Abstract

A method and apparatus are provided for transmission of a sounding reference signal (SRS) in an uplink wireless communication system with a multi-carrier transmission scheme. A user equipment terminal receives a subframe offset among component carriers of an uplink channel from a base station. Then the user equipment terminal determines a particular subframe configured for transmission of the SRS in the respective component carriers, depending on the subframe offset. The user equipment terminal assigns the SRS to the component carriers corresponding to the particular subframe, and transmits the particular subframe to the base station. Since the subframe offset among component carriers may be changed, every user equipment terminal may cope flexibly with variable conditions such as channel states and power limitations.
