Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform beam refinement procedures for a first set of beams and a second set of beams. The first set of beams corresponds to a first set of synchronization signal blocks (SSBs) of a serving cell and the second set of beams corresponds to a second set of SSBs of the serving cell. The UE may transmit a message indicating channel state feedback (CSF) including either a first power metric for the first set of SSBs or both the first power metric and a second power metric for the second set of SSBs. The power metric(s) included in the CSF may be based on a first refinement status for the first set of SSBs as well as a second refinement status for the second set of SSBs or the second power metric satisfying a threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a channel state information reference signal (CSI-RS) Layer 3 (L3) signal corresponding to a first cell. The UE may select, based at least in part on an angle of arrival (AoA) difference between a first AoA and a second AoA, a UE reception (Rx) beam for receiving the CSI-RS L3 signal, wherein the first AoA is associated with the CSI-RS L3 signal, and wherein the second AoA is associated with a communication corresponding to a second cell. The UE may receive the CSI-RS L3 signal using the UE Rx beam. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive synchronization signal block (SSB) measurement time configuration (SMTC) information that identifies a periodicity of a plurality of SSB measurement occasions. The UE may perform at least one of a radio resource management (RRM) operation or a beam management (BM) operation on a group of SSBs based at least in part on whether the plurality of SSB measurement occasions overlap all SSBs of the group of SSBs. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving control signaling indicating for the UE to monitor a set of multiple synchronization signal blocks during a first transmission time interval, determining a priority order of the set of multiple synchronization signal blocks based on a number of beam switch events that occur during the first transmission time interval exceeding a beam switch capability limit of the UE, performing a set of multiple beam measurements of at least a subset of the set of multiple synchronization signal blocks that occur during the first transmission time interval according to the priority order of the set of multiple synchronization signal blocks, and transmitting a beam report to a base station based on the set of multiple beam measurements.

Abstract: Methods, systems, and devices for dynamic monitoring modes for synchronization signal block (SSB) transmissions are described. A user equipment (UE) may monitor one or more first SSB transmission opportunities for SSB transmissions from a base station and determine an SSB failure rate. Based on the failure rate, the UE may select a mode for monitoring one or more second SSB transmission opportunities. For example, if the failure rate is greater than a threshold, the UE may select a first mode for monitoring a first quantity of the one or more second SSB transmission opportunities. Additionally, if the failure rate is less than the threshold, the UE may select a second mode for monitoring a second quantity different than the first quantity of the one or more second SSB transmission opportunities. The UE may monitor the one or more second SSB transmission opportunities according to the selected mode for monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a measurement procedure for beam detection within an existing cell. The UE perform a search procedure for a first synchronization signal block (SSB) to detect a first beam of a base station. The UE may determine a first timing offset for the first SSB based on the search procedure. The UE may estimate a second timing offset for a second SSB from the base station based on the first timing offset. The UE may perform a measurement procedure for the second SSB to detect a second beam of the base station based on the second timing offset. The UE may prune fake beams based on synchronization signals used for the measurement procedure.
