To satisfy the increasing demand of high data-rate services, provide better user experience, and alleviate the huge infrastructure investment of operators, device-to-device (D2D) communications have being considered as one of the key techniques in the 5G wireless networks. With D2D communications, proximity users in a cellular network can communicate directly to each other without going through the base station (BS). It can potentially increase spectral-efficiency (SE) and device energy-efficiency (EE) of communications. However, D2D communications may generate interference to the existing cellular network if not designed properly. Therefore, interference management is one of the most challenging and important issues in D2D communications. This talk will focus on interference management in D2D communications including quality-of-service (QoS) aware admission control and SE/EE based mode selection. Cross-layer optimization and concave-convex procedures (CCCP) are exploited to solve the related optimization problems.
Dr. Geoffrey Li is a Professor with the School of Electrical and Computer Engineering at Georgia Institute of Technology. He is also holding a Cheung Kong Scholar title at the University of Electronic Science and Technology of China since 2006. He was with AT&T Labs – Research for five years before joining Georgia Tech in 2000. His general research interests include statistical signal processing for wireless communications. Recently, he focuses on intelligent processing for communication networks. In these areas, he has published over 200 papers on referred journals in addition to over 40 granted patents and many conference papers, with over 30,000 citations. He has been listed as the World’s Most Influential Scientific Mind, also known as a Highly-Cited Researcher, by Thomson Reuters (almost every year). He has been an IEEE Fellow since 2006. He received the 2010 IEEE ComSoc Stephen O. Rice Prize Paper Award, the 2013 IEEE VTS James Evans Avant Garde Award, the 2014 IEEE VTS Jack Neubauer Memorial Award, the 2017 IEEE ComSoc Award for Advances in Communication, and the 2017 IEEE SPS Donald G. Fink Overview Paper Award. He also won 2015 Distinguished Faculty Achievement Award from the School of Electrical and Computer Engineering, Georgia Tech.
