BASE STATION DEVICE, MOBILE STATION, RADIO COMMUNICATION SYSTEM, SYNCHRONIZATION SIGNAL TRANSMISSION METHOD, AND SYNCHRONIZATION SIGNAL RECEPTION METHOD

摘要

A radio communication system includes a plurality of mobile stations and a plurality of base station devices which perform communication with the mobile stations by using the OFDM method. The radio communication system includes sequence definition means which defines a sequence of first synchronization signals and a transmission patter of first synchronization signals and second synchronization signals. According to a cell ID or a cell ID group, the transmission timings of a P-SCH sequence and P-SCH and S-SCH are decided by a synchronization signal control unit 2091.
