A base station uses one of two or more frequency bands to perform communication of OFDM scheme with a mobile station. The base station has a means that transmits a synchronization channel and a control channel by use of a band which includes the center frequency (f<sub>A</sub>), on the raster, of a first band (20 MHz) and the bandwidth of which is wider than the bandwidth of a second band (5 MHz at an end). The control channel includes center frequency information that determines the center frequency (f<sub>??</sub>) of the second band. After acquiring the center frequency information in the band including the center frequency on the raster, the mobile station shifts to a desired band. Thus, the mobile station can be connected to the desired band without searching for any frequencies that are not existent on the raster.
