A communication method for a terminal in a communication system which supports the combination of configuration carrier using FDD scheme and configuration carrier using TDD scheme, in accordance with an embodiment of the present invention, comprises the steps of: receiving SRS transmission setting information from a base station; receiving uplink data scheduling information from the base station; determining whether or not the simultaneous transmission of the SRS transmission and the uplink data occurs; and setting the transmission of the uplink data or the SRS so that when the simultaneous transmission of the SRS transmission and the uplink data occurs, the sum of the respective transmission powers of the first and second symbols in an FDD cell and the first and second symbols of a TDD cell is not greater than the maximum transmission power of the terminal, wherein the timing of the first symbol in the FDD cell corresponds to the timing of the first symbol in the TDD cell, and the timing of the second symbol in the FDD cell corresponds to the timing of the second symbol in the TDD cell. In accordance with an embodiment of the present invention, defining the SRS transmission method of the terminal in a wireless communication system causes the terminal to effectively transmit the uplink data.
