Radio resource management is of central importance in emerging heterogeneous networks. As the size of cells continues to shrink, traffic variations over time in a given cell become increasingly pronounced. Adapting resource allocation across cells to their traffic conditions is both rewarding and challenging. In this talk, we describe a framework for modeling the topology of a multi-cell system, the dynamic traffic, user association, and radio resource allocation in a relatively slow timescale. We formulate convex and nonconvex optimization problems that can be solved efficiently to minimize the average packet sojourn time in a network of up to 100 cells. Simulation shows significant throughput and delay advantages over optimized static allocation schemes.

He was a R&D Engineer in the Center for Wireless Communications (now the Institute for Infocom Research), Singapore, from 1998 to 1999. He has held visiting positions at the Norwegian University of Science and Technology in summer 2006, the Chinese University of Hong Kong in 2010-2011, and Massachusetts Institute of Technology in 2014-2015. He has been an Associate Editor of IEEE Transactions on Information Theory, an Editor of Foundations and Trends in Communications and Information Theory, and a Guest Editor for the IEEE Journal on Selected Areas in Communications. He received the Huber and Suhner Best Student Paper Award in the International Zurich Seminar on Broadband Communications in 2000 and is a co-recipient of the IEEE Marconi Prize Paper Award in Wireless Communications in 2010. He is also a recipient of the NSF CAREER Award in 2007. His research interests are in information theory, communications, networking, and signal processing.
