A method for transmitting an SRS resource by a terminal when all cyclic shifts (CSs) of a sounding reference signal (SRS) resource are not used for SRS comprises the steps of: receiving information on the usage of a CS that is not used for a SRS; receiving information on an SRS resource index, a CS index that is not used for the SRS, and a usage specifying index; and transmitting the SRS resource by using the CS index, wherein the usage of the SRS resource is determined on the basis of information on the usage of the CS and the usage specifying index.
