Abstract:
A UE may be configured to communicate using one of analog beamforming or hybrid beamforming. The UE may receive a set of beamformed signals from a base station. The UE may determine a set of angular spread values associated with a set of clusters in a channel between the base station and the UE based on the set of beamformed signals received from the base station. The UE may transmit the set of angular spread values to the base station. The UE may receive, from the base station based on the set of angular spread values, a set of transmission ranks associated with at least one cluster of the set of clusters. The UE may communicate at least one data stream with the base station across the at least one cluster using the set of transmission ranks associated with the at least one cluster of the set of clusters.
