Claim Text:
1. A method for transmitting an aperiodic sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system, the method comprising: receiving separate periodic and aperiodic SRS power offset parameters for a periodic SRS and an aperiodic SRS, respectively, from a base station (BS) through a radio resource control (RRC) signaling; receiving common parameters for both the periodic SRS and the aperiodic SRS from the BS through the RRC signaling; setting transmission powers of the periodic SRS and the aperiodic SRS based on the periodic and aperiodic SRS power offset parameters, respectively, and the common parameters; and transmitting the periodic SRS and the aperiodic SRS to the BS based on the transmission powers of the periodic SRS and the aperiodic SRS, respectively, wherein the periodic SRS power offset parameters are non-common parameters used for transmitting the periodic SRS but not the aperiodic SRS, and the aperiodic SRS power offset parameters are non-common parameters used for transmitting the aperiodic SRS but not the periodic SRS.
