Abstract A code division multiple access mobile communication system which is composed of a plurality of base station and at least a mobile station communicates through the scheme of code division multiple access by radio channel. In the code division multiple access mobile communication system, each base station and at least a station control a transmission frame sent by at least a radio channel so as not to transmit the frame of the data not sent; the offsets with respect to the transmission timings are assigned to the respective channels at random and transmitted; and transmitting respective transmission frame through respective channel when having the offsets to the transmission timings assigned by the distribution step.
