PROBLEM TO BE SOLVED: To improve reception quality of transmission data in a mobile station by preventing interference between a sequence used for synchronization and the transmission data.SOLUTION: In a base station device 100, a frame forming section 120 forms a frame by arranging transmission data and the sequences for identifying a frame timing and a code group to which base station scrambling codes belong at a receiving side so as not to overlap with each other using the same symbol which is specified by a sub-carrier and time, and then an RF transmission section 150 transmits the frame. In a mobile station device 200, an RF receiving section 210 receives the frame from the base station device 100, and an SCH correlation value calculating section 240 multiplies the frame by all the candidates of the sequence one by one to take correlation, and a frame timing/code group detecting section 250 detects the frame timing and the code group based on the correlation value obtained from the SCH correlation value calculating section 240. |
