PROBLEM TO BE SOLVED: To achieve more flexible scheduling and throughput improvement by creating an SRS (Sounding Reference Signal) transmission resource according to the determination of a base station device in each case, even when a resource for transmitting an SRS is not secured beforehand, regarding transmission of aperiodic SRS. SOLUTION: A wireless communication system transmits a reference signal for channel measurement from a mobile station device 3 to a base station device 1. The base station device 1 transmits, to the mobile station device 3, an uplink allocation signal including an aperiodic SRS subframe signal indicating whether or not to transmit a signal of uplink data in a specific time symbol. Meanwhile, the mobile station device 3 receives the uplink allocation signal, determines whether or not to map the uplink data to a specific time symbol according to the aperiodic SRS subframe signal, and transmits the uplink data to the base station device 1.
