Limited Feedback for 3D Massive MIMO under 3D-UMa and 3D-UMi Scenarios
For three-dimensional (3D) massive MIMO utilizing the uniform rectangular array (URA) in the base station (BS), we propose a limited feedback transmission scheme in which the channel state information (CSI) feedback operations for horizontal domain and vertical domain are separate. Compared to the t...
