Abstract  Abstract

In a CDMA mobile communication system for realizing a multiple-access a common reverse channel 10 is divided into an access channel 10A and a message channel 10B. When data (packet) to be transmitted occurs in any mobile station 1-4 mobile station having data to be transmitted transmits a transmission request signal including information such as packet size or the like by using the access channel 10A. In contrast base station 30 transmits a transmission permission signal which designates a transmission timing of data and a spreading code to be used as transmitting on the basis of the state of utilization of message channel 10B and the state of occurrence of data. Mobile stations 1-4 transmits data in accordance with the spreading code and the transmission timing which are designated from base station 30.
