Abstract: Wireless communications systems and methods related to user equipment (UE) idle mode mobility in a wireless communication network are provided. A wireless communication device establishes a network session with a wireless communication network. The wireless communication device reselects a first cell for camping, wherein the first cell is associated with the wireless communication network. The wireless communication device monitors for first system information from the first cell. The wireless communication device reselects a second cell for camping in response to a failure to receive the first system information. The second cell is associated with the wireless communication network and different from the first cell. The wireless communication device maintains the network session during the reselecting the first cell for camping and the reselecting the second cell for camping.

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: 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.
