RADIO FREQUENCY SHARING METHOD, RADIO BASE STATION CONTROL METHOD AND RADIO TERMINAL STATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio frequency sharing method capable of suppressing lowering of throughput by packet collision when a plurality of base stations and radio terminal stations share the same frequency. SOLUTION: In the radio frequency sharing method to perform access control of CSMA/CA in the case of data transmission by the radio base stations and the radio terminal stations, transmission cycles and timing of beacon are determined as the same among a plurality of base stations, a channel is confirmed to be idol after beacon transmission timing, transmission waiting time is determined by random numbers, a beacon signal is transmitted after confirming that a communication channel is at an idol state, communication in a cell of the present station is permitted to the next beacon transmission timing and when other beacon is detected during transmission standby time, transmission of the beacon is interrupted and service is interrupted till the next beacon transmission timing in the respective base stations.
