Transmit antenna selection based on sum rate and fairness for downlink NOMA


In this paper, a transmit antenna selection (TAS) scheme is proposed for two-user downlink non-orthogonal multiple access (NOMA) network, which improves sum rate by considering the fairness between users. The proposed TAS-NOMA scheme is composed of two stages: In the first stage, base station choses k transmit antennas among its Nt antennas corresponding to… (More)
