Title:
METHOD AND APPARATUS FOR PERFORMING COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/249328
Kind Code:
A1
Abstract:
Disclosed is a 5th generation (5G) or 6th generation (6G) communication system for supporting higher data rates after a 4th generation (4G) communication systems such as long term evolution (LTE). An operating method of a base station includes receiving, from a user equipment (UE), information about channel state information (CSI) measured based on a first CSI-reference signal (RS), determining, based on the information about the CSI, one autoencoder (AE), from among a plurality of AEs, transmitting, to the UE, information indicating an encoder included in the determined AE, transmitting a second CSI-RS to the UE, receiving, from the UE, CSI compressed based on CSI measured using the second CSI-RS and the indicated encoder, and performing reconstruction based on the compressed CSI and a decoder included in the determined AE.
