T3: Near-Capacity Wireless Multimedia Design and Streaming for 5G
Presented by: Lajos Hanzo, Chair of Telecommunications School of ECS, Univ. of Southampton
Time: Half-day AM (start time TBA)
Room: TBA
Abstract—In the multimedia era we live in much of the tele-traffic is generated by smart phones and tablet computers exchanging high-quality, high-rate video signals, which is responsible for the data-Tsunami we experience. This trend is set to continue during the ensuing 5G era and hence the high-compression yet error-resilient streaming of multimedia signals is of prime importance. Fortunately, most multimedia source signals are capable of tolerating lossy, rather than lossless delivery to the human eye, ear and other human sensors. The corresponding lossy and preferably low-delay multimedia source codecs however exhibit unequal error sensitivity, which is not the case for Shannon’s ideal entropy codec. In this research-review a unified treatment of near capacity multimedia communication systems is offered, where we focus our attention not only on source and channel coding aspects but also on their iterative decoding and transmission problems. There is a paucity of up-to-date surveys and tutorials on this important subject, hence this course aims to fill the related gap. A critical appraisal of source-compression, channel coding transmission and their joint holistic treatment is offered.
Tutorial Objectives
o To reviews the classic Shannonian lessons on multimedia communications - is the source- and channel-coding separation theorem still valid for the high-compression multimedia codecs of the 21st century?
o To cover audio/video compression basics, video standards and multi-layer coding;
o To familiarize the participants with iterative detection and Extrinsic Information Transfer (EXIT) charts;
o To review radically new near-capacity variable-length codes designed for multimedia communications;
o To quantify, how closely can we approach capacity and what is the price of approaching it?
o To review audio/video streaming and Multi-Functional Antenna Arrays (MFAA);
o To discover the benefits of short block codes, unity-rate codes and three-stage concatenated transceivers;
o To demonstrate the benefits massive MIMO systems, which are capable of completely dispensing with FEC codecs;
o To review promising 5G candidates and components;

T5: Information Centric Networks: Issues and Opportunities in Vehicular Networks by Cedric Westphal (Huawei/UCSC) and Giovanni Pau (UCLA/UPMC) has been cancelled
T6: Emerging Concepts and Technologies towards 5G+ Wireless Networks
Presented by: Halim Yanikomeroglu (Carelton University)
Time: Half-day PM (start time TBA)
Room: TBA
Abstract—enabling a further traffic increase of around 1,000 times, latency reduction of around 100 times, device increase of around 100 times in the next 15 years or so, while no customer is willing to pay more for the wireless pipe itself: the so called “traffic-revenue decoupling”. Moreover, many experts warn that the low-hanging fruits in wireless research (especially in information theory, communications theory, and signal processing) have already been collected. While the research community is full of ideas (as usual), many of these ideas are either not-too-relevant (i.e., not in the bottleneck areas) or they are in areas in which progress toward a tangible implementation is too slow.
The overall goal of the tutorial is to identify
• the emerging concepts and technologies, and
• the necessary analytical tools to study them (such as optimization, game theory, dynamic feedback control, and artificial intelligence).
Towards that end, a number of important components will be presented in the single coherent framework of 5G cellular networks with a “systems” scope and approach.

T8: Multi-way Full Duplex Communication and Cooperation
Presented by: Prof. Dr. Aydin Sezgin (Ruhr University Bochum) and Dr. Anas Chaaban (KAUST)
Time: Half-day (start time TBA)
Room: TBA
Abstract—Higher data rates, improved link quality, and low latency are demanded features of a variety of applications in wireless communications nowadays. These demands are however confronted by limitations in the available wireless spectrum and energy storage devices, which poses challenges to researchers and engineers worldwide. Multi-way communication and cooperation (appearing naturally, for instance, body area networks) are two resource-efficient techniques which are potential solutions for the aforementioned challenges in future communication systems (such as 5G and IoT). These techniques benefit from the presence of intermediate nodes acting as relays, which in turn enables the use of modern communication strategies to establish cooperation between several nodes, such as network coding. As a consequence there is an increasing need for the understanding of the fundamental characteristics of multi-way networks and of cooperation. This tutorial sheds light on this topic by reviewing state-of-the-art results on two-way and multi-way relay channels, and discussing opportunities and challenges therein. In addition, some live-demos are shown from the wireless full-duplex testbed illustrating the practical feasibility of full-duplex multi-way communication.
Tutorial Objectives
Higher data rates, improved link quality, and low latency are demanded features of a variety of
applications in wireless communications nowadays. These demands are however confronted by limitations
in the available wireless spectrum and energy storage devices, which poses challenges to researchers and
engineers worldwide. The tutorial presents two resource-efficient techniques, multi-way communication
and cooperation, which are potential solutions for the aforementioned challenges.
This tutorial will focus mainly on the two-way relay channel (TWRC) and generalizations thereof, and will span
both theoretical foundations and practical issues that have been developed in the recent years. It starts
with a brief overview of the two-way channel as a starting point. Then, it continues with the TWRC,
outlining various transmission schemes and their performance comparisons.
Next, performance benefits of two-way relaying in a wireless system with multiple antenna nodes will
be addressed. In this case, the multiplexing gain arising from the additional flexibility of pre-/post-coding
design, combined with physical layer network coding can lead to vast performance improvements. We
then investigate how this performance improvement is affected when multiple nodes wish to exchange
information in the so-called multi-way relay channel. Finally, we comment on the practical fea-
sibility of two-way communications, the issue of half-duplex versus full-duplex in-band relaying. Here,
we will show a demo on how full-duplex communication is performed on softwared defined
radios using USRP devices from Ettus, illustrating the practical feasibility of full-duplex communication.
We also will discuss the deployment of two-way relaying within existing wireless standards. We conclude
with a discussion of opportunities, challenges, and future research.
The tutorial has copious illustrations with a minimum mathematical content. The aim is to build intuition
and insight into the important topics of multi-way communication and cooperation while leaving the
technical details to references. The tutorial is based on the experience of the instructors accumulated
over several years of cooperation with both academia and industry. This experience combined with solid
theoretical background will help participants to better understand important theoretical concepts and their
application and impact on the practical wireless system design.
