Title: Method for transmitting and receiving channel state information in wireless communication system and device for the same
IPC: H04W8/22
Filed: 2022-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a method of transmitting, by UE, power measurement information related to beam reporting. 
     SOLUTION: A method includes a step of transmitting, to a base station, a report of power measurement information determined based on a received downlink reference signal. On the basis of reporting of the power measurement information being set for an L1-RSRP report, a minimum required time for reporting of the power measurement information is determined on the basis of a first timing parameter related to a first time section from the last timing of the downlink reference signal to a transmission timing of reporting the power measurement information and a second timing parameter related to a second time section from timing of triggering DCI to timing of the downlink reference signal. When the second timing parameter has a value of 14, the minimum required time is calculated as the sum of the first timing parameter and the second timing parameter; when the second timing parameter has values of 224 and 336, the minimum required time is determined regardless of the second timing parameter.
