|1. (WO2018203704) METHOD FOR PERFORMING BEAM RECOVERY IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR|
|Applicants:||LG ELECTRONICS INC.
|Title:||METHOD FOR PERFORMING BEAM RECOVERY IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR|
The present specification provides a method for beam recovery in a wireless communication system. In the present specification, a method for beam recovery, performed by a terminal, comprises the steps of: receiving a beam reference signal used for beam management from a base station; determining an uplink (UL) resource for transmitting a control signal associated with a beam failure recovery request when a beam failure event is detected, wherein the UL resource is type 1 resource indicating a resource associated with a physical random access channel (PRACH) configured for the beam failure recovery request or type 2 resource indicating a physical uplink control channel (PUCCH) resource; and transmitting the control signal to the base station in the determined UL resource.
