    Abstract: Certain aspects of the present disclosure provide techniques for per-rank uplink and downlink beam selection. An example method, performed at a user equipment (UE), generally includes measuring channel state information (CSI) reference signals (CSI-RS) associated with a plurality of beams, determining an uplink rank and a downlink rank, selecting, from the plurality of beams, a downlink beam for processing downlink transmissions, based on the CSI RS measurements and the downlink rank, and selecting, from the plurality of beams, an uplink beam for processing uplink transmissions, based on the CSI RS measurements, the uplink rank, and the downlink rank.

    Abstract: Methods and apparatus for beam management where a beam is selected based on an estimated channel correlation matrix. The apparatus determines a channel correlation matrix based on downlink SSB reference signal received at the UE. The apparatus estimates a RSRP of a plurality of beams associated with an uplink channel based on the channel correlation matrix and associated beam weights. The apparatus selects a first beam from the plurality of beams having a highest estimated RSRP for communication with a base station. The apparatus communicates with the base station via the first beam.

    Abstract: In some aspects, the present disclosure provides methods, apparatuses, and systems for efficient thermal mitigation while maintaining wireless device performance on a primary component carrier (PCC). Embodiments described may include implementation of target transceiver module configurations, where bandwidth (e.g., PCC bands and secondary component carrier (SCC) bands) may be monitored by a wireless device based on intra-module target configurations and/or inter-module target configurations. An intra-module target configuration may include a target transceiver module monitoring both PCC bands and SCC bands. An inter-module target configuration may include or refer to a plurality of target transceiver modules together monitoring PCC bands and SCC bands. In scenarios where operating temperatures exceed temperature thresholds, target transceiver module configurations may be implemented to transition PCC bands, SCC bands, or both, from a PCC-resident transceiver module to another transceiver module to reduce the operating temperatures of concern. Various additional and alternative aspects are described herein.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a monitoring signal associated with one or more antennas. The UE may identify, based at least in part on the monitoring signal, a blockage associated with the one or more antennas. The UE may perform a beam search using a decreased frequency of occurrence of tracking occasions for the one or more antennas based at least in part on the identification of the blockage associated with the one or more antennas. Numerous other aspects are provided.

    Abstract: A first wireless device may select a first beam for communication with a second wireless device from a first set of beams associated with a first beam level. A second set of beams may be associated with a second beam level. The first beam may be associated with a first children list. The first children list may be associated with a first subset of beams of the second set of beams. Each beam in the first subset of beams may have an envelope area that intersects an envelope area of the first beam. The first wireless device may select a second beam for communication with the second wireless device from the first subset of beams based on an envelope area of the second beam intersecting the envelope area of the first beam. The first wireless device may communicate with the second wireless device.
