Classification: CPC H | IPC H

Claim 8:
9. A terminal for transmitting a beam failure recovery request, the terminal comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
receive, 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,
select a reference signal of which reference signal received power (RSRP) is greater than a predetermined threshold from among the at least one reference signal,
identify 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,
transmit, to the base station, a random access preamble for a beam failure recovery request based on the identified resource,
monitor a downlink control channel based on the search space identified by the information on the search space for the beam failure recovery response, and
receive, from the base station, the beam failure recovery response on the downlink control channel.
