T2: Spatial Modulation for MIMO Wireless Systems
Presented by: Marco Di Renzo (CNRS) Ali Ghrayeb (Concordia Univ.) Harald Haas (Univ. Edinburgh)
Time: 13:30–17:00
Room: TBA


The key challenge for future wireless communications is to make these networks energy-efficient and spectrum efficient at the same time. This results in a paradigm-shifting requirement which necessitates a clean-slate approach of wireless system design. Clearly, such approach will have to embrace the rich body of knowledge that has been created especially on Multiple-Input-Multiple-Output (MIMO) technology during the last 25 years. This motivates us to give a tutorial on an emerging wireless communications concept for 'massive' MIMO systems, which is today known under the name of Spatial Modulation (SM). SM has recently established itself as a beneficial transmission paradigm, potentially subsuming all members of the MIMO wireless system family, which exploits multiple antennas in a novel fashion. The research on SM has reached sufficient maturity to substantiate its claimed advantages compared with state-of-the-art standardized MIMO concepts, as well as its applications to other emerging wireless systems such as relay-aided, cooperative, small cell, optical wireless, and green communications. Furthermore, it has received sufficient attention to be implemented in testbeds, and holds the promise of stimulating further vigorous inter-disciplinary research in the next years. We believe that this is a timely topic and we anticipate that this tutorial will be of interest to many researchers/students/practitioners with different backgrounds.

Tutorial Objectives
Future wireless communication systems deployment, including fourth generation (4G) cellular systems, will be based on the MIMO transmission technology. Conventional MIMO schemes usually take advantage of the many antennas available at the transmitter by simultaneously transmitting multiple data streams from all of them. Furthermore, common open-loop MIMO schemes usually assume that all transmit-antennas are simultaneously active at any time instance. By properly choosing the transmission matrices, both multiplexing and transmit-diversity gains can be obtained via space-time coding. As a consequence, higher data rates and smaller error performance are obtained at the cost of: i) increasing the signal processing complexity at the receiver, which is caused by the need to counteract the interference created by simultaneously transmitting many data streams; and ii) making more stringent the synchronization requirements among the transmit-antennas.

Furthermore, more recently, with the advent of the green and sustainable information and communication era, state-of-the-art MIMO schemes are facing two additional major challenges: i) the need of multiple RF chains at the transmitter to be able to simultaneously transmit many data streams, which do not scale with Moore's law and make the transmitter very bulky; and ii) the need of independent power amplifiers for each RF chain, each one being responsible of the vast majority of the power consumed at the transmitter as well as being extremely power inefficient due to the stringent linearity requirements of state-of-the-art phase/amplitude modulations. For example, recent studies have shown that, for a fixed RF output power, the total power consumption of base stations linearly increases with the number of active RF chains.

These considerations imply that a major challenge of next-generation MIMO-enabled wireless networks is the design of multi-antenna transmission schemes with a limited number of active RF chains aiming at reducing circuitry complexity, inter-antenna synchronization requirements, inter-channel interference, signal processing complexity at the receiver, as well as at improving the energy efficiency. Fueled by these considerations, SM has recently established itself as an emerging and promising transmission concept belonging to the 'massive' MIMO wireless systems family but exploiting the multiple antennas in a novel way compared with state-of-the-art high-complexity and power-hungry classic MIMOs. This tutorial is intended to offer a comprehensive state-of-the-art survey on SM-MIMO, the critical appraisal of its beneficial application domains and their research challenges, the analysis of the related technological issues associated with the implementation of SM-MIMO, and, finally, the description of the world's first experimental activities in this research field.

T3: Cooperative Wireless Communications
Presented by: Lajos Hanzo, University of Southampton
Time: 09:00–12:30
Room: TBA


This overview introduces the principles of cooperative communication,
commencing with the introduction of the basic MIMO types of

1. Beamforming;

2. Space-time coding;

3. Spatial Division Myltiplexing;

4. Spatial Division Multiple Access;

The limitations of MIMOs relying on co-located array-elements are highlighted and it is shown, how the single-antenna-aided cooperative mobiles may circumvent these limitations by forming MIMOs having distributed elements. This concept is also referred to a Virtual Antenna Arrays (VAA). Then the corresponding amplify-forward and decode-forward protocols as well as their hybrids are studied. Channel coding has to be specifically designed for the VAAs in order to prevent avalanche-like error-propagation. Hence sophisticated three-stage-concatenated iterative channel coding schemes are proposed and it is argued that in the absence of accurate channel information at the relays the best way forward might be to use multiple-symbol differential detection. Indeed, it is rather unrealistic to expect that an altrustically relaying handset would also accurately estimate the source-relay channel for the sake of high-integrity coherent detection. EXIT-chart-aided designs are used for creating near-capacity solutions and a range of future research directions as well as open problems are stated.

Tutorial Objectives
Upon completion of this tutorial, participants will be able to:

o Decide upon the AF versus DF design benefits;

o Resolve the coherent versus non-coherent cooperation dilemma;

o Engage in research on novel cooperative solutions for wireless systems;

Tutorial Outline

    Cooperative Adaptive Modulation;
    Successive Relaying Aided Near-Capacity Irregular Distributed Space-Time Coding;
    Coherent versus Non-Coherent Detection;
    Resource-Optimized Differentially Modulated Hybrid AF/DF Cooperation Dispensing with Channel Estimation;
    Distributed Channel Coding;
    Multiple Source Cooperation;
    Synchronous versus Asynchronous Cooperative Systems;

Primary Audience
Whilst this overview is ambitious in terms of providing a research-oriented outlook, potential attendees require only a modest background in wireless networking and communications. The mathematical contents are kept to a minimum and a conceptual approach if adopted. Postgraduate students, researchers and signal processing practitioners as well as managers looking for cross-pollination of their experience with other topics may find the coverage of the presentation beneficial. The participants will receive the set of slides as supporting material and they may find the detailed mathematical analysis in the books coauthored by the presenter.

This tutorial creates a bridge between classic MIMOs having co-located elements and distributed MIMOs. Furthermore, intrinsically amalgamates the channel coding and transmission schemes and reviews the pros and cons of coherent versus non-coherent cooperative transceivers;

T5: Smart Direct-LTE Communication: An Energy Saving Perspective
Presented by: Shahid Mumtaz, Institute of Telecommunication
Time: 09:00–12:30
Room: TBA


Device to Device (D2D) communication underlying a cellular infrastructure is discussed in this paper. When enabling D2D communication in the system, one can see several benefits compared to the conventional infrastructure based communication, such as improved energy efficiency, increase overall system throughput and decrease traffic load in the network. The aim of this tutorial is to give an energy efficient perspective of D2D communication and help the researcher, operators and manufactures to see the benefits when facilitating D2D communication in the network. This tutorial explains the fundamental concepts about D2D communication to technical perspective, business opportunity and open issues when deploying D2D communication. We use 3GPP Long Term Evolution Advanced (LTE-A) as a baseline while explaining D2D communication.

Tutorial Objectives
Energy efficiency has emerged as one of the most important research topics for radio systems. This leads us to develop an energy efficient mechanism which adjusts transmission power according to the traffic load and reduces the energy per bit usage. The vision of Europe 2020 is to become a smart, sustainable and inclusive economy, and as part of these priorities the EU have setforth the 20:20:20 targets where greenhouse gas emissions and energy reduction of primary use should be reduced by 20% while 20% of energy consumption should come from renewable resource. In fact, in today's energy conscious society, Information and Communication Technology (ICT) accounts for 2% of the global CO2 emissions. A medium sized cellular network uses as much energy as 170,000 homes. While the cost of powering the existing BSs accounts for a staggering 50% of a service provider's overall expenses. Therefore new solutions are required whereby operators can accommodate additional traffic volume whilst reducing their investment in new infrastructure and beyond that significantly reduces their energy bill. Moreover, the EU political agenda in unison with expected growth in mobile data has identified cost and energy per bit reduction as a stringent design requirement for mobile networks of the future.

In order to solve the energy consumption issues mentioned above, to enhance the communication capacities and capabilities and to introduce new services, research is performed on many subjects, e.g. antenna design, data compression, modulation techniques among others. A very recent and less tackled topic is device to device (D2D)communication underlying cellular networks.

Therefore, the objective of this tutorial is to give an energy efficiency perspective of D2D communication to assist all major mobile stakeholders to perceive the benefit when facilitating D2D communication in the network. This tutorial initially elaborates on
the fundamental concept surrounding D2D communication towards a technical perspective, business opportunities and open challenges. The presentation will describe the details of the players and the opportunity as well as real-world insights into the challenges associated with network operations and management and the radio air interface interference problems. System level simulation is used to analyse the energy efficiency of D2D network.

Tutorial Outline

      D2D will be overviewed and different short range technologies will be discussed.
      This section describes the motivation for operators to deploy D2D and for customers to use the D2D mode.
    D2D Challenges

      o Energy efficient D2D Duplexing Mode
      o Energy efficient D2D Resource Management
      o Energy efficient D2D Interference Management
      o Energy efficient D2D Link Adaptation/HARQ
      o Energy efficient D2D Channel Measurement
      o Energy efficient D2D Signalling, Power control and Mobility Management
    D2D Application & Business opportunities
      This section describes the different D2D applications (i.e. augmented reality, BUMP), business models and opportunities for mobile stockholders.
    Energy efficient System Level simulation Analysis
      This section explains how to integrate D2D network in system level simulator (SLS) and different building blocks of SLS. Simulation results will be presented to show the energy efficiency of D2D network.
    Future of D2D
      This section explains the open issues that need to be solved if D2D is really to become a successful business paradigm.

Primary Audience
Graduate students, post-docs, and any research engineers in the areas of electronic engineering, information and communication engineering, computer science and engineering, and telecommunication networks. Young faculties in the above-mentioned fields should also be benefited from the course.

D2D communication is a relatively new research area, which has not been addressed in a systematic way in the past major IEEE Conferences as a tutorial. We believe that this is the first kind of tutorial on D2D communication that will be presented in any VTC conference . The two major novelties of this course are: 1) Give detail introduction of D2D communication, Protocol stack and it core Architecture in LTEA network; 2) A comprehensive LTE-A System Level Simulator tool for analysis of the interference issue and the corresponding network energy efficiency containing hundreds of D2D and macro users.

T8: V2V Safety Communications: An overview and examination of technical challenges
Presented by: John B. Kenney, Toyota InfoTechnology Center, USA; Gaurav Bansal, Toyota InfoTechnology Center, USA
Time: 13:30–17:00
Room: Seminar 4


In this tutorial we cover the most important aspects of Dedicated Short Range Communications (DSRC), also known as Cooperative ITS. This technology is currently being considered for deployment in North America, Europe, and other parts of the world. DSRC is used to communicate vehicle-to-vehicle (V2V) and vehicle-to/from-infrastructure (V2I), enabling a set of compelling applications for safety, mobility, commerce, and environmental improvement. This tutorial focuses on the safety use case. The tutorial material includes the various layers of the protocol stack, V2V & V2I collision avoidance applications, and the technical challenges that are being addressed on the path to deployment. We will talk about government-sponsored field tests, like the US DOT Safety Pilot and the European DRIVE C2X, which are moving the technology out of the lab and into realistic vehicular environments. After presenting the basics of DSRC, we focus on one specific research problem that is currently of great interest: DSRC Channel Congestion. We discuss the merits of various approaches to address congestion, including avoidance and active control, as well as targets for control (message rate, transmit power, bit rate, and advanced techniques like carrier sense control). Finally, as a case study we will discuss our specific research on adaptive message rate control. The primary goal of the tutorial is to empower the attendee to participate in this important emerging technology, whether as a researcher, a developer, or a planner.

Tutorial Objectives
Upon completion of this tutorial, attendees will be able to:
1.Master the fundamentals of a critical emerging VTC technology, DSRC
2.Design collision avoidance applications based on V2V communication
3.Evaluate the impact of strategic investment on DSRC deployment
4.Join the DSRC research community, contributing to solutions for congestion control and other technical challenges

Tutorial Outline

      1.DSRC Technology
      2.Vehicular Safety Communications
      3.Overview of the Protocol Stack
      4.Technical Challenges on the Path to Deployment
      5.Policy Challenges on the Path to Deployment
      6.Government Sponsored Field Tests
      7.DSRC channel congestion control

Primary Audience
The intended audience includes researchers in academia, engineers working in industry (car companies, equipment suppliers, chip manufacturers, etc.), governmental organizations responsible for deployment and regulatory decisions (road authorities, governmental labs), and also other international attendees. The tutorial is structured to provide value to attendees who come with only a basic knowledge of data networking, but also to deliver technical insight to those with more advanced backgrounds.

Vehicular safety communication is an important emerging field. This tutorial is well-timed to provide the attendee with critical technical and policy knowledge. After nearly ten years of active research, the field is reaching a level of maturity. However, significant challenges remain as the US Government considers a deployment mandate.
