Claim of US Patent No. 11,115,990


1. A method of wireless communication, comprising:receiving, by a user equipment (UE), an instruction to monitor at least one channel state information reference signal (CSI-RS);
identifying, by the UE, a current-serving reception beam based, at least in part, on the at least one CSI-RS;
receiving, by the UE, a first synchronization signal block (SSB) on the current-serving reception beam;
receiving, by the UE, one or more SSBs on one or more reception beams, wherein the one or more SSBs are received on different ones of the one or more reception beams;
determining, by the UE, that a quality of wireless communication performed using a second reception beam on which a second SSB was received is higher than a quality of wireless communication performed using the CSI-RS-identified current-serving reception beam on which the first SSB was received based on first and second metrics measured from the first and second SSBs, respectively, despite the instruction to monitor the at least one CSI-RS, wherein the second SSB is one of the one or more SSBs; and
switching, by the UE, from performing wireless communication using the current-serving reception beam to performing wireless communication using the second reception beam based on the SSB-based determination that the quality of wireless communication performed using the second reception beam is higher than the quality of wireless communication performed using the CSI-RS-identified current-serving reception beam.
