Scientific Challenges of 5G
by Mérouane Debbah, Vice-President, Huawei France R&D, France

Abstract: The evolution of cellular networks is driven by the dream of ubiquitous wireless connectivity: Any data service is instantly accessible everywhere. With each generation of cellular networks, we have moved closer to this wireless dream; first by delivering wireless access to voice communications, then by providing wireless data services, and recently by delivering a WiFi-like experience with wide-area coverage and user mobility management. The support for high data rates has been the main objective in recent years, as seen from the academic focus on sum-rate optimization and the efforts from standardization bodies to meet the peak rate requirements specified in IMT-Advanced. In contrast, a variety of metrics/objectives are put forward in the technological preparations for 5G networks: higher peak rates, improved coverage with uniform user experience, higher reliability and lower latency, better energy efficiency, lower-cost user devices and services, better scalability with number of devices, etc. These multiple objectives are coupled, often in a conflicting manner such that improvements in one objective lead to degradation in the other objectives. Hence, the design of future networks calls for new optimization tools that properly handle the existence and tradeoffs between multiple objectives.

Opportunistically Cooperating Radios in Action
by Andreas Polydoros, University of Athens, Greece

Abstract: The intriguing notions of opportunism and cooperation have been researched extensively within the wireless communication systems and networks academic community. They represent samples of advanced techniques explored in order to address the surging demand for broadband mobile capacity, the requirement for ubiquitous coverage and the need for available spectrum.
The field being enormous in scope, we narrow the presentation by first providing a clarification/definition of the concepts involved and the associated performance metrics whose improvement is sought. We identify some of the reasons why certain heightened expectations may actually not be attainable, hence explain the rather limited deployment of these ideas in current practice. We also identify a scenario (MANET) where indeed they make a major difference in action. Results from ongoing research in the latter field will be presented which show how critical it is to model and analyze true (as opposed to idealized) transceiver processing within a stochastic-geometry context.


Mérouane Debbah entered the Ecole Normale Supérieure de Cachan (France) in 1996 where he received his M.Sc and Ph.D. degrees respectively. He worked for Motorola Labs (Saclay, France) from 1999-2002 and the Vienna Research Center for Telecommunications (Vienna, Austria) until 2003. From 2003 to 2007, he joined the Mobile Communications department of the Institut Eurecom (Sophia Antipolis, France) as an Assistant Professor. Since 2007, he is a Full Professor at Supelec (Gif-sur-Yvette, France). From 2007 to 2014, he was director of the Alcatel-Lucent Chair on Flexible Radio. Since 2014, he is Vice-President of the Huawei France R&D center and director of the Mathematical and Algorithmic Sciences Lab. His research interests are in information theory, signal processing and wireless communications. He is an Associate Editor in Chief of the journal Random Matrix: Theory and Applications and was an associate and senior area editor for IEEE Transactions on Signal Processing respectively in 2011-2013 and 2013-2014. Mérouane Debbah is a recipient of the ERC grant MORE (Advanced Mathematical Tools for Complex Network Engineering). He is a IEEE Fellow, a WWRF Fellow and a member of the academic senate of Paris-Saclay. He is the recipient of the Mario Boella award in 2005, the 2007 IEEE GLOBECOM best paper award, the Wi-Opt 2009 best paper award, the 2010 Newcom++ best paper award, the WUN CogCom Best Paper 2012 and 2013 Award, the 2014 WCNC best paper award as well as the Valuetools 2007, Valuetools 2008, CrownCom2009 , Valuetools 2012 and SAM 2014 best student paper awards. In 2011, he received the IEEE Glavieux Prize Award and in 2012, the Qualcomm Innovation Prize Award.

Andreas Polydoros was educated in Athens, Greece (Diploma, EE), SUNY Buffalo (Master’s, EE) and the University of Southern California (Ph.D., EE), in 1977, 1979 and 1982, respectively. He served on the faculty of USC, a Professor since 1992, and a few years later returned to Greece as Professor in the Physics Department of the University of Athens. He was elected IEEE Fellow (1995) for contributing to spread-spectrum systems. He originated the concept and was co-granted the first US patent on Per-Survivor Processing (PSP) in the early ‘90’s. He subsequently co-founded, in 2000, TrellisWare Technologies of San Diego, CA. Upon returning to Europe, he shifted interest to advanced concepts such as flexible radio systems and networks. He was recently included in the Highly Cited Researchers list of the Web of Science.
