Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may communicate via a serving beam set of the UE, the serving beam set being one or more of a plurality of beams. The UE may measure another beam set in accordance with a measurement schedule configured to prioritize measurement on one or more adjacent beam sets associated with the serving beam set over one or more non-adjacent beam sets associated with the serving beam set. In some aspects, the one or more adjacent beam sets may be associated with one or more coverage areas that at least partially overlap a coverage area of the serving beam set, are adjacent to the coverage area of the serving beam set, or are associated with a measurement value that satisfies a threshold in the coverage area of the serving beam set. 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 measure one or more downlink reference signals using one or more candidate beams in a set of candidate beams to obtain reference signal received power (RSRP) measurements for the one or more candidate beams. The UE may estimate, for each of the one or more candidate beams in the set of candidate beams, a downlink spectral efficiency and an uplink spectral efficiency based at least in part on the RSRP measurements associated with the respective candidate beam. The UE may select a downlink receive beam and an uplink transmit beam based at least in part on the downlink spectral efficiency and the uplink spectral efficiency. Numerous other aspects are described.

Abstract: A base station may receive from a user equipment (UE) a proactive notification that the UE will perform a beam switch from a first UE beam to a second UE beam. In response, the base station may determine a beam switch slot on which the UE will perform the synchronized beam switch, and perform a link transient mitigation operation for communications with the UE after UE beam switch and until updating channel state information associated with a new UE beam. The base station may then receive from the UE channel state information feedback for a channel associated with the second UE beam, and adjust downlink data transmission parameters to be aligned with the second UE beam based on the received channel state information feedback (CSF). The base station may also adjust uplink data transmission parameters based on a sounding reference signal transmitted by the UE over the second UE beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, while camped on a first cell associated with a first radio access technology (RAT), a power management level for a communication using a second RAT, wherein the power management level indicates an available power for the communication using the second RAT, and wherein the available power is based at least in part on an exposure rate or an absorption rate. The UE may delay a transmission of a measurement report on the first cell based at least in part on the identification of the power management level. 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 allocate a first amount of power to one or more radios for a time window based on radio frequency (RF) exposure information and one or more other criteria. The UE may allocate a second amount of power to a selected channel or communication utilized by at least one radio of the one or more radios for one or more time frames within the time window based on the first amount of power allocated to the at least one radio for the time window. The UE may transmit the selected channel or communication based on the first amount of power or the second amount of power. Numerous other aspects are described.
