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 failureevent 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.

Description

[0001] Cross References to Related Applications [0002] This application is a national phase filing of International Application No. PCT / KR2017 / 009084 filed on August 21, 2017 under U.S.C. Rule 35, Item 371, requesting U.S. Provisional Application No. filed on March 9, 2017 .62 / 469,507, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates to a wireless communication system, and more particularly, to a method for performing beam restoration and an apparatus supporting the method. Background technique [0004] Mobile communication systems are generally developed to provide voice services while ensuring user mobility. Such mobile communication systems have gradually expanded their coverage from voice services to data services, and up to high-speed data services. However, since current mobile communication systems suffer from resource shortage and users demand even higher-speed services, m...
