According to the present invention, in order to accurately demodulate a signal addressed to a terminal device and improve throughput, said terminal device, which communicates with a base station device, is provided with a signal detection unit that, when a prescribed transmission mode is set, demodulates the signal addressed to said terminal device on the basis of a first modulation mapping and, when a transmission mode other than said prescribed transmission mode is set, demodulates the signal on the basis of a second modulation mapping. A base station device that communicates with the terminal device is provided with a modulation unit that, when a prescribed transmission mode is set, carries out modulation from bits addressed to a plurality of terminal devices by means of the first modulation mapping and, when a transmission mode other than said prescribed transmission mode is set, carries out modulation from bits addressed to one terminal device by means of the second modulation mapping. |
