1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
transmitting, to a base station, capability information including information indicating whether a selection of an uplink transmission beam of the UE without an uplink beam sweeping is available in the UE or not;
receiving, from the base station, configuration information for a sounding reference signal (SRS); and
transmitting, to the base station, one or more SRSs using one or more uplink transmission beams of the UE based on the configuration information,
wherein, in case that the selection of the uplink transmission beam of the UE without the uplink beam sweeping is unavailable, the capability information is associated with a number of SRSs for an uplink beam search in the configuration information.
