Title: New methods for Wireless LANs

Organizers: Dr Piotr Remlein, Poznan University of Technology, Poznan, Poland
Paper submission: via EDAS

The wireless local area networks (WLANs) are an example of great success. All over the world hundreds of millions WLAN devices are shipped every year. A great number of researches still develop new transmission and receiving methods to improve the WLAN performance. These methods (MIMO technique, Space Time Coding, transmit beamforming, LDPC encoding, MAC throughput enhancements, etc.) allow to achieve greater range and higher data rate of the wireless communications. The main goal of this special session is to discuss original technical problems ranged over the following topics connected with the next generation wireless LANs: Channel Coding, Space Time Coding, Multiple-Input Multiple-Output techniques, OFDM Systems, Multiuser Detection, Receiver Algorithms, Interference Rejection, MAC Efficiency Enhancements, Security Methods.

Title: PAPR reduction and power amplifier linearization for energy efficient 5G waveforms

Organizers: Prof. Daniel ROVIRAS, Dr Hmaied SHAIEK, CNAM, CEDRIC Laboratory;
Dr. Rafik ZAYANI, SUP’COM, INNOV’COM Laboratory, Ecole Supérieure des Commuications de Tunis
Paper submission: via EDAS

One of the key challenges of the 5G radio access technology is to design post-OFDM waveforms exhibiting: (i) low latency, (ii) high spectral efficiency and (iii) high robustness to asynchronism between users.
Being multi-carrier techniques, all these modulations exhibit a high PAPR making them sensible to High Power Amplifier nonlinearities. If the HPA is operated in its quasi linear region, the high PAPR of the multicarrier signal will not have any influence on the quality of the transmission. Nevertheless, this situation has a high cost in terms of energy efficiency, especially for mobile devices. Real HPA communication systems will then be operated as close as possible to the saturation region, in order to increase the power efficiency. By doing so, two distortion effects will appear: in out-of-band (broadening of the output signal spectrum) and in-Band (errors in the transmitted signal).
It is, so, important to limit and correct the nonlinearities effects by: (i) linearizing the HPA characteristics, (ii) reducing the PAPR of the transmitted multicarrier signal or (iii) compensating the nonlinearities at the receiver side.

Title: Techniques and Technologies for Smart Environments

Organizers: Prof. Luis M. Correia, IST / INESC-ID, Univ. Lisbon, Lisbon, Portugal
Paper submission: via EDAS

Smart Environments, like Body Area Networks, Smart Cities, Intelligent Buildings, and Intelligent Transportation Systems, are populated with many devices connected to wireless and mobile networks. Although this is not a new research area, there are still many issues to be dealt with, ranging for radio channel modelling to network approaches, which impact on the design of transmission techniques and communication protocols. Other application areas under study these days are also associated with Smart Environments, like Internet of Things and Machine Type Communications. The high density of connected nodes and their peculiarities in terms of traffic type, location, constrained resources, make Smart Environments a complex system of systems. This session intends to bring together papers exploring methods, models, techniques, strategies and tools, for Smart Environments, addressing specific aspects on the one hand, but enabling a global overview of the application to general perspective of these usage scenarios on the other hand.

Title: Trade-offs of green networking – from the access to the core

Organizers: Dr Filip Idzikowski, Poznan University of Technology (PUT), Poland
Paper submission: via EDAS

Green networking has become a well established topic in the networking community. Energy saving is searched for in different kinds of networks from the access up to the core (including intra- and inter data center networks, etc.). Energy saving however has its costs. The aim of this session is to provide an overview of the costs related to energy saving, and to compare the trade-offs across different sectors of the network and across different technologies (including wireless and wired networks). Suitable topics for this special session include but are not limited to:

  • Quality of Service (QoS)
  • Quality of Experience (QoE)
  • protection against network failures
  • devices lifetime

Title: 5G Ultra-Reliable Communication

Organizers: Dr Michał Sybis
Paper submission: via EDAS

Fifth generation (5G) of cellular networks is considered as a technology to provide connectivity for a wide range of devices and applications. It will not only increase the offered date rates, but also embrace new features. Ultra-Reliable Communication (URC) is one of the novel features, not present in today’s wireless systems, that is discussed in relation to the 5G networks. URC is often considered with low-latency transmission and is an essential feature for mission-critical applications, such as public safety, vehicular safety and industrial automation. This feature guarantees a communication service with a very high level of reliability (almost 100% of the time). The main objective of session is to present the papers that deal with solving the engineering problems posed by URC in 5G.
Suitable topics for this special session include but are not limited to:

  • M2M communication
  • V2V (5G/802.11p based) communication
  • Low latency Ultra Reliable Communication
  • Channel codes design for Ultra Reliable Communication
  • Different approaches to channel coding for Ultra Reliable Communication
  • Transmission methods for Ultra Reliable Communication

Paper submission: via EDAS

The increasing demand of mobile Internet and the Internet of Things poses challenging requirements for 5G wireless communications, such as high spectral efficiency, low latency and massive connectivity. Along with massive MIMO, millimeter wave communications, ultra dense network, non-orthogonal multiple access is one of the most promising techniques to cope with these demands, via non-orthogonal resources allocation. Non-orthogonal multiple access schemes allow multiple users to share time and frequency resources in the same spatial layer via power domain or code domain multiplexing. Examples include sparse code multiple access (SCMA), multi-user shared access (MUSA), multiple access with low-density spreading (LDS), NOMA with power-domain multiplexing, OTFS, variants of OFDM and others.

With the ongoing standardization intensive effort on waveform design for 5G, this special session is aimed at addressing key features of these schemes. High quality researchers from both academia and industry will discuss design principles, pros and cons. It is hoped that this provides a comprehensive comparison of diverse non-orthogonal access solutions from the perspective of spectral efficiency, system performance, receiver complexity, and so on, which researchers from academia and industry, as well as practioners, will find useful.
