Title:
METHOD FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2020/040539
Kind Code:
A1
Abstract:
A method by which a terminal reports channel state information in a wireless communication system. Particularly, a method by which a terminal transmits power measurement information related to beam reporting in a wireless communication system comprises the steps of: receiving downlink control information (DCI) triggering the reporting of the power measurement information; receiving a downlink reference signal for reporting the power measurement information; and transmitting, to a base station, the power measurement information determined on the basis of the received downlink reference signal, wherein the minimum required time for the reporting of the power measurement information i) can be calculated as the sum of a first minimum required time from the last time of the downlink reference signal to the transmission time of the power measurement information and a second minimum required time between the receptions of the DCI triggering the downlink reference signal and the downlink reference signal or ii) can be calculated on the basis of a preset threshold value related to the reporting of the power measurement information.
