimal replacement algorithm for in-network content caching, i.e. requester's tolerance to common semantics information of requested content, latency requirement on content arrival. The paper proposes a new metric, named importance value, to indicate a content is important enough to be cached in the network. By formulating a 0-1 knapsack optimization problem, an algorithm based on dynamic programming is proposed (named MTT). The performance valuations show the proposed MTT algorithm improves over the existing Least Recently Used (LRU) and popularity based replacement algorithms in achieving shorter response time in various content popularity settings.
Application of Deep Learning Techniques to Video QoE Prediction in Smartphones
Carlos Cárdenas Angelat and Janie Baños Polglase (DEKRA, Spain); Cristian Vaca-Rubio and Mari Carmen Aguayo-Torres (Universidad de Malaga, Spain)
This paper evaluates the use of deep learning prediction models for assessing the quality of experience of video applications using input data from a single measuring point at the smartphone. Three architectures for deep neural networks, single task \ac{FC}, multitask \ac{FC} and convolutional, have been implemented. A set of four relevant metrics recommended by ITU-T models has been considered as outputs for the prediction models. The amount of data received by the device, a parameter which can be easily extracted from the majority of smartphones, is used as input to the machine learning algorithms. For the convolutional neural model, the amount of transmitted data is also used as input. The predictions models have been applied to evaluate YouTube applications on smartphones, but could be generalized to other services. The overall achieved performance on the test set is around 90\%, a very promising result as the generation of new labelled datasets is quite feasible at low cost thanks to the fully automated test setup developed.

The transmission performance of cross-polarized MIMO is being studied to determine how to increase the capacity of terrestrial broadcasting and make it more robust. As an initial work on MIMO transmission, the authors evaluated the performance by field experiments in two scenarios. Results showed that when the transmission capacity is increased by MIMO using transmission parameters with the same robustness as SISO, although the degradation in the required received power from the laboratory test is increased by about 0.4 dB, the transmission capacity can be doubled. We confirmed that the required received power can be improved by 9.3 dB when MIMO is introduced to enhance transmission robustness, i.e., maintaining the same transmission capacity as SISO. The field trials were performed using a transmission system for next-generation terrestrial broadcasting being studied in Japan, but it also shows promise for wireless communication systems that introduce MIMO into the HPHT network using the UHF band in urban areas.
Practical Cross-Layer Testing of HARQ-Induced Delay Variation on IP/RTP QoS and VoLTE QoE
Adriana Lipovac, Anamaria Bjelopera, Ivan Grbavac, Ines Obradović and Tomo Sjekavica (University of Dubrovnik, Croatia)
As the LTE PHY/MAC-layer IR HARQ and RLC-layer ARQ protocol, adopted in LTE, may create sudden ramping of the delay when retransmissions occur, the arising question is whether these significantly and dominantly contribute to the overall packet delay or not? With this regard, in addition to the TCP retransmissions, with LTE protocol stack, there are two more retransmitting layers - the PHY/MAC and the RLC, which may impose intolerable additional delay of data blocks and so of the IP and finally the RTP packets, which further on may significantly degrade the end-to-end voice QoE, especially when voice is to be transmitted over LTE. We propose and demonstrate a VoLTE QoS and QoE test procedure based on cross-layer protocol analysis (HARQ/IP/TCP-UDP/RTP) and perceptual speech quality measurements. It has been shown how this concept can be used as an integral QoS criterion during the installation, commissioning and maintenance of VoLTE networks.

Telco Cloud Resilience: Synergies Between Fault and Security Management
Borislava Gajic (Nokia Bell Labs, Germany); Ruben Trapero Burgos (Atos, Spain); Diomidis S. Michalopoulos (Nokia Bell Labs, Germany)
This work capitalizes on the concept of network function virtualization at the telco cloud, and presents a joint study between fault management and security management. Specifically, the commonalities of fault and security management are put forward, along with a resource allocation study in common slice deployments. In this regard, a security threat analysis is presented, which sheds light onto the impact of security threats on network fault management. The interdependence between security and fault management is highlighted via three use cases, where distinct levels of resource trade-offs are identified. Along with such use cases, the paper provides also an overview of the resulting resource allocation process, where the requirements of the corresponding slice are analyzed towards an overall efficient resource usage.
Towards the Detection of Mobile DDoS Attacks in 5G Multi-Tenant Networks
Ana Serrano, Zeeshan Pervez, Qi Wang and Jose Alcaraz-Calero (University of the West of Scotland, United Kingdom (Great Britain))
The fifth-generation (5G) mobile networks target a variety of new use cases that involve a massive amount of heterogeneous devices connected to the same infrastructure. This trend also brings new security threats, and one of the most critical ones for the availability of network services is a Distributed Denial of Service (DDoS) attack. A small portion of the billions of connected devices can be employed as a botnet to trigger a massive DDoS flooding attack that can bring down important services or affect the complete infrastructure. Traditional security systems against DDoS attacks are generally designed to work in infrastructures with a particular topology. However, the mobility of many devices subscribed to the network should be taken into account when designing defence systems. Otherwise, both the detection and the trace back of the attacker will be limited to non-mobile devices as the source of the attack. This is specially relevant when security needs to be part of the definition of the network slices associated to the 5G networks. This paper presents a novel approach to overcome the limitation of traditional detection systems. A novel sensor provides the required information to trace back an attacker even if it is moving among different locations. The proposed approach is suitable to be deployed in almost all 5G network segments including the Edge. Architectural design is described and empirical experiments have validated the proposed approach.
Secure Location-Aware VM Deployment on the Edge Through OpenStack and ARM TrustZone
Teodora Sechkova, Enrico Barberis and Michele Paolino (Virtual Open Systems SAS, France)
In recent years, there is an ongoing computational shift from the data center to the network edge. Due to the increased hardware capabilities of devices, the edge can also benefit from the dynamic and scalable services provided by the virtualization technologies. In turn, the edge computing brings low-latency and reduced network traffic, location-awareness and local caching. However, the new capabilities unlock new challenges in terms of security, data and workload location. In this work, we focus on the threats caused by the heterogeneous and distributed nature of the edge infrastructure. We build a trusted edge based on the hardware isolation of ARM TrustZone. Moreover, we use it as a secure foundation to perform location-aware virtual machine deployment utilizing the dispersed nature of the infrastructure. We measure the performance of our solution and discuss the overall overhead and potential improvements.
Applying QKD to Improve Next-Generation Network Infrastructures
Victor Lopez (Telefonica, Spain); Antonio Pastor and Diego Lopez (Telefonica I+D, Spain); Alejandro Aguado Martin (Universidad Politécnica de Madrid, Spain); Vicente Martin (Universidad Politecnica de Madrid, Spain)
There is a great attention to quantum technologies in the ICT environment. In particular, when dealing with security matters, the most prominent quantum technology is Quantum Key Distribution (QKD). QKD allows the sharing of symmetric keys with information theoretic security (ITS, i.e. independently of the computational power of the attacker) between two remote network nodes. QKD is the only known method to share a key able to reach ITS. During the last two decades, there has been a tremendous technological progress in QKD research, that has led to the availability of QKD network demonstrators. Software Defined Networks (SDN) enables the automation of service provisioning within network operator infrastructures. With the advent of web-scale services and dynamic network requirements, operators can not anymore deploy their services based on manual intervention or using proprietary vendor solutions. Programmability is key in the next-generation network infrastructure and any new technology must be integrated with this paradigm. Let us highlight that this requirement is even more important with virtual environments, where a Virtual Network Function (VNF) can be deployed in any point-of-presence of the operator. The new 5G deployments will enable operators to have edge computing services supporting different capabilities, thus increasing even more the complexity to deliver services without any automation. In spite of the high potential of QKD, this technology has not yet found its path to wide adoption, commercialization and deployment. QKD is a physical technology that requires the existence of a quantum channel, a physical connection able to transmit quantum bits without perturbation, making hard its integration in networks. The aim of this document is to present how QKD can be deployed in next generation infrastructures, based on realistic scenarios. To do so, this paper describes the technological components of the solutions, as well as the use cases that motivate such effort. These use cases are described from a telecommunication provider's point of view, as they are the actors in charge of deploying QKD systems in their networks.
An Analytical Cross Layer Model for MultipathTCP (MPTCP)
Garima Mishra (TCS (Research and Innovation), India); Samar Shailendra, Hemant Kumar Rath and Arpan Pal (Tata Consultancy Services, India)
Next-generation network smart devices are equipped with multiple radio interfaces. Multipath TCP (MPTCP) has been proposed in the literature to leverage these multiple interfaces. MPTCP has been augmented with several packet schedulers to split packets on these available interfaces. These schedulers work well in case of wired paths. However, in case of wireless links their performance degrades substantially. This is because the current scheduling algorithm does not explicitly account for the wireless channel characteristics while deciding the link. Moreover, there is not enough analytical work existing in the literature to model the effect of wireless channel properties over the transport layer schedulers. In this paper, we have presented a queuing based model to analyze the effect of wireless channel properties over the MPTCP scheduler. Additionally, we have proposed a packet scheduling algorithm for MPTCP based upon this model. We have compared the theoretical results of our model with that of the simulation results. We have also conducted experiments to evaluate the performance of the proposed packet scheduler using SimEvents based network simulator.

Dynamic Polarimetric Wideband Channel Sounding in an Elevator Shaft
Pasi Koivumäki, Mikko Heino and Katsuyuki Haneda (Aalto University, Finland); Mikko Puranen and Johanna Pesola (KONE Corporation, Finland)
We report results from dynamic polarimetric wideband channel sounding in an elevator shaft for the first time in the literature. Transmitter and receiver are fixed to a roof of an elevator car and top of the elevator shaft, respectively, to test radio link connectivity for infotainment display inside the car. To this end, we develop a real-time wideband channel sounder based on software-defined radios, capable of 160 MHz instantaneous bandwidth with varying carrier frequency from a few hundred MHz to 6 GHz. The sounder does not provide sufficient phase synchronization over time, but delay synchronization was found stable for estimation of absolute delay and Doppler spectrum. The results show significantly higher pathloss at 2:45 GHz for electric fields parallel to the longer side of the shaft than to the shorter side due to a break point. The power delay and Doppler spectrum showed significant amount of scattering for short transmitter-receiver separation due to surrounding clutters. The multipath richness decreased as the separation is longer. For the fixed power threshold in estimating a delay spread, 2:45 GHz channels had a higher estimates than 5:8 GHz when the car is at the top of shaft, while it was lower for the rest of car locations in the shaft.
Putting 5G into Production: Realizing a Smart Manufacturing Vertical Scenario
Stefan Schneider and Manuel Peuster (Paderborn University, Germany); Daniel Behnke and Marcel Müller (Weidmüller Group, Germany); Patrick-Benjamin Bök (Weidmueller Group, Germany); Holger Karl (Paderborn University, Germany)
As 5G and network function virtualization (NFV) are maturing, it becomes crucial to demonstrate their feasibility and benefits by means of vertical scenarios. While 5GPPP has identified smart manufacturing as one of the most important vertical industries, there is still a lack of specific, practical use cases. Using the experience from a large-scale manufacturing company, Weidmüller Group, we present a detailed use case that reflects the needs of real-world manufacturers. We also propose an architecture with specific network services and virtual network functions (VNFs) that realize the use case in practice. As a proof of concept, we implement the required services and deploy them on an emulation-based prototyping platform. Our experimental results indicate that a fully virtualized smart manufacturing use case is not only feasible but also reduces machine interconnection and configuration time and thus improves productivity by orders of magnitude.
Multi-Robot Cooperative Patrolling Algorithm with Sharing Multiple Cycles
Youngtaek Hong, Yeosun Kyung and Seong-Lyun Kim (Yonsei University, Korea)
In this paper, a multiple Cycle Sharing Algorithm, CSA, is proposed to solve Multi-Robot Patrolling Problem, MRPP. In MRPP, vertices in graph are visited by R robots continuously. The evaluation metric of the idleness of the vertices was considered to evaluate the performance of algorithm. Minimizing the average graph idleness and the graph idleness standard deviation was covered because the smaller average idleness means robots visit vertices more frequently and the smaller graph idleness standard deviation means robots visit vertices more regularly. The most effective way to minimize standard deviation is that finds a Hamiltonian cycle in graph. A Hamiltonian cycle is a cycle that visits each vertex exactly once, except for the vertex that is both the start and end, which is visited twice. It is known that finding the minimum cost Hamiltonian cycle, as known as Traveling Salesman Problem, is NP-complete problem which means that if graph size becomes large, finding the minimum cost cycle will require longer time by polynomial. However, by partitioning graph properly into multiple sections with cooperative robots, calculation time can be reduced remarkably.
Achieving Millimeter Precision Distance Estimation Using Two-Way Ranging in the 60 GHz Band
Vladica Sark, Nebojsa Maletic and Marcus Ehrig (IHP, Germany); Jesús Gutiérrez (IHP - Leibniz-Institut für Innovative Mikroelektronik, Germany); Eckhard Grass (IHP & Humboldt-University Berlin, Germany)
The large channel bandwidth of about 2 GHz per channel available in the 60 GHz ISM band enables millimeter precision ranging and positioning. The high localization precision, combined with the multi-gigabit data throughputs achievable in this band represents the launch pad for the development of many new applications. In this paper, we propose an approach for implementation of high-precision ranging in the 60 GHz band. This approach can be also used for achieving precise localization. Our approach uses two way ranging (TWR) for distance estimation between two wireless nodes. It requires minimal hardware implementation effort and performs all the necessary processing in software. The proposed approach was implemented on a custom baseband processing unit with commercial 60 GHz analog frontends. Tests were performed indoors in a lab environment. The obtained results show that a precision and accuracy of less than 5 mm can be achieved. This excellent result outperforms other similar solutions.

Motivation and Background:

The use of AI for network operation and management is known to have great potential to enhance the network performance and efficiency, therefore has received significant interest in both research and industry standardization groups. Prominent industry standard groups, such as ETSI ISG ENI and ZSM, and 3GPP SA2 and SA5, have made great efforts to build industry consensus on network architecture and interfaces to enable the use of AI in the network. However, the standardization on AI in network management and orchestration is just at its beginning. Open questions on AI for network management need joint efforts from different standardization groups, as well as between the research and industry standardization groups.

Likewise, the topic is having a big impact in the research communities, and 5G-PPP projects are also part of this trend. In this workshop, 5G-MoNArch will showcase recent results on the employment of AI to achieve resource elasticity, i.e., an efficient and autonomous utilization of computational resources in the network, by enhancing the design of VNFs and their scaling mechanisms. In SliceNet, AI is investigated to achieve cognitive network management to improve both operation experience for network operators and quality of experience for vertical users, especially in the context of network slicing. However, traditionally it has been difficult for research and innovation projects to make significant impact on standards in a timely manner.

The workshop aims to bridge the gap between research and standards on AI for network management and orchestration. It will bring together researchers and industry experts, and stimulate debate and discussions on what are the significant problems to resolve to fully explore the potential of AI in networks, and how the relevant results provided by 5GPPP projects can be leveraged, therefore maximize their impacts to standards.

Operating a 5G (and beyond-5G) system will be substantially more complex than it used to be in previous generations of mobile networks. To full exploit the advanced features of dynamic reconfiguration introduced by network virtualization technologies in a cost efficient way, network operators shall employ elastic algorithms that can scale resources according to the real demand. In this extended abstract we first introduce the concept of network elasticity and then describe two algorithms for the elastic network operator: (i) CARES, a computational-aware radio scheduler and (ii) DeepCog, a deep learning algorithm for resource orchestration in a multi slice network.

Fifth generation mobile networks (5G) will enable new use cases for industries and vertical markets via numerous innovative approaches that overcome limitations of existing systems. Two concepts essential for the realization of 5G, are network elasticity and slicing. The application of these concepts allows the simultaneous hosting of more services that use a common resource pool while reducing operation and capital expenses. The realization of these benefits demands an efficient method to scale the resources allocated between different slices often with diverse demands. We apply a multi-objective approach, based on evolutionary algorithms to accomplish optimized resource orchestration between cloud-based slices in a 5G network deployed over a large European city. Numerical results are provided for the proposed approach and are compared to other allocation schemes.
Self-Restoring Video User Experience in 5G Networks Based on a Cognitive Network Management Framework

Video applications such as streaming are expected to dominate the traffic of the incoming Fifth generation (5G) networks. It is essential for 5G service video providers and/or network operators to provide assurances for both the overall status of the network and the quality of their video transmissions in order to meet the final users' expectations. In this contribution, we propose a video optimisation scheme which is implemented as a Virtualised Network Function (VNF), which in turn, facilitates its on-demand deployment in a flexible way in response to an intelligent analysis of the current network traffic conditions. We leverage a cognitive network management framework to analyse both network status metrics and video stream requirements to evaluate if any optimisation action is required. The testing and evaluation focus on the functional tests and scalability evaluation of the proposed scheme. Moreover, the bandwidth saving is assessed to demonstrate the significant benefit in traffic reduction for a 5G system that adopts the proposed approach.

Provisioning of network slices with appropriate Quality of Experience (QoE) guarantees is one of the key enablers for 5G networks. However, it poses several challenges in the slice management that need to be addressed to achieve an efficient end-to-end (E2E) services delivery. These challenges, among others, include the estimation of QoE Key Performance Indicators (KPIs) from monitored metrics and the corresponding reconfiguration operations (actuations) in order to support and maintain the desired quality levels. In this context, SliceNet provides a design and an implementation of a cognitive slice management framework that leverages machine learning (ML) techniques in order to proactively maintain network conditions in the required state that assures E2E QoE, as perceived by the vertical customers.

Motivation and Background:

5G is the first generation of mobile networks that is by design addressing the wide range of needs of the vertical industries. 5G offers unlimited mobile broadband experience, provides massive connectivity for everything from human-held smart devices to sensors and machines, and most importantly, it has the ability to support critical machine communications with instant action and ultra-high reliability.

First 5G specifications are available with 3GPP Rel.15, however further enhancements and optimizations are needed to design a 5G System that meets the requirements from the vertical industries.

5GPPP Architecture Working Group was launched during the Phase 1 of the 5GPPP Initiative with the result of publishing two White Papers on 5G Architecture in June 2016 (v1.0) and January 2018 (v2.0). The work is now continuing with the 5GPPP Phase 2 and Phase 3 with special focus on understanding the requirements from vertical industries involved in the projects and then driving the required enhancements of the 5G Architecture able to meet their requirements. The results of the Working Group are captured in a White Paper v3.0 to be released at EuCNC 2019 in June 2019.

In this Workshop, we will present the findings and analyses of the 5GPPP Phase 2 projects and early findings of 5GPPP Phase 3 projects within the white paper framework. While the standard implications on the ongoing specifications, e.g. in 3GPP Rel.16 and ETSI, are highlighted, various achievements presented in the White Paper are also expected to impact 3GPP Rel.17 and beyond Study Items and Work Items. Thus, the timeline matches perfectly as the discussion in 3GPP is going to start mid of 2019.

ONE5G's main objective is to investigate and propose new features and advancements, focussing on the Radio Access Network (RAN) for moving "5G" towards "5G Advanced". To prepare the next releases of 5G, beyond the first version (3GPP Release 15), the areas investigated are advanced multi-link access and interference management supported by massive Multiple-Input Multiple-Output (MIMO) and Centralized Radio Access Networks (CRAN), End-to-End (E2E)-aware performance optimization through advanced radio resource allocation and multi-node connectivity orchestration, load balancing, spectrum management and device-to-device (D2D) communication. The scope of this special session is to present the major technical results in the context of the ONE5G's main, highly diverging, deployment scenarios, i.e. "Megacities" and "Underserved Areas".

Multi-Connectivity Beamforming for Enhanced Reliability and Massive Access
Martin Schubert (Huawei Technologies Duesseldorf GmbH, Munich Office, Germany); Ronald Boehnke (Huawei European Research Center, Germany); Wen Xu (Huawei Technologies Duesseldorf GmbH & - European Research Center (ERC), Germany)
We study the problem of max-min fairness for the uplink of a wireless network with multiple Trans- mission/Reception Points (TRPs) that are equipped with antenna arrays. Each user is connected with several TRPs, which increases the robustness against interference and fading effects. The performance is optimized over beamformers, TRP association, and power allocation. The global optimum is achieved by a normalized fixed point iteration, which is computationally efficient. We evaluate the performance and reliability advantage for a mmWave scenario with dense deployment of TRPs.

This paper provides techno-economic analyses on the network deployments to cover 4 key verticals, under 5G-NR. These verticals, namely Automotive, Smart city, Long range connectivity and Disaster and emergency support, were chosen to reflect the ONE5G project objective of investigating environments from densely populated cities ("Megacity") to large underserved areas. The work presented covers the network deployment framework including common centralization strategies and the main cost factors. Initial results presented for long range connectivity and emergency support networks provide the cost trade-offs in different deployment options and cost sensitivity to some of the parameters.

Achieving Ultra-Reliable Communication via CRAN-enabled Diversity Schemes

Internet of things is in progress to build a smart society, and wireless networks are critical enablers for many of its use cases. In this paper, we present a multi-coordinated transmission scheme to achieve ultra-reliability for critical machine-type wireless communication networks. We take advantage of diversity, which is fundamental for dealing with fading channel impairments, and for achieving ultra-reliable region of operation in order of five 9's as defined by 3GPP standardization bodies. We evaluate an interference-limited network composed of multiple remote radio heads that are allowed to cooperate, by keeping silence thus reducing interference, or by performing more elaborated strategies such as maximal ratio transmission, in order to serve a user equipment with ultra-reliability. We provide extensive numerical analysis and discuss the gains of cooperation by the centralized radio access network.
A Non-orthogonal Waveform Design with Iterative Detection and Decoding for Narrowband IoT Applications
Sumaila Mahama (University of York, United Kingdom (Great Britain)); Yahya Jasim Harbi (University of Kufa, Iraq); Alister G. Burr and David Grace (University of York, United Kingdom (Great Britain))
Narrowband Internet of Things (NB-IoT) was proposed by 3GPP in Release 13 to provide low power wide area connections to a high-volume of devices. With the millions of devices expected to connect to 5G through its massive machinetype communication use case, the strict orthogonality and synchronization requirement of cyclic-prefix orthogonal division multiplexing (CP-OFDM) will demand a very large amount of control information between devices and the core network. To overcome this challenge, we study a new air interface for NBIoT, which utilizes a non-orthogonal multicarrier transmission scheme. The waveform considered in this work is filter-bank muilticarrier with quadrature amplitude modulation (FBMCQAM). The loss of orthogonality in FBMC-QAM results in severe levels of intrinsic interference. Iterative detection and decoding (IDD) using low density parity check (LDPC) encoding and decoding is implemented together with iterative interference cancellation (IIC) to remove the inherent interference and improve the BER rate performance. Simulation results indicate that the proposed IDD receiver can effectively improve BER performance under time-varying channels.
Distributed Spatial Modulation Aided NOMA
Amir Shehni and Mark F. Flanagan (University College Dublin, Ireland)
In this paper, a novel cooperative diversity protocol based on the association of non-orthogonal multiple access (NOMA) and distributed spatial modulation (DSM) is introduced. In the proposed protocol, two source symbols are multiplexed in the power domain, while one source symbol obtains a diversity gain due to its being relayed according to the DSM principle; this doubles the data rate for the source-to-destination link as compared with conventional DSM. We propose two demodulators for use at the destination: an error-aware demodulator which is robust to demodulation errors at the relays, and a suboptimal demodulator which assumes error-free demodulation at the relays. Simulation results demonstrate that while the proposed protocol achieves a source data throughput equal to that of a full-duplex system, its BER performance also significantly outperforms the full-duplex relaying benchmarks of successive relaying and virtual full-duplex DSM.

Murat Temiz (University of Manchester, United Kingdom (Great Britain)); Emad Alsusa (Manchester University, United Kingdom (Great Britain)); Laith Danoon (University of Manchester, United Kingdom (Great Britain))
This study examines the performance of the multi-user multiple-input-multiple-output (massive MIMO) systems with 1-bit, 2-bit and 3-bit analogue to digital converters (ADCs) under channel correlation and channel state information (CSI) errors. The OFDM modulated uplink with QPSK, 16QAM and 32QAM schemes are considered for the communication between the base station (BS) and the user equipment (UEs). The BS antenna array is assumed to be uniform linear (1D) or uniform rectangular (2D) arrays. Zero-Forcing (ZF) receiver has been employed by the BS due to its simplicity and superior performance over other linear receivers. Furthermore, we consider the square root raised cosine filter (SRRC) to enhance the performance of the low-resolution ADC systems. The results show that the resolution of ADCs mainly determines the modulation scheme and having a high-level channel correlation or CSI mismatch requires a higher resolution ADCs. Furthermore, it has been shown that the SRRC filter enhances the system performance even with low-resolution ADCs.
Impact of Polarization Diversity in Massive MIMO for Industry 4.0
Frédéric Challita (University of Lille & IEMN Lab, France); Pierre Laly and Martine Liénard (University of Lille, France); Emmeric Tanghe and Marwan Yusuf (Ghent University, Belgium); Wout Joseph (Ghent University/IMEC, Belgium); Davy P Gaillot (University of Lille, France)
The massive polarimetric radio channel is evaluated in an indoor industrial scenario at 3.5 GHz using a 10x10 uniform rectangular array (URA). The analysis is based on (1) propagation characteristics like the average received power and the power to interference ratio from the Gram matrix and (2) system-oriented metrics such as sum-rate capacity with maximum-ratio transmitter (MRT). The results clearly show the impact of polarization diversity in an industrial scenario and how it can considerably improve different aspects of the system design. Results for sum-rate capacity are promising and show that the extra degree of freedom, provided by polarization diversity, can optimize the performance of a very simple precoder, the MRT.
Downlink Coordinated Beamforming Policies for 5G Millimeter Wave Dense Networks
Marios Gatzianas (Aristotle University of Thessaloniki & International Hellenic University, Greece); Georgios Kalfas and Christos Vagionas (Aristotle University of Thessaloniki, Greece); Agapi Mesodiakaki (Aristotle University of Thessaloniki (AUTH), Greece)
A key technology of the upcoming Fifth Generation (5G) networks, which is expected to crucially affect the achieved system capacity, is Coordinated Multipoint (CoMP), where multiple base stations collaborate with each other to mitigate inter-cell interference. In this paper, we present a Coordinated Beamforming (CB) CoMP policy for dense fixed-wireless millimeter wave networks. This policy, which is based on a standard stochastic optimization methodology, explicitly accounts for realistic antenna radiation patterns and stochastic packet arrivals, in addition to channel state fluctuations. It performs both user scheduling as well as proper radiation pattern selection in order to control interference and can be easily extended to include additional MAC and PHY layer controls. For comparison purposes, two other round-robin policies are proposed. Simulation results indicate that the proposed CB policy is able to achieve a throughput gain up to 2X per user.

Claudia Carciofi (FUB, Italy); Paolo Grazioso, Valeria Petrini and Francesco Matera (Fondazione Ugo Bordoni, Italy)
In this work we show the results of coexistence studies between incumbent systems and the forthcoming 5G networks. The analyses were conducted by means of a simple but rigorous prediction tool and based on the widely adopted Minimum Coupling Loss (MCL) methodology. We considered the pioneer bands identified to offer 5G services in Europe by 2020 on a large scale: the 3.5 GHz and the 26 GHz band, using for each band appropriate propagation models. Results show how coexistence is possible, both on a co-channel and an adjacent channel basis, provided that adequate separation is guaranteed between interfering services.
A Device to Device (D2D) Spectrum Sharing Scheme for Wireless Industrial Applications
Idayat Sanusi (University of Greenwich, United Kingdom (Great Britain)); Karim M. Nasr (University of Greenwich & University of Surrey, United Kingdom (Great Britain)); Klaus Moessner (University of Surrey, United Kingdom (Great Britain))
In this paper, we present a spectrum sharing scheme for Device to Device (D2D) deployments in a wireless Internet of Things (IoT) industrial environment. Interference management for this scheme relies on the relative distance between participating users or devices. The D2D links can access spectrum by sharing resources with cellular users or by using dedicated channels. The presented scheme maximises the throughput of admitted D2D links without compromising the Quality of Service (QoS) requirements of users in the network. An optimisation approach is adopted to solve the spectrum sharing problem resulting in an efficient allocation and throughput maximisation for all participating users and devices.
A High Performance Low Complexity Muting Scheme for Interference Coordination
Ole Grøndalen and Kashif Mahmood (Telenor, Norway)
Modern mobile networks are heterogeneous consisting of a mix of Base Stations (BSs) of different sizes. The interference scenario in such Heterogeneous Networks (HetNets) is very complex and good interference control schemes are needed to make the network cost efficient and ensure good user experience. Interference coordination schemes where selected BSs are muted in some time intervals can ensure that edge users get fair bitrates and good load balancing between small and large cells. However, finding the optimal scheme for muting BSs in a large network is an unsolved problem. In this paper a new method for generating good sets of muting configurations is proposed and its performance evaluated for small networks where the performance of the optimal muting scheme can be found for comparison. The results show that only a small number of muting configurations generated by the new method is needed to achieve a performance within 90% of the maximum achievable. The results of the simulation study also suggest that the muting scheme found by the proposed method has low sensitivity to changes in user and BS positions, indicating that it is sufficient to update the muting scheme at infrequent intervals.
A Method to Tailor Broadcasting and Multicasting Transmission in 5G New Radio
Wei Guo (Samsung, United Kingdom (Great Britain)); Belkacem Mouhouche (Samsung Electronics Research and Development UK, United Kingdom (Great Britain))
Broadcast and multicast will be an important feature supported in 5G New Radio. In this paper a new transmission method is proposed to improve the receiver side User Equipment (UE) resource efficiency by using redundant multicast channels at the transmitting Base Station (BS). Transmission is tailored for UEs with different channel characteristics. A sub-grouping algorithm is designed to fast allocate UEs of a multicast group to their most suitable channels. Numeric sample calculation proves the validity of the proposed method.
A Hybrid Approach for Data Duplication and Network Coding
Jakob Belschner (Deutsche Telekom AG, Germany); Diomidis S. Michalopoulos (Nokia Bell Labs, Germany)
The extreme requirements for 5G ultra-reliable services call for new approaches for achieving a reliable operation of the Radio Access Network (RAN). Data Duplication as well as Network Coding in combination with multi-connectivity are corresponding approaches that promise increased RAN reliability. In this work, the advantages and disadvantages of both Network Coding and Data Duplication are studied. Moreover, a novel hybrid approach is proposed, which combines the advantages of both approaches. The effectiveness of the proposed hybrid approach is corroborated by means of simulations.
Over the Sea UAV Based Communication
Gianluca Fontanesi (University College Dublin, Ireland); Hamed Ahmadi (University of Essex, United Kingdom (Great Britain)); Anding Zhu (University College Dublin, Ireland)
We envision Unmanned Aerial Vehicle (UAV) aided wireless networks as a solution to provide a reliable, low latency cellular link for search and rescue operations over the sea. We propose three different network architectures, based on the technology deployed on the UAV: a flying relay, a flying Base Station (BS) and a flying Remote Radio Head (RRH). We describe the challenges and highlight the benefits of the proposed architectures from the perspective of search and rescue operations over the sea. We compare the performance in term of data rate and latency, analyzing different solutions to provide a backhaul/fronthaul link for long coverage over the sea. Results show that a system architecture is not outperforming over the others. A cost function is thus indicated as a tool to find a suboptimal solution.

With more and more IoT devices are deployed, our daily life will produce large amount of data. If we transmit these big data to the cloud servers directly, it would result in network traffic congestion in the cloud. In order to solve this problem, this paper using the Edge Computing to process data locally which means that processing data closer to where data be created. With the edge computing, it can reduce the latency from network transmission and it also can do real-time analytics. Although the edge computing solved some problem, it brought another problem here, how to decide what data should process in edge network and what should send to the cloud server. This problem will greatly affect the performance of the system. Therefore, this paper defined this problem as Dynamic Multiple Resource Management (DMRM) problem and discusses the solution for the resource allocation in dynamic environment with multiple resources. For the DMRM problem, this paper proposed the Multi-Resource Binary Particle Swarm Optimization (MR-BPSO) and also do some experiment comparing with other resource allocation methods. According to the experiments, the MR-BPSO has excellent performance and suitable for dynamic environment.
Energy-Efficient and Reliable MEC Offloading for Heterogeneous Industrial IoT Networks
Che-Wei Hsu, Yung-Lin Hsu and Hung-Yu Wei (National Taiwan University, Taiwan)
The ultra-reliable and low latency communication (URLLC) and massive machine type communication (mMTC) in 5G are envisioned to support intelligent automation in the Factories-of-the-Future (FoF) environment. Mobile-edge computing (MEC) is thought of as a promising system for realization. However, the computation work cannot be done without reliable transmission. In this work, rather than simply investigating task offloading problem, the reliability of radio transmission is jointly considered under heterogeneous industrial IoT networks. A 2-tier MEC-cloud framework is provided, wherein the IoT mobile devices (MDs) are able to partition tasks and offload them to the MEC and the cloud server through the reliable transmission. A two-step algorithm named opportunity-cost-based offloading algorithm (OCBOA) is proposed to jointly optimize the allocation of communication and computation resources for task offloading with the minimum energy consumption and offloading failure probability. The experiments show that our low-complexity algorithm outperforms the other heuristic algorithms on resource allocation while satisfying the QoS requirements of the MDs.
Pushing Services to the Edge Using a Stateful Programmable Dataplane

Offloading to the edge a subset of the cloud services requested by users is a very appealing solution to reduce the bandwidth pressure, minimize latency and improve the overall quality of experience of mobile users. Achieving this goal is technically challenging, since the network functionalities needed to manage this offloading are not trivial, and present significant requirements in terms of scalability and speed. We propose to realize these network functionalities directly in the dataplane, exploiting the characteristic of FlowBlaze, a novel stateful programmable dataplane. Furthermore, we show how the network functions for the traffic offload can be easily expressed using an ad-hoc domain specific language developed for the description of per-flow stateful network functions.

Multi-Access Mobile Edge Computing (MEC) is proclaimed as a key technology for reducing service processing delays in 5G networks. Caching on MEC will decrease service latency and improve data access by allowing direct content delivery through the edge without fetching content from the remote server, Caching on MEC is also deemed as an effective approach that guarantees more reachability due to proximity to end-users. This paper proposes a novel hybrid content caching replacement algorithm in MEC to increase its caching efficiency where future request references are predicted using a polynomial fit algorithm along with Lagrange interpolation. Additionally, a distributed co-operative caching algorithm to improve data access within MECs. Experimental results have shown that the proposed scheme obtains more cache hits and lesser average CPU utilization due to its selective caching approach when compared with existing traditional cache replacement algorithms.

We present a practical approach of how we can use deep learning models to improve 5G network service. We demonstrate the potential of a deep Q-network agent for solving a traffic management problem, which can be applied for optimizing the network in multi-path scenarios. We use for the demonstration a multi-path QUIC implementation and we train an agent for improving the algorithm that selects the optimal path, with results in a better utilization of the network resources.

We design and assess novel random access (RA) procedures for use in 5G radio access networks in support of machine-type applications requiring Ultra-Reliable Low-Latency Communications (URLLC). In a simulation-based performance assessment the proposed RA procedures are compared against LTE Cat-M1, the current LTE-based access technology for such applications, considering a Factory of the Future scenario and a realistic density and mix of URLLC and non-URLLC devices. As a key outcome, the most promising Two-step RA with Feedback procedure is demonstrated to be able to satisfy the 3GPP-imposed 10 ms (50 ms) latency requirement of URLLC (non-URLLC) applications in 99.9% (99.99%) of the cases, with a theoretical minimum access latency of only 5 ms.

We explore the potential of optical power delivering in multicores fibers, either using cores only for power or to share data and power delivering in the same core. A comparison between both scenarios in terms of power levels for different link lengths and number of elements required is provided. We measure the impact of high power-over-fiber signals at 1480nm on the data transmission quality in a 4-core multicore fiber. Both dedicated- and shared-core scenarios are evaluated showing negligible data traffic quality performance changes.

Federico Tonini (Università di Bologna, Italy); Carla Raffaelli (University of Bologna, Italy); Steinar Bjornstad (NTNU, Norway); David T Chen (Nokia, USA); Raimena Veisllari (TransPacket AS, Norway)
A novel packet-based adaptive mechanism for bounding delay and delay variation in 5G Ethernet fronthaul is proposed. The mechanism enables aggregation of asynchronous traffic from fronthaul links using a traffic pattern adaptation algorithm. Traffic of a first stream is added in time-gaps of a second stream. For bounding and balancing the packet delay and delay variation between the streams, the size of the required time-gap before insertion is made adaptive. Simulation results demonstrate that through suitable tuning of the algorithm parameters, packet delay and delay variation below 10 microseconds can be achieved.
Active Queue Management as Quality of Service Enabler for 5G Networks
Mikel Irazabal (Universitat Politecnica de Catalunya, Spain); Elena Lopez-Aguilera (Technical University of Catalonia (UPC), Spain); Ilker Demirkol (Universitat Politecnica de Catalunya, Spain)
5G is envisioned as the key technology for guaranteeing low-latency wireless services. Packets will be marked with QoS Flow Indicators (QFI) for different forwarding treatment. 3GPP defines the end-to-end delay limits, but leaves the QoS provisioning methods as implementation dependent. Different services with different constraints will inevitably share queues at some network entity. On the one hand, maintaining the shared queues uncongested will guarantee a rapid packet delivery to the subsequent entity. A brief sojourn time is indispensable for an on time low-latency priority traffic delivery. On the other hand, if shared queues are maintained undersized, throughput will be squandered. In this paper, we propose the use of AQM techniques in 5G networks to guarantee delay limits of QoS flows. Through the evaluation of realistic delay-sensitive and background traffic, we compare different possible solutions. We show that AQM mechanisms together with limited queues, maintain the system uncongested, which reduces drastically the delay, while effectively achieving the maximum possible throughput.

Groups of users, sometimes referred to as clusters, have been exploited in several works to enhance wireless communications. Leveraging on previous ideas, the main goal of this paper is to take advantage of vehicle grouping in order to reduce uplink signaling in fifth generation (5G) vehicular communications. Several schemes to reduce uplink signaling are proposed and particularized in two specific 5G uses cases: the reporting of Channel Busy Ratio (CBR), and the reporting of beam measurements in beam management procedures. The achieved signaling reduction is analytically evaluated in an example of urban scenario with high vehicle densities for different group sizes. The signaling load can be reduced in such scenario between 10 and 40 times for the CBR, and between 3 and 7 times for the beam measurements.

Rule-Based Translation of Application-Level QoS Constraints into SDN Configurations for the IoT
Jan Seeger (Technical University Munich & Siemens AG, Germany); Arne Bröring (Siemens AG, Germany); Marc-Oliver Pahl (Technical University of Munich, Germany); Ermin Sakic (Siemens AG, Germany)
In this paper, we propose an approach for the automated translation of application-level requirements regarding the logical workflow and its QoS into a configuration of the underlying network substrate. Our goal is to facilitate the integration of QoS constraints in the development of industrial IoT applications to make them more reliable. We follow an approach based on two semantic models: The first model allows to design the workflow of an IoT application and to express application-level QoS requirements on its interactions. The second model captures the configuration of a network and can be used as input to a north-bound interface of an SDN controller. Finally, we make use of rule-based semantic reasoning to automatically translate from the application requirements into SDN parameters.

After more than ten years of research and development, Software-Defined Networking (SDN) and Network Function Virtualization (NFV) are finally going mainstream. The fifth generation telecommunication standard (5G) will make use of novel technologies to create increasingly intelligent and autonomous networks. The METRO-HAUL project proposes an advanced SDN/NFV metro-area infrastructure based on an optical backbone interconnecting edge-computing nodes, to support 5G and advanced services. In this work, we present the METRO-HAUL planning tool subsystem that aims to optimize network resources from two different perspectives: off-line network design and on-line resource allocation. Off-line network design algorithms are mainly devoted to capacity planning. Once network infrastructure is in production stages and operational, on-line resource allocation takes into account flows generated by end-user-oriented services that have different requirements in terms of bandwidth, delay, QoS and set of VNFs to be traversed. Through the paper, we describe the components inside the planning tool, which compose a framework that enables intelligent optimization algorithms based on Machine Learning (ML) to assist the control plane in taking strategic decisions. The proposed framework aims to guarantee a fair behavior towards past, current and future requests as network resource allocation decisions are assisted with ML approaches. Additionally, interaction schemes are proposed between the open-source JAVA-based Net2Plan tool, ML libraries and algorithms in Python easing algorithm development and prototyping for rapid interaction with SDN/NFV control and orchestration modules.
Network Optimization as a Service with Net2Plan
Miquel Garrich, César San Nicolás Martínez and Francisco-Javier Moreno-Muro (Universidad Politécnica de Cartagena, Spain); Maria Victoria Bueno (UPCT, Spain); Pablo Pavon-Marino (Technical University of Cartagena, Spain)
Carrier-grade telecommunication infrastructure must support an ever-increasing traffic volume and dynamicity in operationally-complex networks characterized by multiple domains, multiple technologies and equipment from multiple vendors. At the same time, the advent of Software-Defined Networking (SDN) and Network Function Virtualization (NFV) technologies create transport ecosystems with unprecedented network control and resource dynamicity capabilities. In this context, network optimization is essential to efficiently employ network resources, relying whenever possible on automated procedures and exploiting open application programmatic interfaces (APIs) inherent of SDN/NFV ecosystems. Automated network optimization procedures on top of network controllers promote a client layer of third-party applications that enable optimization-as-a-service (OaaS) business opportunities. In this paper, we present a network OaaS framework built as an extension of the Net2Plan open-source network planning tool. The proposed framework is based on a classical client-server architecture, and through a REST-based API, holders of network infrastructures (i.e. client role) may request the resolution of a network resource allocation problem through the execution of an algorithmic technique. Thus, third-party players can focus on the development of optimization algorithms (i.e. server role) while potentially providing high-performance computing (HPC) capabilities for their execution. Through the paper, we detail the workflow of the proposed OaaS, illustrate its usage with several use-cases and discuss its applicability in different scenarios.
Towards Cross-Layer Optimization of Virtualized Radio Access Networks
Behnam Rouzbehani (Instituto Superior Técnico & GROW - Group for Research on Wireless, INOV - INESC Inovação, Portugal); Vladimir Marbukh (National Institute of Standards and Technology, USA); Kamran Sayrafian (NIST, USA); Luis M. Correia (IST/INESC-ID - University of Lisbon & INESC, Portugal)
This paper proposes an approach to cross-layer optimization of virtualized Radio Access Network resources in future mobile communications. Assuming that the Virtual Network Operators (VNOs) guarantee contracted Service Level Agreements (SLAs) with the users, the proposed approach uses weighted proportional fairness as a basis for allocation of the remaining capacity. This allocation is achieved by a distributed, pricing-based solution to a two-layer convex optimization problem. Through this mechanism, some of the key functionalities of the centralized virtualization platform are transferred to the individual VNOs and users. This allows for a drastic reduction in the complexity of the system management compared to the previously proposed centralized approaches. Therefore, it leads to a much more scalable design for dense network deployments with real-time applications. Another advantage of the proposed distributed cross-layer optimization is the enhanced level of isolation among different VNOs. The proposed approach is evaluated by simulating a scenario with 3 types of VNOs and differentiated SLAs sharing radio resources from an underlying physical heterogeneous network. Results for the 4 types of service classes confirm that given sufficient aggregate capacity, all SLAs are satisfied, the entire aggregated capacity is utilized, and the residual available capacity is shared among the users proportionally fair.
A Fingerprint-based Bloom Filter with DeletionCapabilities
Minseok Kwon and Vijay Shankar (Rochester Institute of Technology, USA); Salvatore Pontarelli (National Inter-University Consortium for Telecommunications (CNIT), Italy); Pedro Reviriego (University Carlos III of Madrid, Spain)
One drawback of Bloom filters is the inability to delete items due to hash collisions. Counting Bloom filters address this drawback using counters at the expense of increased filter size. Other alternatives like the Deletable Bloom Filter (DlBF) or the Ternary Bloom Filter (TBF) have been proposed to maintain a small filter size while supporting deletions of elements with some probability. These structures offer different trade-offs between deletability, false positive rate and filter size. In this paper, we propose a new filter called the D-FP (Deletable Fingerprint) Bloom filter that stores two-bit fingerprints, instead of a single bit or a counter, that can indicate whether the item can be deleted. By using the fingerprints, the D-FP Bloom filter provides lower false positive rates than the TBF at low filter occupancies and better deletability than the DlBF thus providing more options to desginers that want to trade-off both parameters. In addition to presenting the D-FP Bloom filter, this paper also presents an analysis of the effects of deletions on the performance of the DlBF and TBF. Finally, as a result of the simulations, we observe that the original analytical estimate for the deletable probability of DlBF tends to overestimate the probability.

This paper presents the novel SDN/NFV 5G fronthaul network scenarios deployed in the blueSPACE project. blueSPACE envisions the upgrade of the fronthaul network to include optical SDM transmission for further increasing the network capacity. One of the novelties is the introduction of ARoF transceivers to reduce the 5G fronthaul bandwidth requirements, in addition to the DRoF solutions that are used for the 4G fronthaul interface and the 3GPP's NGFI. Moreover, ARoF transceivers enable to develop optical beamforming technologies for beam steering and multi-beam transmission. Finally, power of fiber solutions to remotely feed small cells are also considered.

Miliou and Nikos Pleros (Aristotle University of Thessaloniki, Greece)
Centralized Radio Access Network (C-RAN) comprises one of the main technologies for high capacity and low latency fronthauling in 5G networks. In this paper, we propose and evaluate an optical fronthaul 5G C-RAN architecture that targets to meet the bandwidth, latency and energy requirements of high traffic hot-spot areas. The proposed architecture employs Intermediate-Frequency-over-Fiber (IFoF) signal generation by Photonic Integrated Circuit (PIC) Wavelength Division Multiplexing (WDM) optical transmitters at the Base-Band Unit (BBU), while a novel design of Reconfigurable Optical Add-Drop Multiplexers (ROADMs) is used at the Remote Radio Head (RRH) site. An aggregate capacity up to 96 Gb/s has been reported by employing two WDM links with 4-band Orthogonal Frequency Division Multiplexing (OFDM) 64-QAM 0.5 Gbaud signals, showing error vector magnitude performance below the acceptable 8% limit. The physical layer evaluation of the proposed fronthaul is also extended with the evaluation of the network throughput and mean packet delay latency, using a Medium Transparent-Medium Access Control (MT-MAC) protocol, which employs gated service indicating latencies below 10ms.

Fronthaul Links Based on Analog Radio over Fiber
Diego Perez-Galacho, Demetrio Sartiano and Salvador Sales (Universitat Politecnica de Valencia, Spain)
Current Information and Communication Technology systems are nowadays close to a ´capacity crunch´ as global IP traffic increases. This problem will be particularly important in the Mobile Fronthaul. This scenario is driving the search for new multiplexing techniques that could solve short-term bandwidth problems and provide a good scalability in the long-term view. Space division multiplexing in the optical domain is currently considered as the best option to provide a new degree of freedom to scale the bandwidth of optical communication systems. On top of using space division multiplexing a further increase in the spectral efficiency of the mobile fronthaul can be achieved using a centralized radio access network based on analog radio over fiber. In this work, we address the experimental demonstration of the transportation of 5G New Radio signals on fronthaul optical links using Analog Radio over Fiber.

The fifth generation (5G) mobile systems can be considered the way to ubiquitous Internet, pervasive computing paradigm, and a revolution in industries like automotive, media and entertainment, and eHealth. New 5G fronthaul systems based on centralized radio access networks will eventually use technology enablers such as reconfigurable optical add-drop multiplexers, space-division multiplexing, ribbon fibers, software-defined networking, multiple-input multiple-output signaling, analog radio-over-fiber signals, and beamforming. In this context, this paper addresses the principal technology enablers of the 5G PPP phase 2 projects blueSPACE and 5G-PHOS and their potential interoperability. The convergence of 5G key-performance indicators (KPIs) along with methodologies and usage scenarios is also addressed. Furthermore, the 2020 European championship is perceived here as a unique opportunity to leverage a 5G pan-European trial platform. The technologies developed in both projects are seen as potential candidates for next generation mobile networks, where ultra-low latency, energy efficiency, and millions of connected devices are major network KPIs requirements.

Comparison of Optimization Methods for Aerial Base Station Placement with Users Mobility
Danaisy Prado, Saul Inca, David Martín-Sacristán and Jose F Monserrat (Universitat Politècnica de València, iTEAM Research Institute)
Aerial base stations have been recently considered in the deployment of wireless networks. Finding the optimal position for one or multiple aerial base stations is a complex problem tackled by several works. However, just a few works consider the mobility of the users which makes necessary an online optimization to follow the changes in the scenario where the optimization is performed. This paper deals with the online optimization of an aerial base station placement considering different types of users mobility and three algorithms: a Q-learning technique, a Gradient-based solution and a Greedy-search solution. Our objective is to minimize in an urban environment the path loss of the user at street level with the highest path loss. Simulation results show that the performance of the three methods is similar when a high number of users move randomly and uniformly around the scenario under test. Nevertheless, in some situations when the number of users is reduced or when the users move together in a similar direction, both Gradient and Greedy algorithms present a significantly better performance than the Q-learning method.

Providing broadband Internet access in remote areas have been a challenge to any terrestrial wireless network. The high cost of spectrum license and the limited coverage of current technologies have imposed a prohibitive operational cost for remote areas wireless networks. 5G-RANGE project proposes an innovative physical layer (PHY) and medium access control layer (MAC) layers to opportunistically exploit TV white spaces (TVWS) while providing high throughput in a large coverage area. This paper presents the first field test results based on this new technology. The field trial was performed with the 5G-RANGE project transceiver, implemented for real-time operation over a software-defined radio (SDR) platform. The 2x2 multiple-input multiple-output (MIMO) Generalized Frequency Division Multiplexing (GFDM) system operates in 700 MHz using two adjacent Ultra High Frequency (UHF) TV channels. The landscape in the region of the field trial is predominantly composed of hills. The main goal of the field test was to determine the throughput and coverage that the 5G-RANGE transceiver can achieve under real conditions. The results show that a high data rate can be achieved with low bit error rate (BER) at distances up to 50 km distant from the base station (BS).

Edge computing that leverages cloud resources to the proximity of user devices is seen as the future infrastructure for distributed applications. However, developing and deploying edge applications, that rely on cellular networks, is burdensome. Such network infrastructures are often based on proprietary components, each with unique programming abstractions and interfaces. To facilitate straightforward deployment of edge applications, we introduce open-source software (OSS) based radio access network (RAN) on over-the-air (OTA) commercial spectrum with Development Operations (DevOps) capabilities. OSS allows software modifications and integrations of the system components, e.g., Evolved Packet Core (EPC) and edge hosts running applications, required for new data pipelines and optimizations not addressed in standardization. Such an OSS infrastructure enables further research and prototyping of novel end-user applications in an environment familiar to software engineers without telecommunications background. We evaluated the presented infrastructure with end-to-end (E2E) OTA testing, resulting in 7.5MB/s throughput and latency of 21ms, which shows that the presented infrastructure provides low latency for edge applications.

Mobile operators have already started their 5G network deployment and next generation user terminals commercial release is planned for the upcoming months. Knowing the future network system performance and capabilities seem to be key in order to have proper planning strategies. In this paper we present some field test trials for the latest release of 4G, which have lots of similarities with the forthcoming mobile broadband standard. Results for urban drive tests are presented too. We also bring some pathloss simulation based on modern channel models that matches the results obtained in the real scenarios. Error is measured to have some insights about the utility and accuracy of the pathloss models when comparison with specific scenarios is made. Some final brainstorming for future work with 5G network and concluding remarks are proposed.

Pedro Merino (University of Malaga, Spain); Ivan Gonzalez Muriel (University of Malaga & MORSE Research Group, Spain); Alvaro Martin (University of Màlaga, Spain)
Due to the exponential growth in data usage that mobile networks have been experiencing in the past years, improvements in the performance and capacity of these networks have become key for the next mobile generation. Traffic aggregation at different layers in the radio interface increases the bandwidth and reliability for specific users. A promising aggregation approach for future networks is LWIP, which consists of LTE-WLAN aggregation at the IP level, just above the PDCP layer. It allows integrating WiFi with the LTE access network for the user plane data, making use of the legacy WLAN infrastructure. This paper presents a testbed where researchers can test different aggregation policies with real LTE and WiFi traffic making use of our own LWIP implementation.
Spectrum Coordination for Disaggregated Ultra Dense Heterogeneous 5G Networks
Nikos Makris (University of Thessaly & CERTH, Greece); Panagiotis Karamichailidis, Christos Zarafetas and Thanasis Korakis (University of Thessaly, Greece)
Cloud-RAN paves the way for flexible network management and control in the upcoming 5G and beyond networks. The base station disaggregation in different functional elements facilitates the incorporation of heterogeneous technologies in the user access network (e.g. 5G-NR, LTE, WiFi). Network densification and integration of heterogeneous technologies enables larger network capacity through the aggregation of multiple links, thus assisting the transition from the existing network infrastructure to innovative 5G networks. Nevertheless, as Ultra-Dense Heterogeneous Networks may operate in the same wireless spectrum, their performance potential may be hindered through the operation in overlapping frequencies. Thus, efficient coordination is required between the involved heterogeneous technologies. In this work, we consider a disaggregated base station setup, based on the current standards for 5G-NR, with capabilities to incorporate heterogeneous technologies for serving the UEs. We develop signalling between the heterogeneous Distributed Units and the Central Unit, and apply a spectrum coordination algorithm for optimal use of the wireless spectrum. We use OpenAirInterface as our development platform, and evaluate our results in a real testbed setup.

The lack of interoperability between the IoT platforms has led to a fragmented environment, where the users and the society as a whole suffer from lock-ins, worse privacy, and reduced functionality. This paper presents SOFIE, a solution for federating the existing IoT platforms in an open and secure manner using distributed ledger technologies (DLTs) and without requiring modifications to the IoT platforms, and describes how SOFIE is used to enable two complex real life pilots: food supply chain tracking from field to fork and electricity distribution grid balancing with electrical vehicle (EV) charging. SOFIE's main contribution is to provide interoperability between IoT systems while also enabling new functionality and business models.

This paper proposes areas of improvement for Low Power Wide Area (LPWA) solutions. After recalling the rationale of these systems, it summarizes the main challenges of existing solutions and proposes various improvements at PHY and MAC layer that were investigated in context of the EPHYL project. NB-IoT and LORA were mostly considered in the analysis of existing techniques, while proposals for improvement address both waveform design and resource allocation strategy. We propose as well introduction of new paradigm such as network coding to benefit of the sparse characteristic of some LPWA use cases. Some of the proposals are validated experimentally in the FIT/CorteXlab environment, offering to the research community a framework to experiment and compare their improvements of LPWA systems.
Assignment of IoT Nodes to Edge Computing Devices in Internet of Things
Madhu Perkin and S Mini (National Institute of Technology Goa, India)
The Internet of Things (IoT) is a concept of computing that describes the idea of connecting physical objects to the internet. In general, IoT is a network of devices every object is connected through internet or some non-internet oriented connections like Bluetooth, ZigBee, etc. It features an IP address for Internet connectivity, and the communication occurs between these objects and other Internet-enabled devices and systems. IoT is typically used to monitor real time environment and hence generates huge volume of data. The cloud is an attractive IoT data storage option due to its cost and capacity benefits. But for time critical applications, it may be a challenge. Edge computing is a solution to this problem. Edge computing refers to computing data near to where it is created, at the edge of the network, instead of a central point far away. The computed and processed data is then sent to cloud. In order to achieve this, IoT nodes have to connect to the Edge computing devices. However, it is a challenge to identify the Edge Computing Device (ECD) to which each IoT node should connect. This work describes an approach to assign the IoT nodes to the ECDs based on a dynamic threshold value and a meta heuristic is applied to schedule the tasks so that the completion time is minimum. The results based on the simulation show the advantages of the proposed work.
Towards Democratizing E-Health Under Constrained ICT Infrastructure Through 'A- REaLiST' Solution
Abhijan Bhattacharyya (Tata Consultancy Services Ltd., India); Suvrat Agrawal, Hemant Kumar Rath and Arpan Pal (Tata Consultancy Services, India)
The primary need for mass e-health service is, the remote doctor should be able to examine the patient through video communication over public Information and Communication Technology (ICT) infrastructure. However, poor ICT infrastructure creates a key obstacle for rural India due to low bandwidth and intermittent Internet connectivity. This paper critically examines the state of the public ICT infrastructure in India and proposes an end-to-end solution such that the Quality of Experience (QoE) for remote visual examination can be ensured over IP connectivity even in a 2G network. We extend previously proposed video streaming solution for Internet of Things (IoT) called A-REaLiST (Adaptive-RESTful Real time Streaming for Things). Thus we extend the design principles of IoT communication in order to achieve an acceptable QoE by effectively harnessing the latent potential in the existing infrastructure. Efficacy of the solution is determined through benchmarking experiments under realistic network conditions and comparing with existing state of the art.
WearIoT - Wearable IoT Human Emergency System
Miriam Batista, Rodrigo L. Cortesão and Pedro Sebastião (ISCTE-IUL, Portugal)
The evolution of technologies gives rise to new concepts in many areas. Health problems are increasing as the world population. Global aging is increasing as well as care costs are also rising. It is increasingly necessary to improve precocious disease detection and medical intervention. Wearable monitoring systems, along with wireless communications, form the basis of an emerging class of sensor networks. These information technologies enable the early detection of abnormal conditions and help in their prevention. The goal is to create one of these systems composed by a network of sensors that is implemented in a jacket through conductive wires with connected sensors. In contact with the human body it has the function of doing several readings, such as body temperature, heartbeat, among others. Another goal is to detect user falls. The detection of falls is increasingly important for the user, as it is a situation that can endanger peoples health. For the development of this concept, Mobile Communications and the Global Positioning System are used. The first is a technology that allows to create emergency calls in response to system alarms, the second indicates the geographical location. To complement the system there is an online platform that registers the position of the user as well as his data. There is also an alert area in which the user can check his alarming values. In case of emergency the system contacts the emergency services or in special cases help can be obtained through an UAV.

Doubly Constrained Underlay Cognitive Radio System: Optimization and Analysis
Aniruddha Paturkar and Vibhuti Goel (BITS Pilani, Rajasthan, India); B. Sainath (BITS Pilani, India)
In this paper, we consider a doubly constrained underlay cognitive radio (CR) system. In it, a secondary user (SU) transmitter (Tx) is subject to average interference constraint, and spectral efficiency constraint. For the underlay system, we investigate both average energy efficiency and average spectral efficiency. Specifically, we develop an algorithm that determines the suboptimal operating point of transmit power with which the SU-Tx must operate for maximum energy efficiency. We derive an analytical expression for the fading-averaged spectral efficiency assuming Rayleigh fading with path loss and shadowing. To validate the analytical results, we simulate the model in two different platforms and investigate system performance. The analysis that we present are useful for constrained cognitive radio systems and networks.

A modulation recognition method based on a simple convolutional neural network (CNN) architecture is assessed through classification of synthetic baseband signals in the presence of a second known signal source. The complexity and adaptability of CNNs is leveraged so as to forgo statistical feature extraction procedures and efficiently classify based on raw signals or their modified forms. Experimentation for the optimisation of the model's behaviour is carried out through an attempt to exploit the a priori information of the secondary source modulation scheme. Simulation results show that the proposed modifications demonstrate a positive effect upon general performance.
Optimal Reserved Resources to Ensure the Repetitions in Ultra-Reliable Low-Latency Communication Uplink Grant-free Transmission
Trung-Kien Le (EURECOM, France); Umer Salim (TCL, France); Florian Kaltenberger (Eurecom, France)
To meet the strict requirements of Ultra-Reliable Low-Latency Communication in the uplink, grant-free uplink transmission has been specified, allowing the UE to transmit data in a random-access fashion without first transmitting a scheduling request and then waiting for a uplink grant from the gNB. To further increase the reliability, these grant-free uplink transmissions can be repeated without waiting for HARQ feedback from the gNB. However, these repetitions have to happen within a certain interval to avoid a confusion in HARQ IDs of different HARQ processes. When a UE starts transmitting late in the interval, it, therefore, can not exploit all the possible repetitions and thus reliability and latency decrease. In this paper, a scheme based on reserved resources is proposed to ensure the number of repetitions in a specific period. The size of each reserved resource is optimized depending on its position so as to reduce resource consumption. The scheme evaluated by theoretical analysis and numerical results shows its benefits to system performance.

In time division duplexing based mobile networks, under certain atmospheric ducting conditions, the uplink reception may be interfered by the downlink transmissions of remote base-stations (BSs) located hundreds of kilometers away. This paper addresses such remote interference problem in 5G new radio (NR) macro deployment context. Specifically, two potential reference signal (RS) designs for remote interference management (RIM) are described, together with receiver detection processing framework, to efficiently detect the interference due to multiple remote aggressor base-stations at a victim BS. The first signal structure, denoted as the one OFDM symbol (1OS) based RIM-RS, is building on the channel state information reference signals (CSI-RS) of 5G NR. The second candidate is referred to as the two OFDM symbol (2OS) based RIM-RS design, and builds on the design principles of LTE RIM-RS. The considered RIM-RS solutions are extensively analyzed and compared, with different parameterizations, in several realistic interference scenarios. The obtained results show that the 2OS RS design provides better RIM performance in scenarios where the number of interfering BSs is small. However, when the number of interfering BSs increases, the 1OS RS design starts to outperform the 2OS based approach. Additionally, it is shown that the 1OS RIM-RS provides smaller overhead and can be frequency multiplexed with the physical downlink shared channel.

Diogo Sequeira Martins (University of Lisbon - Instituto Superior Técnico & Vodafone Portugal, Portugal); Luis M. Correia (IST/INESC-ID - University of Lisbon & INESC, Portugal); Ahmed Alsohaily and Elvino Silveira Sousa (University of Toronto, Canada)
The ability to accommodate the contrasting requirements of extended coverage, enhanced capacity and reduced deployment costs has led to the adoption of Two-Tier connectivity structures, in which secondary nodes connect users' terminals to base stations, as a promising design direction for contemporary cellular communications systems. This paper considers a Two-Tier Cellular Network employing fixed secondary nodes and introduces enhanced channel estimation and resource allocation procedures that exploit lower channel variation rates, along with the ability to use larger antenna arrays at these nodes to achieve substantial performance gains. Based on data measured from a live LTE-Advanced network, the expected average throughput gains when connecting a single secondary node varied between 10.2% and 65.0%. Furthermore, when emulating the deployment of five secondary nodes under the Round Robin, Best Channel Quality Index and Proportional Fair scheduling algorithms, one anticipates average throughput gains of 64.0%, 41.2% and 128.5%, respectively, while resource allocation fairness is expected to improve by 28.9%, 80.2% and 24.1%, respectively.
Ultra-reliable V2X Communication: On the Value of User Cooperation in the Sidelink
Malte Schellmann (Huawei Technologies German Research Center, Germany); Tapisha Soni (Huawei European Research Center & Germany, Germany)
The 5G system and its service for ultra-reliable low latency communication are considered key enablers for enhanced use cases of vehicular-to-anything (V2X) communications, paving the way towards automated and autonomous driving. Reliability in a wireless link can be improved substantially if a large degree of channel diversity can be exploited. The V2X sidelink can offer numerous independent communication links between a target car and its neighbours, and the diversity offered by these links can be made available by cooperative retransmission of data packets received from a prior multi-cast transmission. This paper elaborates on the value of user cooperation in the sidelink for attaining ultra-reliability in V2X communications by analyzing the reliability gains in dependence of the number of cooperating users and for considering an additional retransmission, if the latency budget allows. Analysis reveals that the attainable gains scale with up to one order of magnitude per cooperative user. If strong differences in the power per link due to path-loss effects are taken into account, gains are obviously degrading, though the degradation can be kept at a moderate level if an additional retransmission with appropriate user grouping is considered.

Elastic Slice-Aware Radio Resource Management with AI-Traffic Prediction
Sina Khatibi (NOMOR Research GmbH, Germany); Alba Jano (Nomor Research GmbH, Germany)
Network virtualisation and network slicing are the two essential innovations in the next generation of mobile networks also known as the 5G network. Based on these innovations, multiple network slices with different requirements and objectives can share the same physical infrastructure. The techniques to efficiently allocate the available radio resources to different slices based on their requirements and their priority, also known as inter-slice radio resource management, has been the subject of many studies. The formerly proposed algorithms either assume the slices request maximum contracted data rates or they react passively as the demands arrive. This paper proposed to use Artificial Intelligence (AI) approaches to learn the pattern of the traffic demand of each network slices and predict the demands in the next decision interval. Based on the prediction of the slices' demands, a novel model for elastic inter-slice radio resource management has been proposed to increase the multiplexing gain while not compromising the quality of offered connectivity services to the slices. The proposed model has been evaluated using a practical scenario. The numeric results show that while the performance of the model under full demand is similar to former models, its elastic resource management enables more efficient resource allocation when the traffic demands vary during the time.
C-RAN Employing xRAN Functional Split: Complexity Analysis for 5G NR Remote Radio Unit
Jay Kant Chaudhary and Atul Kumar (Technische Universität Dresden, Germany); Jens Bartelt (Airrays, Germany); Gerhard P. Fettweis (Technische Universität Dresden, Germany)
Fronthaul (FH) bandwidth in C-RAN can be significantly reduced with an appropriate functional split by offloading more signal processing functionalities to the remote radio unit (RRU). However, this not only reduces the acclaimed centralization benefits but also increases the complexity of the RRU. Considering the practical aspects such as size, weight, power consumption, it is often desirable to make RRU as simple, yet efficient, as possible. In this paper, we compute the computational requirement of the RRU with 5G New Radio (NR) considering functional split 7.2 as recently standardized by the xRAN Forum. C-RAN with mix numerology allows to support a wide range of scenario and use-case specific requirements. In addition, we compare suitability in terms of efficiency and flexibility of the RRU being implemented using either FPGA or GPP considering their computational requirement. Based on the complexity analysis, we calculate the required number of the FPGA or GPP to handle the complexity of the RRU. We show that FPGA is more feasible option compared to x86 in terms of form factor and power consumption particularly for rooftop mounted RRU.
Edge Sectors Detection in Mobile Communications Networks
Omar Kaddoura (Ericsson & University of Malaga, Spain); Inmaculada Serrano and Juan Sánchez-Sánchez (Ericsson, Spain); Raquel Barco (University of Malaga, Spain)
This paper proposes a method to detect edge sectors in mobile communication networks. This detection has applications such as identifying results of geolocation techniques presenting low accuracy or reducing false positives in troubleshooting algorithms. On the way to achieve the desired goal, the method also finds the nodes which are part of convex and concave regions in the contour of the network. The proposed method consists of three phases: independent areas identification, contour nodes detection and edge sectors detection. All these phases can be parameterized according to the pursued objective. Experiments have been carried out to prove the goodness of the proposed method to detect sectors in which location techniques like Received Signal Strength used to estimate the location of mobile users present high error figures. Results obtained prove the validity of the proposed method.

This work presents essential aspects of 5G system level simulator for enabling advanced component validations and optimizations. System level simulations in the 5G era, consider demanding use cases with high load and very limited latency in order to cover services such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC) and ultra-reliable low-latency communications (URLLC). As such, appropriate configuration, environment and network models need to be defined in order to proceed to performance evaluation. The system-level simulation platform is a discrete event simulation environment for the simulation of heterogeneous networks which is extended with new features to support the new functionalities of 5G. To show the potential of this simulation tool, in this work, a framework for multi-connectivity management has been integrated and assessed in a load-imbalanced scenario. Simulation results show how a proper assignment of component carriers (CCs) in this situation allows increasing the users' throughput by up to a 60% when compared to a simple received power scheme for link management.
Multi-Numerology Based Resource Allocation for Reducing Average Scheduling Latencies for 5G NR Wireless Networks
Tanmoy Bag and Sharva Garg (Ilmenau University of Technology, Germany); Zubair Shaik (Technische Universität Ilmenau, Germany); Andreas Mitschele-Thiel (Ilmenau University of Technology, Germany)
The introduction of 5G New Radio (NR) promises flexibility and adaptability to cater a wide variety of services. One of the key ingredients for achieving such requirements is the employment of multiple numerologies. This versatility brings along with it some complexity as well in terms of resource allocation using multiplexed non-orthogonal numerologies. Another key enabler is the concept of Shortened TTI/ Mini-slots for addressing low latency applications. In this paper, we propose a dynamic resource allocation scheme to reduce the average scheduling latencies in a network using multiple numerologies in conjunction with mini-slots. A system level simulation has been conducted to compare different nominated combinations of numerologies (with mini-slots) and service requests and it has been observed that with a minor compromise of minimum achievable scheduling latency for high priority requests, a significant reduction of average scheduling latency is attained considering all types of diverse service requests with different priorities.
Profit-Based Radio Access Network Slicing for Multi-tenant 5G Networks
Jordi Pérez-Romero (Universitat Politècnica de Catalunya (UPC), Spain); Oriol Sallent, Ramon Ferrús and Ramon Agustí (Universitat Politècnica de Catalunya, Spain)
Network slicing is a key capability of 5G networks that facilitates the provision of multi-tenancy by allocating different slices to the tenants that share a certain infrastructure according to specific Service Level Agreements (SLAs). In this context, this paper focuses on radio admission control as the function that controls the amount of radio resources assigned to the different tenants in a 5G radio access network. Specifically, a novel approach is proposed that includes profit-related metrics in the decision-making process, accounting for the additional extra incomes that can be obtained by sporadically granting additional capacity beyond the SLA level and for the penalties incurred due to potential SLA breaches. The proposed approach is evaluated by means of simulations to assess its benefits in terms of achieved profit and throughput.

Beyond 5G and Artificial Intelligence
Room: Auditorium 2


Panagiotis Demestichas (University of Piraeus, Greece)

Motivation and Background:

This panel will investigate the tight coupling of the new connectivity generation and the digital transformation with the advent of AI. 5G and future connectivity infrastructures will offer unprecedented performance levels. Gradually, through successive standards versions, new services will be enabled. These services will transform the way end-users live, corporations conduct business, and governments operate. This will happen in a direct manner (e.g., enhanced eMBB/URLLC-powered applications offered to end users) or indirectly, e.g., by providing data, in a timely and reliable manner, to advanced AI mechanisms, which are essential for the provision of vertical services.

Potential benefits from the introduction of intelligence in the system could aid network management and optimization, increase spectrum efficiency and improve QoS/QoE; however, AI will also affect the design of new architectures beyond 5G resulting in many uncharted scientific territories.

From a different perspective, new businesses and the sustainability of current ones call for more intelligence in the network infrastructure. Aspects like AI and Machine/Deep Learning seem to open new business opportunities and to pave the way for areas in need of research work.
