PROBLEM TO BE SOLVED: To provide a method and a device for transmitting/receiving radio data communication with which high throughput characteristics can be provided, the random access of a radio channel is enabled and a radio data communication system capable of dealing with increase/decrease in the number of radio terminals can be provided as well. SOLUTION: Between radio base station equipment 1 and radio terminal station equipment 2, high-speed data signals to be transmitted at high speed for large capacitance are transmitted by outgoing and incoming non-SS signals 6 and 7, the low speed signals of small capacitance such as radio channel control signals are transmitted by outgoing and incoming SS signals 5 and 8 and these signals are separated. Besides, while using a radio signal modulating system not to mutually interfere both these signals, the signals in the same direction are transmitted at the same time by the same frequency band and TDD transmission is performed. Further, while using a code multiplex system as a radio signal modulating system for transmitting the radio channel control signals, the respective radio channel control signals are transmitted while being multiplexed. |
