Abstract: A method of user equipment may comprise: determining whether an error condition for a first beam communicating with a base station is met; when it is determined that the error condition for the first beam is met, determining whether a first physical uplink control channel (PUCCH) allocated to the user equipment is present within a predetermined first period of time; when it is determined that the first PUCCH is not present, transmitting a sounding reference signal (SRS) transmission approval request and an identifier of the user equipment to the base station through a second PUCCH pre-configured to be shared by all pieces of user equipment; and when an SRS transmission approval is received from the base station, transmitting an SRS to the base station.
