Title: Device-to-device (D2D) communications in a cellular network

Speaker: Ricardo Blasco, Ericsson Research

Abstract: A first set of features for LTE systems enabling device-to-device (D2D) communication in cellular systems have been standardized by 3GPP in Release 12 (frozen in March 2015). D2D communications depart from the fully centralized model  that has been applied to cellular systems from their early days, and present new opportunities for operators as well as challenges to the existing cellular systems. In this talk, we will look at the differences between traditional, centralized, cellular communication and D2D communication, discuss the technical challenges and solutions, and present some of the standardized features for 4G/LTE. We will conclude the talk with a look at the future of D2D, including a brief discussion of ongoing work in 3GPP (Releases 13 and 14).

Biography: Ricardo Blasco Serrano was born in Barcelona (Spain) in 1983. He received his M.Sc. degree in Telecommunication Engineering from the Technical University of Catalonia (UPC, Spain) in 2007. In 2006 he got a scholarship from the Signal Theory and Communications department at UPC to support Turbo Coding activities. During 2006-2007 he was at Lund University(LU, Sweden) as an exchange student. There he wrote his Master Thesis ("Joint Selection of Channel and Voice Coding for Secure Voice") in cooperation with Business Security AB.

Shortly after receiving his M.Sc. degree he joined the Communication Theory laboratory at the KTH School of Electrical Engineering. He obtained the PhD degree in Electrical Engineering in 2013 (advisers Prof. Mikael Skoglund and Assoc. Prof. Ragnar Thobaben), after which he joined Ericsson Research. His research interests are on communication and coding strategies for cooperation and coordination in networks.
