1. A method for transmitting a sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a higher layer message including configuration information including a number of times of transmission of an aperiodic SRS (AP-SRS), a subframe in which a periodic SRS is transmitted, and an AP-SRS subframe offset of the AP-SRS related to the subframe in which the periodic SRS is transmitted;
performing a first transmission of a periodic SRS based on the configuration information;
receiving downlink control information (DCI) triggering a second transmission of the AP-SRS; and
in response to the DCI, stopping the first transmission of the periodic SRS, and performing the second transmission of the AP-SRS in a plurality of subframes based on the configuration information.
