Abstract
Optimal transmit power control is performed on each of a periodic SRS and an aperiodic SRS. In a radio communication system in which a mobile station apparatus 1 transmits a first reference signal or a second reference signal to a base station apparatus 3, the base station apparatus 3 notifies the mobile station apparatus 1 of a first parameter used for setting of a transmit power for transmission of the first reference signal, and a second parameter used for setting of a transmit power for transmission of the second reference signal, and the mobile station apparatus 1 sets the transmit power for transmission of the first reference signal using the first parameter, while setting the transmit power for transmission of the second reference signal using the second parameter.
