  • Patent number: 11968015
    Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.
