In this paper, we investigate antenna selection based on user velocity in frequency division duplex (FDD) massive MIMO system. In order to get this scheme, we first derive the system spectrum efficiency (SE) based on the estimated downlink channel and then analyze the relationship between the optimal number of antennas and the user velocity. Simulation results show that the proposed antenna selection scheme can improve SE.
