Claim 8:
9. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit or receive a signal; and
a controller coupled with the transceiver configured to:
receive, from a base station, a reference signal on a downlink beam,
generate 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, transmit, 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.
