Claim 4:
5. A method performed by a base station for a beam failure recovery, the method comprising:
transmitting, to a terminal, information on a list of at least one candidate reference signal;
receiving, from a terminal, a media access control (MAC) control element (CE) for a beam failure recovery including a field Ci set to 1 indicating that the beam failure is detected on a secondary cell (SCell) with an index i, and information on a reference signal from the list of the at least one candidate reference signal; and
transmitting, to the terminal, a response of the beam failure recovery,
wherein the information on the reference signal comprises information on a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) with a reference signal received power (RSRP) above a threshold, and
wherein the MAC CE for the beam failure recovery is identified by a logical channel identifier (LCID) in a MAC subheader.
