Abstract
In a particular implementation, a method of wireless communication includes searching, at a user equipment (UE) having a first subscriber identity module (SIM) and a second SIM, transmit beams from a base station and receive beams from the UE to determine a subset of transmit beams. The method also includes storing indicators of the subset of transmit beams in a database accessible to the UE in response to the second SIM performing a particular operation that causes the first SIM to perform a tune away operation. The method further includes, after completion of the particular operation, performing measurement operations on the subset of transmit beams to select a particular transmit beam of the subset of transmit beams and a corresponding particular receive beam for attachment to the base station.
