Rate and Energy Efficiency Improvements of Massive MIMO-Based Stochastic Cellular Networks With NOMA
Publikováno v:
IEEE Transactions on Green Communications and Networking. 5:1467-1481
Non-orthogonal multiple access (NOMA) coupled with massive multiple-input multiple-output (MIMO) base stations hold immense potential in increasing the spectral and energy efficiencies while enabling massive access of future cellular networks. To thi
