Claim:
1. A mobile station comprising: a Fourier transform unit configured to Fourier transform a first control signal; a mapping unit configured to map the Fourier transformed first control signal such that the first control signal and a second control signal are multiplexed within a first transmission bandwidth, the second control signal being transmitted by another mobile station to a base station; an inverse Fourier transform unit configured to inverse Fourier transform the mapped first control signal; a transmitter configured to transmit the inverse Fourier transformed first control signal to the base station in a first transmission interval; and a reference signal generation unit configured to generate a first reference signal sequence having a sequence length corresponding to an amount of all subcarriers included in the first transmission bandwidth; wherein the mapping unit maps the generated first reference signal sequence such that the first reference signal sequence is code multiplexed with a second reference signal sequence, which is transmitted by the other mobile station to the base station, within the first transmission bandwidth, the second reference signal sequence having the same sequence length as the first reference signal sequence, the inverse Fourier transform unit is configured to inverse Fourier transform the mapped first reference signal, and the transmitter transmits the inverse Fourier transformed first reference signal to the base station in a second transmission interval.
