Prof. Ekram Hossain, FIEEE, will give a seminar with the title "Non-Orthogonal Multiple Access (NOMA) for 5G Wireless". Professor Ekram Hossain is affileated to the department of Electrical andComputer Engineering at University of Manitoba, Winnipeg, Canada.
The seminar is organized by the Division of Communication and Antenna Systems (CAS), Dept. of Electrical Engineering, Chalmers University of Technology. The Host of Prof. Ekram Hossain (University of Manitoba) is Dr. Mouhamed Abdulla. For more information regarding this seminar and research visit to Chalmers, please email:

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.
