Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure one or more radio frequency (RF) chains of the UE to communicate using a second radio access technology (RAT) for a length of time. The UE may identify that the length of time satisfies a threshold. The UE may configure the one or more RF chains to the first RAT. The UE may initiate a beam measurement on the first RAT in a number of consecutive measurement occasions based at least in part on the length of time satisfying the threshold. Numerous other aspects are described.

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: Techniques for managing base station beam panic for new radio technologies may include a user equipment (UE) measuring a signal quality of a serving beam from a base station. The UE may determine the signal quality has decreased by at least a threshold amount, and enable a signal panic operation to search for a beam different from the serving beam, in response to the signal quality decreasing by at least the threshold amount.

Abstract: A UE may calculate an allocation of a transmission power for a first uplink transmission on a first uplink channel and at least one second uplink transmission on at least one second uplink channel, the transmission power being allocated in each symbol of a plurality of symbols in a slot. The UE may detect a transmission power change in the allocation of the transmission power in the slot for at least one of the first uplink transmission or the at least one second uplink transmission. The UE may determine whether to adjust the allocation of the transmission power for the at least one of the first uplink transmission or the at least one second uplink transmission to eliminate the transmission power change in the slot for the at least one of the first uplink transmission or the at least one second uplink transmission.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a minimum slot offset based at least in part on a determination of a minimum wake-up signal (WUS) gap capability associated with the UE, wherein the minimum WUS gap capability corresponds to a capability of the UE to support a WUS gap having a minimum gap size, wherein the minimum slot offset indicates a minimum time period between a physical downlink control channel (PDCCH) occasion and a physical downlink shared channel (PDSCH) occasion scheduled by the PDCCH; and monitor the PDCCH occasion for a downlink grant based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to a user equipment (UE) configured to schedule resource management procedures including measurements and tracking loop procedures. In some examples, the UE includes at least one antenna pair and two or more receivers. The UE may be configured to determine a plurality of combinations of antenna pairs and component carriers, where each component carrier is associated with a particular frequency. The UE may further be configured to schedule measurements/tracking loop procedures to available receivers first and utilize a selection algorithm to select combinations of antenna pairs and component carriers and map the selected combinations to the remaining of the available receivers to perform tracking loop procedures. Other aspects, features, and embodiments are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select two transmit beams from a plurality of beams that the UE is capable of forming using an antenna array of the UE that includes a plurality of antenna elements, wherein the two transmit beams are to be used to transmit two corresponding layers of information; determine, after selecting the two transmit beams, a phase difference to be applied to the two transmit beams based at least in part on the two transmit beams; and transmit the information on the two corresponding layers concurrently via the two transmit beams using the phase difference. Numerous other aspects are provided.
