Title:
METHOD FOR TRANSMITTING CHANNEL QUALITY INDICATOR IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/019423
Kind Code:
A1
Abstract:
The present disclosure relates to a method by which a user equipment (UE) transmits predicted channel status information (CSI) to a base station (BS) in a wireless communication system. Specifically, the method comprises the steps of: receiving at least one channel measurement resource (CMR) from the BS; calculating precoding matrix indexes (PMIs) for two or more time instances on the basis of the at least one CMR; calculating a first channel quality indicator (CQI) for a first time instance on the basis of the PMI for the first time instance from among the two or more time instances; calculating a second CQI for a second time instance on the basis of the PMI for the second time instance from among the two or more time instances; and transmitting the predicted CSI including the first CQI and the second CQI to the BS, wherein the second time instance is determined on the basis of the number of time instances.
