- Abstract
- In this paper, we investigate stability region of hybrid uplink non-orthogonal multiple access (NOMA) in conjunction with non-cooperative game, where two users independently send packets with transmit power control according to fading channel gain to the same radio resource so that their packets are received at a base station (BS) with one of two target receive powers (TRPs). The BS then tries to decode the packets with successive interference cancellation (SIC) technique in power domain. We consider a symmetric non-cooperative game where the users (or players) send packets with one of two TRPs or no transmission. We examine the convexity of stability region at the mixed-strategy Nash equilibrium (NE) of the game, where no one's queue grows to infinity. Furthermore, we investigate how the stability region changes depending on the parameters of users' payoff.
