Classification: CPC H | IPC H

Claim 4:
5. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, configuration information including information on at least one reference signal to be used for identifying at least one candidate beam for beam failure recovery and information on a search space for a beam failure recovery response;
receiving, from the terminal, a random access preamble for a beam failure recovery request, based on a resource corresponding to a reference signal selected by the terminal of which a reference signal received power (RSRP) is greater than a predetermined threshold from among the at least one reference signal; and
transmitting the beam failure recovery response on a downlink control channel based on the search space identified by the information on the search space for the beam failure recovery response,
wherein the resource is identified, by the terminal, based on an association between the at least one reference signal and at least one beam failure recovery request resource.
