Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a beam management window based at least in part on one or more downlink traffic parameters satisfying a window opening condition. The UE may perform a beam sweep on a set of beams associated with one or more physical downlink shared channel (PDSCH) demodulation reference signal (DMRS) transmissions that are received during the beam management window. The UE may select, among the set of beams associated with the one or more PDSCH DMRS transmissions received during the beam management window, a beam to use to communicate with a network node based at least in part on one or more metrics associated with each respective beam included in the set of beams. 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 that one or more thresholds are satisfied. The UE may estimate, based at least in part on the one or more thresholds being satisfied, for each beam at one or more beam levels on one or more antenna panels, an application layer throughput, wherein the one or more beam levels are each associated with a number of antenna elements. The UE may generate a set of candidate beams that includes one or more beams for which the respective estimated application layer throughput satisfies an application layer throughput requirement. The UE may select a serving beam for which the estimated application layer throughput satisfies the application layer throughput requirement with a fewest number of antenna elements. Numerous other aspects are described.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to determine a PSD based on a transmission power associated with transmission of an uplink signal. The apparatus may be configured to select one of a first beam or a second beam for the transmission of the uplink signal based on the PSD. The second beam may be wider than the first beam, and may be generated by a single antenna element of the apparatus. The apparatus may be configured to transmit the uplink signal using the selected one of the first beam or the second beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may estimate, for each beam at one or more beam levels on one or more antenna panels, an application layer throughput based at least in part on a reference signal received power measurement, wherein the one or more beam levels are each associated with a number of antenna elements. The UE may generate a set of candidate beams that includes, at each of the one or more beam levels, one or more beams for which the respective estimated application layer throughput satisfies an application layer throughput requirement. The UE may select, from the set of candidate beams, a serving beam for which the estimated application layer throughput satisfies the application layer throughput requirement with a fewest number of antenna elements. 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 an available energy for uplink transmission of a plurality of communication links of the UE. The UE may configure, from the available energy, a first set of energy allocations for the plurality of communication links. The UE may configure a second set of energy allocations for one or more communication links of the plurality of communication links, wherein the second set of energy allocations are allocated from a remainder of the available energy after the first set of energy allocations are allocated. The UE may transmit based at least in part on at least one of the first set of energy allocations or the second set of energy allocations. Numerous other aspects are described.

Abstract: Techniques and apparatus for beam selection in compliance with radio frequency (RF) exposure limits. A method that may be performed by a wireless device includes receiving, from another wireless device, a plurality of signals via a plurality of beams; measuring a received signal power for each of the beams, based on the received plurality of signals; determining a transmit power limit for each of the beams based at least in part on an RF exposure limit; determining an estimation of a signal quality at the other wireless device for each of the beams based at least in part the received signal powers and the transmit power limits; selecting one of the beams based on the estimations of the signal qualities for the beams; and transmitting a signal via the selected beam.

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.
