METHOD AND APPARATUS FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM

原文（中国語）

Provided is a 5th-generation (5G) or 6th-generation (6G) communication system for supporting higher data rates after the 4th-generation (4G) communication system such as long term evolution (LTE). According to an embodiment of the disclosure, a user equipment (UE) may compress channel state information (CSI) data estimated between a base station (BS) and the UE through an artificial intelligence (AI) model for encoding trained in association with an AI model for decoding in the BS, transmit the compressed CSI data to the BS, transmit, to the BS, the CSI data on which the compression is not performed, based on a preset condition, and receive information for updating the AI model for encoding when the BS determines to update the AI model for encoding based on the CSI data.
