CHANNEL STATE INFORMATION REPORTING METHOD OF TERMINAL BASED ON POWER CONTROL OF UPLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND TERMINAL AND BASE STATION SUPPORTING SAME

摘要

Disclosed are a channel state information reporting method of a terminal related to beam management (BM), and a terminal and base station supporting same. According to an embodiment applicable to the present disclosure, a terminal may receive physical uplink control channel (PUCCH) power control information for PUCCH transmission from a base station and report, to the base station, channel state information including beam quality information determined on the basis of configuration of the base station, via a PUCCH determined on the basis of the PUCCH power control information. In response, the base station may control one or more beams providing a service to the terminal by using the reported channel state information.
