Abstract: Software defined wireless networking (SDWN) is an emerging communications paradigm and an essential technology in the next-generation 5G systems. In SDWN, software oriented design, the separation of the data and control planes, and network virtualization, can unfold numerous advantages to manage network complexity and dynamics. In the tutorial, we will introduce the key concepts related to Software Defined Networks (SDN) and SDWN. Then, we will mainly focus on exploring software designed principle in various wireless networks, including software defined device-to-device communications, software defined sensor networks, software defined wireless mesh networks, and software defined vehicular networks.

TS02. Massive MIMO: Fundamentals and Recent Developments

Room: 233M
Presenters:
  • Erik G. Larsson, Linkoping University, Sweden
  • Thomas L. Marzetta, Nokia Bell Labs, USA
Abstract: Massive MIMO is the currently most compelling sub-6 GHz wireless access technology for 5G. The key concept is to equip base stations with arrays of many antennas, which are used to serve many terminals simultaneously, in the same time-frequency resource.  Massive MIMO provides uniformly good service to wireless terminals in high-mobility environments.  Since its inception about a decade ago, it has evolved from a wild academic idea to one of the primary research topics in the wireless communications community, as well as a main work item in 5G standardization. This tutorial will cover the fundamental theory behind this technology, much based on the recent Cambridge text Fundamentals of Massive MIMO, along with some more recent results.
 

TS03. Fog Computing and Networking: A New Paradigm for 5G and IoT Applications

Room: 237M
Presenters:
  • Tao Zhang, CISCO Systems, USA
  • Tony Quek, Singapore University of Technology and Design, Singapore
  • Jianwei Huang, Chinese University of Hong Kong, China

Abstract: A key trend in networking during the past decade is to push various capabilities, such as computation, control, and storage, to the cloud. Such a cloud-centric architecture is not suitable for satisfying the demands of many delay-sensitive applications in 5G and IoT. An emerging alternative paradigm is the fog computing, where the cloud descends to the network edge and diffuses among the client devices in both mobile and wireline networks. This tutorial will provide an overview and discuss the  technical and economic challenges of fog computing and networking, both in terms of industry practice and academic research.

Now, upcoming 5G services demand high reliability and very precise accuracy in the cm-range. In this tutorial, we will present the fundamentals of cellular localization, location-awareness in cellular communication systems, the evolution of cellular localization standards from 1G to 4G, and the new localization trends from 4G towards 5G, in order to fulfill future applications.

Non-orthogonal multiple access (NOMA) has recently received considerable attention as a promising candidate for 5G multiple access. Recent demonstrations by industry show that the use of NOMA can significantly improve the spectral efficiency of mobile networks. In this tutorial, we will provide a progress review for NOMA, including the design of multi-input multi-output (MIMO) and cooperative NOMA, the application of NOMA in millimeter-wave (mmWave) networks, hybrid NOMA, resource allocation for NOMA, and the impact of practical constraints on the performance of NOMA.

TS11. Rate-Splitting for MIMO Wireless Networks: A Promising PHY-Layer Strategy for 5G

Room: 223M
Presenters:
  • Bruno Clerkx, Imperial College London, UK
  • Hamdi Joudeh, Imperial College London, UK
Abstract: The fundamental bottleneck towards enormous spectral efficiencies in MIMO networks lies in huge demands for accurate channel state information at the transmitter (CSIT), essential for multiuser interference management. Traditional approaches strive to apply techniques designed for perfect CSIT to scenarios with imperfect CSIT. We depart from this tradition and introduce the audience to rate splitting (RS), where common messages decoded by multiple users are transmitted alongside conventional private messages decoded by their corresponding users. RS provides significant benefits in terms of spectral efficiencies, reliability and CSI feedback overhead reduction over conventional strategies in a wide range of applications and scenarios.

TT01. On-Line Learning for Real-Time Dynamic Spectrum Access:  From Theory to Practice

Room: 235M
Presenters:
  • Christophe Moy, CentraleSupelec, France
  • Emilie Kaufmann, Université de Lille, France
Abstract: This tutorial covers both theoretical and implementation aspects of on-line machine learning for dynamic spectrum access in order to solve spectrum scarcity issue. We show that most dynamic solution, e.g. Opportunistic Spectrum Access (OSA), can be modelled as a multi-armed bandit (MAB) problem. We then derive mathematical solutions: (i) frequentist solutions, such as UCB and KL-UCB; (ii) Bayesian solutions, such as Bayes UCB and Thompson Sampling. A demonstrator running reinforcement learning algorithms on real radio signals confirms the mathematical derivations in several contexts of both i.i.d. and Markovian spectrum load, with mono and multi-users scenarii for OSA.

TT03. Challenges and Solutions for Networking in the Millimeter-wave Band

Room: 211
Presenters:
  • Carlo Fischione, KTH Royal Institute of Technology, Sweden
  • Hossein Shokri-Ghadikolaei, KTH Royal Institute of Technology,  Sweden
Abstract: The tutorial highlights the most prominent networking challenges for millimeter-wave (mm-wave) communications. Mm-waves communications are characterized by the high signal attenuation, which can only be overcome by highly directional antennas. The reduced interference compared to communication at lower frequencies, allows for a high degree of spatial reuse and potentially simpler Medium Access Control Protocols (MAC). But high directionality may cause deafness due to beam misalignments, and sudden communication blockages due to obstacles. We give an overview of mm-wave communication characteristics, and on the most important network and protocol design aspects, from beam-training and MAC to efficient network architectures.
