US 12,587,249 B2 · Method and apparatus for frequency selective beam measurement and reporting

Abstract

Methods and apparatuses for frequency selective beam measurement and reporting (FSBMR) in a wireless communication system. A method for operating a user equipment (UE) includes receiving a configuration for a channel state information (CSI) reference signal (RS) resource and a CSI reporting setting to enable FSBMR. The method further includes receiving first information indicating a first set of frequency subbands for the CSI-RS resource and receive second information indicating a second set of frequency subbands for the CSI reporting setting. The method further includes measuring, based on the configuration and the first information, the CSI-RS resource and determining, based on the configuration, the measurement, and the second information, a beam report including one or more beam metrics.
