Claim 0:
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a reference signal on a downlink beam;
generating beam related information for reporting a failure of the downlink beam, in case that a beam failure is detected based on the reference signal; and
in case that a beam correspondence is satisfied and a plurality of beam pairs are configured for the terminal, transmitting, to the base station on a beam of a beam pair, the beam related information on a physical uplink control channel (PUCCH) for periodic reporting of a beam measurement result,
wherein the beam measurement result includes a measurement value and a differential value associated with the downlink beam, and a beam index of the downlink beam,
wherein the beam related information indicates that the beam failure is detected and includes a scheduling request (SR), and
wherein whether the beam correspondence is satisfied is determined based on the beam measurement result.
