초록
Provided are a method and a device for triggering a beam failure recovery (BFR) procedure of a multibeam system by means of the steps of: detecting a beam failure by monitoring a wireless link connected with a base station; identifying a candidate transmission beam of the base station; and transmitting a BFR request to the base station when the candidate transmission beam of the base station is identified.
