BEAM RECOVERY METHOD IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR

Title:

BEAM RECOVERY METHOD IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/050380

Kind Code:

A1

Abstract:

The present specification provides a beam failure recovery method in a wireless communication system. The beam failure recovery method performed by a terminal, according to the present specification, comprises the steps of: receiving, from a base station, control information associated with a candidate beam configuration for beam failure recovery; selecting, from RSs associated with identifying the candidate beam, an RS having a quality level that is at least a threshold value; and transmitting a beam failure recovery request to the base station on the basis of an uplink (UL) resource associated with the selected RS.
