1. A method performed by a user equipment (UE), the method comprising:
sending a beam failure recovery request message including information regarding beam failure recovery and information regarding a new candidate beam to a first cell, wherein the information regarding the new candidate beam comprises a reference signal identifier indicating a specific beam as the new candidate beam, and the beam failure recovery request message is a medium access control (MAC) control element (CE);
monitoring, after sending the beam failure recovery request message, a response to the beam failure recovery request message exclusively via the new candidate beam of a second cell; and
receiving the response to the beam failure recovery request message via the new candidate beam from the second cell.
