Two policies for wireless non‐orthogonal multiple access systems: System model and performance enhancement of far user

Summary Device‐to‐device (D2D)‐enabled non‐orthogonal multiple access (NOMA) network is introduced as promising candidate to support massive connectivity and satisfy the high‐throughput demand. In this paper, two schemes are investigated for situations associated with D2D users and interference from traditional cellular users. The base station equipped multiple antennas is designed to exploit higher diversity gain and make full use of spectrum...
