摘要： 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.

摘要： 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.

摘要： Certain aspects of the present disclosure provide techniques for communicating antenna module information, beamforming capabilities, power control information, etc., for computing devices capable of operating in multiple form factor configurations. A example technique includes detecting that the UE is operating in a first form factor configuration of a plurality of form factor configurations the UE is adapted to operate in. The technique also includes, in response to the detection, transmitting information associated with at least one antenna module of the UE in the first form factor configuration.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a channel matrix of the UE. The UE may identify a set of beam weights according to the channel matrix. The UE may identify a set of beam properties based at least in part on an index, wherein the index is based at least in part on the set of beam weights, and wherein the index is identified without storing the set of beam weights in a long-term memory of the UE. The UE may generate a beam using the set of beam properties. Numerous other aspects are described.

摘要： A method of wireless communication by a user equipment (UE) includes determining a first synchronization signal block (SSB) to monitor beam management. The first SSB comprises a primary synchronization signal (PSS), multiple physical broadcast channels (PBCHs), and a secondary synchronization signal (SSS). The method also includes determining a list of receive beams for measuring the first SSB. The method further includes measuring the first SSB by measuring the PSS with a first beam from the list of receive beams, measuring, with a second beam from the list of receive beams, a first demodulation reference signal (DMRS) on a first PBCH symbol of a first of the PBCHs, measuring the SSS with a third beam from the list of receive beams; and measuring, with a fourth beam from the list of receive beams, a second DMRS on a second PBCH symbol of a second of the PBCHs.

摘要： 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.
