METHOD AND APPARATUS FOR TRANSCEIVING CSI FEEDBACK IN CELLULAR SYSTEMS

WIPO Patent Application WO/2024/063536

A1

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Method and apparatuses for channel state information (CSI) feedback in cellular systems. A method for operating a user equipment (UE) to report CSI includes transmitting first information related to a capability of the UE to support machine learning (ML) based CSI reporting and second information related to a selection of a ML model for CSI reporting, receiving third information related to configuring a first ML model for determining the CSI, fourth information related to processing a ML model output, fifth information related to reception of CSI reference signals (CSI-RSs) on a cell, and the CSI-RSs based on the fifth information, and determining, based on the third and fourth information and the reception of the CSI-RSs, a CSI report using the first ML model and transmitting a channel with the CSI report.
