PROBLEM TO BE SOLVED: To enable simultaneous transmission by a plurality of transmitting stations through positive utilization of capture effects, etc., while coexisting with a conventional CSMA/CA system.SOLUTION: There is provided a radio access control method in a radio communication system in which a plurality of communication cells composed of transmitting and receiving stations are disposed overlapping each other. The radio access control method includes: a step in which each of the receiving stations measure desired signal power from a transmitting station performing communication with the receiving station concerned and interference signal power from transmitting stations other than the transmitting station, respectively, and notify the transmitting station of a ratio of the desired signal power to the interference signal power; a step in which, when the ratio of the desired signal power to the interference signal power notified by the receiving station exceeds a threshold, the transmitting stations share a fixed back-off value with the transmitting stations transmitting the interference signal; and a step in which the transmitting stations sharing the fixed back-off value transmit a radio signal addressed to their respective subordinate receiving stations when they find by carrier sense that the fixed back-off value has decremented to 0. |
