Abstract
Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The UE may measure the reference signal received power (RSRP) of each of a plurality of downlink beams during a beam sweep and modify an automatic gain control (AGC) state of the UE based on the difference in RSRP between a current downlink beam and an expected downlink beam expected to be selected by the base station for subsequent unicast downlink transmissions to the UE. In some examples, the expected downlink beam may have a highest RSRP among all of the measured RSRPs of the different downlink beams Other aspects, features, and embodiments are also claimed and described.
