PROBLEM TO BE SOLVED: To improve the influence of selective fading and to also realize fast data transmission in a radio data communication system which uses networks. SOLUTION: A transmission signal 10 from a base station 4 is modulated with a DS/SS, using a base station identification number. Mobile stations 1 and 2 (5-1 and 5-2) retrieve the base station identification number from the signal 10 and obtain transmission data to a self-station through back-diffusion by using the number. Transmission data is subjected to packet multiplexing by IPMA method, in an illustrated example, the mobile station obtains the packet of an MS1 from the signal 10, and the mobile station 5-2 obtains the packet of an MS2. The respective mobile stations perform DS/SS modulation of the signal, by using the base station identification number of the base station, where the respective mobile stations are registered and transmit the packet of the MS1 or the MS2.
