Determining precoding matrix indicators for visibility regions of a user equipment

Abstract

A user equipment (UE) includes one or more non-transitory computer-readable media that store one or more computer-executable instructions for selecting a precoding matrix indicator (PMI) for a visibility region (VR) of the UE. The UE includes at least one processor that is coupled to the one or more non-transitory computer-readable media, and configured to execute the one or more computer-executable instructions. The processor is configured to receive, from a base station (BS), an identification of the VR assigned to the UE. The BS includes an antenna array that has several antenna ports. The assigned VR includes a subset of the antenna ports of the BS. The processor is configured to determine a PMI for the assigned VR and transmit the PMI for the assigned VR to the BS.
