Title:
METHOD FOR RECOVERING BEAM IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/164332
Kind Code:
A1
Abstract:
The present specification provides a method for recovering a beam in a wireless communication system. The method by which a terminal recovers a beam, in the present specification, can comprise the steps of: receiving, from a base station, a beam reference signal (BRS) to be used for beam management; transmitting a control signal for a beam recovery request to the base station, when a beam failure event is detected on the basis of the received BRS; and reporting, to the base station, a beam measurement result in a specific resource when beam reporting is triggered.
