Title: WIRELESS COMMUNICATION SYSTEM THAT PERFORMS BEAM REPORTING BASED ON A COMBINATION OF REFERENCE SIGNAL RECEIVE POWER AND CHANNEL STATE INFORMATION METRICS
Abstract:
A base station receives a report of channel state information (CSI) computation capability from a UE, configures the UE with X and Y values based on the reported computation capability, performs a beam sweep by transmitting direction-unique beams, and receives a beam measurement report from the UE comprising a reference signal receive power (RSRP) of Y strongest beams of the transmitted beams and at least a portion of the CSI of X strongest beams of the Y beams. Based on the beam measurement report, one of the X beams is selected to configure the UE for subsequent data and control channel transmissions. X and Y are positive integers, Y is greater than or equal to X, and Y is at least 1.
