Claim 3:
4. A method for beam management by a user equipment (UE) in a wireless communication system, the method comprising:
identifying a plurality of resources corresponding to different transmit (Tx) beams configured for measurement by the UE;
measuring a layer one reference signal received power (L1-RSRP) for the plurality of resources;
determining a selected Tx beam of the different Tx beams based on measured L1-RSRP for the plurality of resources, wherein an L1-RSRP value corresponding to the selected Tx beam is measured with a predetermined L1-RSRP accuracy to provide that the selected Tx beam is within a number of largest L1-RSRP values of the measured L1-RSRP of the different Tx beams; and
generating a report including an indication of the selected Tx beam and the L1-RSRP value measured with the predetermined L1-RSRP accuracy,
wherein the plurality of resources is configured as channel state information reference signal (CSI-RS) resources corresponding to the different Tx beams, and wherein the predetermined L1-RSRP accuracy for the CSI-RS transmitted with a density of 3 and a bandwidth of 48 physical resource blocks (PRBs) is ±4.5 dB when the corresponding SNR is at least −3 dB.
