Method and apparatus for reporting beam information in next-generation communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a reference signal on a downlink beam;
• and
• in case that a beam correspondence is satisfied and a plurality of beam pairs are configured for the terminal, receiving, from the terminal on a beam of a beam pair, beam related information on a physical uplink control channel (PUCCH) for periodic reporting of a beam measurement result,
• wherein the beam related information is for reporting a failure of the downlink beam, in case that a beam failure is detected based on the reference signal,
• 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.

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.
