Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a mapping of more than one antenna element, associated with an antenna module or panel that is integrated with a radio frequency integrated circuit (RFIC), to an RFIC port via one or more switches. The UE may select antenna elements from the more than one antenna element based at least in part on one or more conditions being satisfied. The UE may perform, via the antenna elements, a communication to a network node. Numerous other aspects are described.

Abstract: Method and apparatus for a beam panic design. The apparatus measures at least one subset of beams of a set of beams received from a network entity. The apparatus monitors for a change within a subset of the measured beams having a highest signal quality. The apparatus measures a rate of the change of the subset of the measured beams having the highest signal quality, in response to detection of an occurrence of the change of the subset of the measured beams having the highest signal quality. The apparatus initiates a beam panic mode based on at least the rate of change of the subset of the measured beams having the highest signal quality is less than a first threshold

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for operating a wireless device pursuant to radio frequency (RF) exposure compliance. A method that may be performed by a wireless device includes determining a transmit power associated with a transmission occasion and determining an energy usage associated with the transmission occasion based on the transmit power. The method also includes determining a total energy usage for a time window or a time interval associated with a RF exposure limit based on the energy usage associated with the transmission occasion. The method further includes transmitting a signal in the transmission occasion at the transmit power if the total energy usage satisfies an energy budget.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first reference signal (RS). The UE may identify a set of UE beams based at least in part on signal strengths of the first RS as measured via at least one UE beam of the set of UE beams. The UE may transmit, based at least in part on the first RS, a report including an indication of a network node beam for communication with the UE, the indication based at least in part on a signal strength of the first RS using a first UE beam of the set of UE beams. The UE may receive a second RS using the set of UE beams. The UE may identify, based at least in part on the second RS, a second UE beam of the set of UE beams, identification based at least in part on a spectral efficiency associated with the second UE beam. The UE may communicate with the network node using the second UE beam. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a slot or a symbol where a channel state information reference signal (CSI-RS) for a Procedure 2 (P2) resource is to be scheduled. The UE may schedule a candidate UE beam or a serving UE beam for the slot or the symbol. The UE may measure a spectral efficiency associated with the P2 resource. The UE may prepare a report that indicates one or more characteristics of the candidate UE beam or the serving UE beam. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a single rank reference signal. The UE may obtain, for multiple candidate beams, one or more single rank measurements from the single rank reference signal. The UE may identify, for each respective candidate beam included among the multiple candidate beams and based at least in part on the one or more single rank measurements obtained from the single rank reference signal for the respective candidate beam, a multiple rank spectral efficiency metric. The UE may identify, from among the multiple candidate beams and based at least in part on the multiple rank spectral efficiency metric associated with each respective candidate beam, a beam to use to communicate with the network node. Numerous other aspects are described.

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.
