We consider a non-orthogonal multiple access aided ALOHA (NOMA-ALOHA) that can enhance the spectral efficiency by sending uplink packets of different power levels in wireless multiuser systems. In particular, we develop an asymmetric game theory model for NOMA-ALOHA that involves two different groups of users and analyze the mean rewards and payoffs of actions made by the users. While taking into account not only collisions, but also fading, the derived theoretical results are utilized to formulate a general-sum game with two groups of users and find mixed strategy Nash equilibrium (NE). Interestingly, the analytical and numerical results clearly show that, when the NOMA-ALOHA runs at an NE, a far-user can exploit an improved channel gain of a near-user in the other group in terms of the throughput.
