Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a mode in which the user equipment is enabled, wherein the mode is one of a non-standalone mode, a standalone mode, or a standalone mode and a non-standalone mode; determine whether to prioritize a first set of frequencies associated with a first radio access technology (RAT) or a second set of frequencies associated with a second RAT based at least in part on the mode in which the user equipment is enabled, wherein the first RAT is different from the second RAT; and perform a search of the first set of frequencies or the second set of frequencies based at least in part on whether the first set of frequencies or the second set of frequencies is prioritized. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine location information regarding the UE; and activate a receive beam of the UE in at least one symbol, associated with at least one transmit beam of at least one base station, based at least in part on the location information, wherein the UE is configured to activate the receive beam based at least in part on mapping information, at least partially determined by the UE, that indicates that the receive beam is associated with the location information. Numerous other aspects are provided.

Abstract: The apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a processing system. The processing system may manage an antenna beam. The processing system may be configured to monitor a parameter of a signal and widen the antenna beam of the apparatus for wireless communication when the parameter falls below a threshold.

Abstract: Methods and apparatus are provided for aggressive beam selection during a handover procedure. A User Equipment (UE) measures a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically. The UE reports measurements relating to one or more of the measured candidate downlink beams to a source BS. The UE receives a command to handover to the target BS, and in response to receiving the command, attempts to find a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the one or more candidate downlink beam.
