Title:

METHOD BY WHICH TERMINAL REPORTS STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND TERMINAL AND BASE STATION FOR SUPPORTING SAME

Document Type and Number:

WIPO Patent Application WO/2020/159189

Kind Code:

A1

Abstract:

Disclosed are: a method by which a terminal reports state information, relating to one or more cells from among a plurality of cells set in the terminal, in a wireless communication system including the terminal and a base station having the plurality of cells; and a terminal and a base station for supporting same. According to one embodiment applicable to the present disclosure, a terminal can efficiently report, to a base station, state information related to one or more cells in which beam failure has occurred and, in response thereto, the base station can recognize the beam failure in the one or more cells.
