PROBLEM TO BE SOLVED: To permit the deviation amount of a frame timings in respective base stations and a reference station to be within a permission range by executing a frame synchronization processing based on the deviation amount of the frame timings between a self station and a reference station and also adding the deviation amount of the frame timings of the both stations to a control signal so as to transmit it. SOLUTION: The number of deviation bits between the frame timing of the self station and that of the reference station is calculated based on the control signal outputted from the reference station (S3). Then, it is discriminated whether or not the deviation bit number exceeds the number of permission bits (S4). When the deviation bit number exceeds the permission bit number, the frame timing of the self station is permitted to coincide with that of the reference station and, after that, the number of the deviation bits between the self station and the reference station is added to the control signal so as to be transmitted (S5 and S6). In the meantime, unless the deviation bit number exceeds the permission bit number, the calculated number of the deviation bits in the frame timings between the self station and the reference station is added to the control signal so as to be transmitted (6).
