On Optimizing Feedback-Rate Allocation for Downlink MIMO-NOMA With Quantized CSIT
IEEE Open Journal of the Communications Society, 2020 We consider multiple-input multiple output (MIMO) non-orthogonal multiple access (NOMA) downlink channels with zeroforcing beamforming transmission. The base station has multiple transmit antennas while all mobile devices have single receive antenna ...
