FULL-DUPLEX PROTOCOL DESIGN IN 5G NETWORKS

PROF. RISTO WICHMAN, AALTO UNIVERSITY, FINLAND

Risto Wichman received his M.Sc. and D.Sc. (Tech) degrees in digital signal processing from Tampere University of Technology, Tampere, Finland, in 1990 and 1995, respectively.  From 1995 to 2001, he worked at Nokia Research Center as a senior research engineer.  In 2002, he joined Department of Signal Processing and Acoustics, Aalto University School of Electrical Engineering, Finland, where he is a full professor since 2008.  His research interests include signal processing techniques for wireless communication systems, and full-duplex technology in particular.

Abstract

Research on in-band full-duplex for wireless communications and applications for cellular systems has been conducted for about a decade. The main problem hindering the adoption of full-duplex communications, the self-interference, has been tackled using different transceiver architectures. Several prototypes have been devised during the recent years showing that it is indeed possible to suppress the self-interference down to a noise level. This should make full-duplex a feasible add-on for cellular systems, but a break-through of full-duplex technology is still on the way. This talk explores the reasons behind the slow adoption of full-duplex in cellular systems and the necessary hooks required to include full-duplex capability in 5G specifications. Furthermore, most prominent use cases for full-duplex in cellular systems are discussed as well as some future directions for full-duplex research.
