Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a serving cell, a control signal indicating a set of parameters for a target cell available for handover for the UE and indicating the target cell is configured to transmit an aperiodic reference signal during a handover procedure. The UE may receive a command that identifies the target cell for a handover from the serving cell, and the command may indicate one or more resources associated with the aperiodic reference signal. The UE may receive, from the target cell, the aperiodic reference signal over the one or more resources. The UE may transmit a random access message based on time information or frequency information obtained from the aperiodic reference signal.

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.
