Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, for each of one or more candidate beams in a set of candidate beams, a downlink throughput, an uplink throughput, a downlink power consumption, and an uplink power consumption. The UE may select a beam based at least in part on: at least one of the downlink throughput or the uplink throughput, at least one of the downlink power consumption or the uplink power consumption, and one or more throughput thresholds. The UE may communicate using the selected 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 first transmit power limit based at least in part on at least one of a specific absorption rate limit, a maximum permissible exposure limit, or a power density limit. The UE may modify, based at least in part on a scaling factor associated with a time interval, the first transmit power limit to obtain a modified first transmit power limit. The UE may transmit a signal based at least in part on the modified first transmit power limit. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may select a set of candidate UE beams for measuring channel state information (CSI) reference signal (CSI-RS) based on one or more power measurements for uplink transmissions. The UE may measure multiple synchronization signal blocks (SSBs) using the set of candidate UE beams and select a subset of the selected candidate beams based on the SSB measurements. The UE may measure spectral efficiency via the resource carrying the CSI-RS using the subset of candidate UE beams and select a serving beam from the subset based on the spectral efficiency of each beam. The UE may calculate the power measurements based on a difference between a power threshold and a reference power value for each candidate 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 receive an antenna switch selection associated with a dual connectivity antenna configuration, wherein the antenna switch selection is associated with a first radio access technology (RAT) and the dual connectivity antenna configuration permits communication via the first RAT and a second RAT; determine, based at least in part on the antenna switching selection, a quantity of communication chains, associated with the first RAT, that are affected by an antenna switching process of the second RAT; and selectively permit, based at least in part on the quantity of communication chains, a reconfiguration of the dual connectivity antenna configuration according to the antenna switch selection.

Abstract: Certain aspects of the present disclosure provide techniques for detecting power consumption conditions to trigger transmission of user equipment (UE) assistance information (UAI) for a reconfiguration request. For example, an example method by a UE generally includes detecting one or more conditions associated with at least one metric related to UE power consumption; and transmitting UAI to a network entity, in response to the detection, to request a reconfiguration of the UE to operate according to a set of one or more parameters selected based on a value of the at least one metric.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with other network devices as part of a wireless communications system. The UE may identify a blockage corresponding to one or more antenna arrays of a set of antenna arrays based on using a first set of beam weights, which may correspond to a static beamforming codebook of the one or more antenna arrays. The UE may switch from a static beamforming codebook-based beam weight determination to a dynamic beamforming codebook-based beam weight determination. The UE may then determine a second set of beam weights to use for the one or more antenna arrays based on the dynamic beamforming codebook-based beam weight determination. The UE may then communicate using the one or more antenna arrays according to the second set of beam weights.
