Base station, mobile station and method |
摘要 |
A base station performs communication of an orthogonal frequency division multiplexing (OFDM) scheme with a mobile station by using any one of equal to or greater than two frequency bands. The base station includes means that transmits a synchronization channel and a control channel using a band that includes a center frequency fA on a raster of a first band (20 MHz) and that has a bandwidth equal to or greater than that of a second band (5 MHz of the end). The control channel includes center frequency information for specifying a center frequency fA′ of the second band. Since the mobile station moves to a desired band after obtaining center frequency information using a band including the center frequency on a raster, the mobile station can connect to the desired band without searching frequencies that are not on the raster.
