Patent ID: 11881987
Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A terminal in a communication system, comprising:
a processor,
wherein the processor causes the terminal to:
search for a plurality of candidate beams when a beam failure is detected;
transmit a first beam failure recovery request signal to a base station using a beam #1 among the plurality of candidate beams;
receive from the base station a first beam failure recovery response signal that is a response to the first beam failure recovery request signal through the beam #1;
when a beam failure recovery procedure for the beam #1 is succeed, perform a multi-beam configuration procedure for a beam #2 among the plurality of candidate beams; and
perform communication with the base station using multi-beam including the beam #1 and the beam #2,
wherein, when the multi-beam configuration procedure is performed, the processor causes the terminal to:
transmit a second beam failure recovery request signal to the base station using the beam #2 among the plurality of candidate beams; and
receive from the base station a second beam failure recovery response signal that is a response to the second beam failure recovery request signal through the beam #2.
