Hybrid Precoding in Cooperative Millimeter Wave Networks [PDF]

IEEE Transactions on Wireless Communications, 2021
In this paper, we study the performance of cooperative millimeter wave (mmWave) networks with hybrid precoding architectures. Considering joint transmissions and BS silence strategy, we propose hybrid precoding algorithms which minimize the sum power consumption of the base stations (BSs), for both fully- and partially-connected hybrid precoding (FHP ...
