AoD-Adaptive Channel Feedback for FDD Massive MIMO Systems With Multiple-Antenna Users
In this paper, we propose an efficient feedback scheme for an angle of departure (AoD) based channel estimation in frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) systems with multiple antennas at the users. The channel feedback scheme is based on zero-forcing block dia...
