Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a cell search using a first set of beams. The UE may determine a channel condition value based at least in part on performing the cell search. The UE may modify the channel condition value based at least in part on at least one of: the first set of beams used to perform the cell search, a beam selected from the first set of beams, or a second set of beams that is different from the first set of beams and that is included in a beamforming codebook associated with the UE. The UE may transmit a measurement report that includes the modified channel condition value. Numerous other aspects are provided.

Abstract: A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may determine a plurality of antenna configurations for a plurality of channel frequencies. The UE may determine a set of signal strengths for at least one beam received at one or more antenna configurations of the plurality of antenna configurations for at least one of the channel frequencies.

Abstract: A method of wireless communication includes receiving, by a UE, one or more configuration messages indicating synchronization signals (SS) and physical broadcast channel (PBCH) block measurement timing configuration (SMTC) parameters. The SMTC parameters indicate SMTC windows associated with reception of synchronization signal blocks (SSBs) by the UE from a base station. The method further includes, based on detecting one or more trigger conditions, transitioning, by the UE, from an inactive state to an active state to receive, during a time interval distinct from the SMTC windows, one or more SSBs from the base station. The method further includes performing, by the UE, one or more beam management operations based on the one or more SSBs received during the time interval.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may determine a set of scheduled synchronization signal transmission times. A first subset of the set of scheduled synchronization signal transmission times may be allocated for dynamic measurement. The wireless device may select at least one candidate beam from a set of candidate beams for a dynamic measurement during one of the transmission times in the first subset. The at least one candidate beam may be selected based at least in part on a fairness metric, a signal strength metric, a timing metric, or a combination thereof. The wireless device may perform a measure procedure on the selected at least one candidate beam and may transmit a measurement report based at least in part on the measure procedure to another wireless device (e.g., a base station).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a first set of throughput targets and a second set of throughput targets for an application layer. The UE may set a target throughput rate associated with the application to a required throughput target included in the first set of throughput targets. The UE may monitor a real-time throughput rate associated with the application layer. The UE may set the target throughput rate to a value in the second set of throughput targets based at least in part on a difference between the real-time throughput rate and the required throughput target satisfying a threshold. The UE may select, from a set of candidate beams, a serving beam associated with an estimated application layer throughput that satisfies the target throughput rate. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE implements the technique to select a number of component carriers (CCs) in both a first frequency range and a second frequency range. The UE determines a schedule for performing search and measurement in the selected number of CCs. The UE performs search and measurement in the selected CCs according to the determined schedule.

Abstract: A UE determines a default beam for a physical downlink shared channel (PDSCH) that is independent of a beam for a physical downlink control channel (PDCCH). The default PDSCH beam may be determined based on information received in a medium access control-control element (MAC-CE), or a radio resource control (RRC) message, a downlink control information (DCI). The default PDSCH beam may be determined based on at least one active transmission configuration indication (TCI) state for the PDSCH.

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: Certain aspects of the present disclosure relate to beam selection. An example method generally includes selecting, from a plurality of beams, a beam for transmission during a particular time interval within a time window, the selecting being based on a transmission power and a radio frequency (RF) exposure for each of the plurality of beams and transmitting at least one signal using the selected beam during the particular time interval.
