PROBLEM TO BE SOLVED: To efficiently perform transmission of a first reference signal for channel measurement, transmission of a second reference signal, and transmission over a physical uplink control channel.SOLUTION: A mobile station device transmits a first reference signal to a base station device when information indicating transmission of the first reference signal is included in a physical downlink control channel, transmits a second reference signal to the base station device according to information included in a radio resource control signal and indicating transmission of the second reference signal. According to information permitting simultaneous transmission, the first reference signal is transmitted when the transmission of the first reference signal and the transmission of the second reference signal are set to the same timing and the same radio resource is used, or the first reference signal and the second reference signal are transmitted to the base station device when the transmission of the first reference signal and the transmission of the second reference signal are set to the same timing and difference radio resources are used. |
