Claim 0:
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, 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;
selecting a reference signal of which reference signal received power (RSRP) is greater than a predetermined threshold from among the at least one reference signal;
identifying a resource corresponding to the selected reference signal based on an association between the at least one reference signal and at least one beam failure recovery request resource;
transmitting, to the base station, a random access preamble for a beam failure recovery request based on the identified resource;
monitoring a downlink control channel based on the search space identified by the information on the search space for the beam failure recovery response; and
receiving, from the base station, the beam failure recovery response on the downlink control channel.
