报告摘要:To accommodate massive access for machine-type communication (MTC) in cellular networks, we propose a signal-to-interference ratio based clustering for the MTC. The cluster heads operate as single hop relays between successfully decoded MTC devices (MTCDs) and the base station (BS), reducing the signaling overhead. MTCDs randomly select channels to transmit on, and therefore create interference to each other. Unlike related work assuming known interference values for each link, we use stochastic geometry to characterize the received signal and interference powers. Given limited spectrum resources for MTC, we derive the outage probability expression and analytically calculate the maximum density of MTCDs that can be supported under an outage constraint. Moreover, the optimal partitioning of spectrum resources into the MTCD-to-cluster head links and relay links for maximum transmission capacity is presented.

 

演讲人简介Teng Joon (T. J.) Lim grew up in Singapore, obtained the B.Eng. degree in Electrical Engineering with first-class honours from the National University of Singapore in 1992, and the Ph.D. degree from the University of Cambridge in 1996. From September 1995 to November 2000, he was a researcher at the Centre for Wireless Communications in Singapore, one of the predecessors of the Institute for Infocomm Research (I2R). From December 2000 to May 2011, he was Assistant Professor, Associate Professor, then Professor at the University of Toronto’s Edward S. Rogers Sr. Department of Electrical and Computer Engineering. Since June 2011, he has been a Professor at the National University of Singapore’s Electrical & Computer Engineering Department, where he served as the Deputy Head (Research and Graduate Programs) from July 2014 to August 2015. He currently serves as Vice-Dean (Graduate Programmes) in the Faculty of Engineering.
