PROBLEM TO BE SOLVED: To apply optimal transmission power control to each of a periodic SRS and aperiodic SRS.SOLUTION: A mobile station device is applied to a radio communication system which comprises a base station device and a mobile station device, and in which the mobile station device transmits a first reference signal or second reference signal among a plurality of reference signals to the base station device. The mobile station device comprises: a reception unit 205 for receiving a first parameter that is used for transmission power control of the first reference signal and that is set by the base station device, and a second parameter that is used for transmission power control of the second reference signal and that is set by the base station device; an upper-level layer processing unit 201 for performing transmission power control of the first reference signal using the first parameter, and on the other hand for performing transmission power control of the second reference signal using the second parameter; and a transmission unit 207 for transmitting the first reference signal and/or second reference signal that has gone through the transmission power control to the base station device.SELECTED DRAWING: Figure 7 |
