TITLE: Stable Throughput Regions of Opportunistic NOMA and Cooperative NOMA with Full-Duplex Relaying


SPEAKER: Dr. Vincent Wong

DATE:   Tuesday, 14 August 2018

ORGANIZER: IEEE Communications Society (Winnipeg Section)




Non-orthogonal multiple access (NOMA) is a spectrally efficient multiple access technique, which has the potential to meet the rapidly increasing traffic demand of the fifth generation (5G) wireless networks. With NOMA, multiple users can be simultaneously served by the same base station via exploiting the power domain in addition to the time and frequency domains. However, by sharing the frequency channel and transmit power among the paired NOMA users, NOMA may not always achieve better performance than orthogonal multiple access (OMA). In this talk, the basic idea of NOMA transmission is discussed. For downlink NOMA transmission with dynamic traffic arrival for spatially random users, two variants of NOMA schemes, namely opportunistic NOMA and cooperative NOMA with full-duplex relaying, are proposed to enhance the stable throughput region, which is characterized by using tools from queuing theory and stochastic geometry.  Results show that the sum rates of the proposed NOMA schemes over OMA are higher when users having more diverse target data rates are paired.



Vincent Wong is a Professor in the Department of Electrical and Computer Engineering at the University of British Columbia. His research areas include protocol design, optimization, and resource management of communication networks, with applications to the Internet, wireless networks, smart grid, mobile cloud computing, and Internet of Things. Dr. Wong is an Editor of IEEE Transactions on Communications and an Associate Editor of IEEE Transactions on Mobile Computing. He has served as a guest editor of IEEE Journal on Selected Areas in Communications and IEEE Wireless Communications. Dr. Wong is a Fellow of the IEEE.
