Document Type and Number:
WIPO Patent Application WO/2020/060346
Kind Code:
A1
Abstract:
A method for transmitting and receiving channel state information (CSI) in a wireless communication system and an apparatus therefor are disclosed. Specifically, a method, performed by a user equipment (UE), for reporting channel state information (CSI) in a wireless communication system comprises the steps of: receiving, from a base station, CSI reporting-related setting information; setting reporting with respect to at least one of aperiodic CSI, periodic CSI, and semicontinuous CSI, on the basis of the CSI reporting-related setting information, and calculating first information and second information with respect to channel quality, on the basis of the CSI reporting-related setting information; and transmitting, to the base station, CSI on the basis of the first information and the second information, the first information being calculated by applying a precoding matrix indicator (PMI) included in the latest CSI that is aperiodically reported, and the second information being calculated by a PMI at a time point of the calculating of the second information, wherein the CSI may correspond to the periodic CSI or the semicontinuous CSI.
