Abstract: Disclosed in the present application is a method for transmitting a sounding reference signal (SRS) from a terminal to a base station in a time division duplex (TDD) system. More specifically, the method comprises: a step of establishing a first subframe set and a second subframe set through an upper layer, and step of transmitting the sounding reference signal from a specific subframe to the base station, wherein the first subframe set and the second subframe set are configured by an uplink subframe and/or a special subframe, each of the first subframe and the second subframe is associated with a power control process for transmitting an uplink data channel, and wherein the transmission power of the sounding reference signal is determined on the basis of a specific power control process associated with a subframe set to which the specific subframe belongs, from among the first subframe set and the second subframe set.
