MOBILE COMMUNICATION SYSTEM, TRANSMITTING DEVICE, RECEIVING DEVICE, AND METHOD

摘要

A transmitter in a multi-carrier type mobile communication system has a mapping means that maps control information for a sub-carrier in a certain sub-frame, a means that performs an inverse Fourier transform of signals after mapping, and a means that wirelessly transmits transmission signals, which include the signals after the inverse Fourier transform, to a receiver. The control information is mapped in a plurality of bands that are prepared discontinuously in a frequency region over the period of the sub-frame and that are prepared separately from the band for the common data channel. Mapping is performed such that the control information for a receiver address mapped to a certain of the plurality of bands, and the control information or the common data channel for a receiver address mapped at another frequency are transmitted at the same time.
