Claim Text:
1. A method of controlling a sounding reference symbol (SRS) transmission by a user equipment (UE) in a wireless communication system supporting a plurality of component carriers, the method comprising: when a sounding reference symbol (SRS) transmission on a first timing advance group is scheduled in a subframe, and a physical uplink control channel (PUCCH) transmission and a physical uplink shared channel (PUSCH) transmission on a second timing advance group are scheduled in the subframe, transmitting the PUCCH and PUSCH in the subframe of the second timing advance group; and dropping the SRS in the subframe of the first timing advance group when the SRS transmission in the subframe of the first timing advance group overlaps the PUCCH transmission and PUSCH transmission on the second timing advance group in a time domain and a total transmission power of the UE exceeds a maximum transmission power configured for the UE in the overlapped portion.
