 +Abstract: 5G—the next generation wireless cellular system—is under development in, e.g., the EU-project METIS, In this talk, we will discuss why a new system is needed and the key components that METIS believes will be part of 5G. One such key technology, device-to-device (D2D) communication,​ will be treated in more detail. D2D is particularly attractive for vehicle-to-vehicle (V2V) communication for traffic safety applications. However, such applications put stringent constraints on latency and reliability,​ which in turn make radio resource allocation a challenging research problem. We will pose the joint D2D and cellular user resource allocation as an optimization problem, which unfortunately is intractable as the number of users increases to practically interesting values. We therefore present a heuristic approach to solve the problem. Although the approach is still work in progress, initial results are promising, showing close to optimal performance for small systems and competitive performance for larger systems (for which the optimal performance is currently unknown). 
 +Bio: Erik G. Ström received the M.S. degree from KTH-Royal Institute of Technology, Stockholm, Sweden, in 1990, and the Ph.D. degree from the University of Florida, Gainesville,​ in 1994, both in electrical engineering. He accepted a postdoctoral position at the Department of Signals, Sensors, and Systems at KTH in 1995. In February 1996, he was appointed Assistant Professor at KTH, and in June 1996 he joined Chalmers University of Technology, Gothenburg, Sweden, where he is now a Professor in Communication Systems since June 2003.  Dr. Ström currently heads the Division for Communications Systems and leads the competence area Sensors and Communications at the traffic safety center SAFER, which is hosted by Chalmers. His research interests include signal processing and communication theory in general, and constellation labelings, channel estimation, synchronization,​ multiple access, medium access, multiuser detection, wireless positioning,​ and vehicular communications in particular. He was a co-guest editor for the Proceedings of the IEEE special issue on Vehicular Communications (2011) and the IEEE Journal on Selected Areas in Communications special issues on Signal Synchronization in Digital Transmission Systems (2001) and on Multiuser Detection for Advanced Communication Systems and Networks (2008). Dr. Ström was a member of the board of the IEEE VT/COM Swedish Chapter 2000--2006. He received the Chalmers Pedagogical Prize in 1998 and the Chalmers Ph.D. Supervisor of the Year award in 2009.
