Title:
METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/063655
Kind Code:
A1
Abstract:
A method and a device for transmitting or receiving a wireless signal in a wireless communication system are disclosed. A method for reporting channel state information (CSI) by a terminal according to an embodiment of the present disclosure may comprise the steps of: receiving at least one reference signal (RS) for the CSI reporting from a base station; inputting information related to the at least one reference signal to an artificial intelligence (AI) model to obtain the result of channel estimation; and transmitting the CSI to the base station on the basis of the result of the channel estimation, wherein the AI model comprises multiple parameter sets, and the size of each of the multiple parameter sets may be based on information related to a downlink (DL) channel scheduled by the base station or information related to a predefined resource group.
