A POMDP-Based Antenna Selection for Massive MIMO Communication
IEEE Transactions on Communications(2022)
摘要
We use a partially observable Markov decision process (POMDP) framework to design an optimal antenna selection policy for downlink transmit beamforming at a multi-antenna base station (BS) equipped with only a limited number of RF chains. Assuming that the channel state evolves according to a finite-state Markov process and that only the channel coefficients which correspond to previously selected...
