According to one embodiment of the present invention, a method by which a terminal transmits a sounding reference signal (SRS) in a wireless communication system supporting a time divisional duplex (TDD) comprises the steps of: receiving TC information indicating any one of a total of four TCs supported by a 4-transmission comb (TC) SRS; mapping the 4-TC SRS to an SRS symbol of an uplink pilot time slot (UpPTS) of a TDD special subframe on the basis of the TC information; and transmitting the 4-TC SRS through the UpPTS, wherein, in the step of mapping the 4-TC SRS, the 4-TC SRS is mapped by a unit of one RE per four REs on the SRS symbol on the basis of the TC indicated by the TC information, and the transmission of the 4-TC SRS is supported when a plurality of symbols are set to the UpPTS. |
