BASE STATION DEVICE

摘要

A base station communicating with mobile stations by using a frequency band within a transmission band based on orthogonal frequency division multiplexing is disclosed. The base station includes a multiplexing unit configured to multiplex a synchronization channel, for a mobile station performing an initial cell search, in a second frequency band including a center frequency on a raster of a first frequency band and having a bandwidth corresponding to the smallest one of receivable bandwidths of the mobile stations in a system. The multiplexing unit is configured to multiplex multiple synchronization channels, for a mobile station performing a neighboring cell search, in a third frequency band including the center frequency on the raster of the first frequency band and having a bandwidth that is greater than that of the second frequency band.
