Design of Massive MIMO NOMA With Limited Feedback
In this letter, a low feedback nonorthogonal multiple access (NOMA) scheme using massive multiple input multiple output (MIMO) transmission is proposed. In particular, the proposed scheme can decompose a massive MIMO NOMA system into multiple separated single input single output (SISO) NOMA channels, and analytical results are developed to evaluate the performance of the proposed scheme for two scenarios, with perfect user ordering and with one bit feedback, respectively.
