description PROBLEM TO BE SOLVED: To provide a radio communication system improving the throughput of the entire system. SOLUTION: In the radio communication system, any one of a plurality of terminal devices is allocated to each of a plurality of orthogonal frequencies on the basis of channel gain information indicating channel gain between the plurality of terminal devices and a plurality of antennas, and for each of the plurality of terminal devices, transmission signals for which the signals of a frequency domain obtained by executing discrete Fourier transformation, for which the number of the orthogonal frequencies allocated to the terminal device is points, to a data sequence transmitted or received by the terminal device are arranged to the orthogonal frequencies allocated to the terminal device are transmitted by a single carrier. Also, in the received transmission signals, for each of the plurality of terminal devices, the signals arranged to the orthogonal frequencies allocated to the terminal device are selected from the transmission signals, inverse discrete Fourier transformation, for which the number of the orthogonal frequencies allocated to the terminal device is points, is executed to the selected signals, and the data sequence is obtained.
