Joint Optimal Power Allocation and Beamforming for MIMO-NOMA in mmWave Communications
IEEE Wireless Communications Letters（2022）
摘要
In this letter, we propose an optimal joint power allocation and beamforming for MIMO-NOMA in mmWave communications. In this method, to reduce the system overhead, we consider a random near random far (RNRF) pairing scheme in our NOMA data transmission. We formulate an optimization problem to find the optimal power allocation and random beamforming (RBF) coefficients to improve the system performa...
