1. A method for transmitting a sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving configuration information related to transmission of the SRS;
receiving downlink control information (DCI) which triggers transmission of the SRS; and
transmitting the SRS,
wherein the SRS is based on both of a first SRS and a second SRS, the second SRS being configured in a time resource region different from the first SRS,
wherein the first SRS is configured in 4 symbols of a special subframe,
wherein the second SRS is configured in one or more symbols other than a last symbol of a normal Uplink (UL) subframe excluding the special subframe,
wherein, based on the SRS being the second SRS, the normal UL subframe in which the second SRS is transmitted is determined based on a UE-specific configuration related to a transmission timing of the first SRS, and
wherein the UE-specific configuration is related to a transmission periodicity and a transmission offset of the first SRS.
