Abstract:
A method for transmitting signals by a medium access control (MAC) entity of a transmission end in a wireless communication system is disclosed. The method comprises initializing a random access procedure on a secondary cell for beam failure recovery (BFR); transmitting an indication for requesting at least one suitable beam to a lower layer; if information about the at least one suitable beam is not received from the lower layer, incrementing a random access preamble transmission counter; and when the random access preamble transmission counter is less than a maximum value, retransmitting the indication for requesting the at least one suitable beam to the lower layer.
