Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a signal, transmitted by a base station, using a set of candidate beams. The UE may communicate, with the base station based at least in part on the measurement of the signal, using a first beam from the set of candidate beams. The UE may determine to switch the first beam based on a first value for a beam parameter associated with a second beam, from the set of candidate beams, satisfying a condition. The UE may measure, based at least in part on the determination to switch the first beam, the second beam to obtain a second value of the beam parameter. The UE may switch the first beam to the second beam if the second value satisfies a condition. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a method for wireless communication at a user equipment (UE). The method includes selecting, for each of a plurality of periodic search opportunities, one receive beam of a plurality of receive beams for receiving at least one synchronization signal. The plurality of periodic search opportunities includes a plurality of regular search opportunities and a plurality of prioritized search opportunities. The plurality of receive beams includes at least one prioritized receive beam and at least one additional receive beam. The selecting includes selecting from the at least one prioritized receive beam for each of the plurality of prioritized search opportunities; and selecting from the plurality of receive beams for each of the plurality of regular search opportunities. The method further includes receiving, at each of the plurality of periodic search opportunities, the corresponding at least one synchronization signal using the corresponding selected receive beam.

Abstract: Aspects described herein relate to receiving, from a base station, a transmit beam including a synchronization signal block (SSB) of multiple broadcast signals transmitted over multiple symbols, wherein receiving the transmit beam includes switching among multiple receive beams for each of the multiple symbols to receive a corresponding broadcast signal of the multiple broadcast signals, measuring a signal metric of each of the multiple broadcast signals as received via a corresponding receive beam of the multiple receive beams in a corresponding symbol of the multiple symbols, and selecting, based on the signal metric measured for each of the multiple broadcast signals, a receive beam of the multiple receive beams for communicating with the base station.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication. In some aspects, the scheduled entity detects a fluctuation in a beam strength of at least one transmit beam from a scheduling entity. The scheduled entity transmits a first message to the scheduling entity, the first message indicating at least the fluctuation in the beam strength of the at least one transmit beam from the scheduling entity.

Abstract: The choice of a transmit (Tx)-Receive (Rx) beam pair out of many available beam pairs between a base station and a millimeter wave (mmW)-capable UE is directly related to the performance of transmission between the base station and the UE. A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) capable of (mmW) communication are disclosed to determine a new serving Tx-Rx beam pair based on priorities of the plurality of Tx-Rx beam pairs. The UE may select a Transmit (Tx)-Receive (Rx) beam pair from a plurality of Tx-Rx beam pairs available at the UE for measurement, based in part on a priority of the Tx-Rx beam pair, and update the priority of the selected Tx-Rx beam pair based in part on a combination of static information and dynamic information of the selected Tx-Rx beam pair.
