Abstract:
Non-Orthogonal Multiple Access (NOMA) has recently been considered as a key enabling technique for 5G cellular systems. In NOMA, by exploiting the channel gain differences, multiple users are multiplexed into transmission power domain and then non-orthogonally scheduled for transmission on the same spectrum resources. Successive interference cancellation (SIC) is then applied at the receiver(s) to decode the message signals. In this talk, first I will briefly describe the differences in the working principles of uplink and downlink NOMA transmissions in a cellular wireless system. Then, for both uplink and downlink NOMA, I will discuss the problems of user clustering (i.e., grouping users into a single cluster or multiple clusters) and power allocations in NOMA cluster(s) under transmission power constraints, minimum rate requirements of the users, and SIC constraints. I will present a solution methodology for these problems and illustrate the comparative performance between NOMA and orthogonal multiple access (OMA) in various network scenarios. To this end, I will outline a framework to integrate downlink NOMA with coordinate multipoint (CoMP) transmission in a multi-cell scenario.
