Provided in the present invention are a method performed by user equipment, and user equipment, which can reliably perform processing related to a beam failure recovery request/beam failure report (BFR) and/or scheduling request (SR). The method comprises: detecting a measurement result of a measurement reference signal corresponding to a serving cell; if the measurement result indicates that a beam failure has occurred, utilizing a counter to count the number of beam failures; and when the count value of the counter is above a given threshold, performing processing related to a beam failure recovery request/beam failure report (BFR) and/or scheduling request (SR).

A system for transmitting and receiving radio signals is disclosed. The system includes a controller having a modem and a transmission amplifier module connected to the modem, an antenna unit arranged at a distance from the controller and having an antenna and a reception amplifier module connected to the antenna, and a high-frequency cable connecting the controller and the antenna unit.

A method for determining beam failure recovery, a terminal device, and a non-transitory computer-readable storage medium are provided. The method includes in a case of a beam failure, initiating a contention-based random access process triggered for beam failure recovery. The method further includes receiving a downlink response message and determining that the beam failure recovery is completed. The downlink response message is a response message corresponding to the random access process.
