<P>PROBLEM TO BE SOLVED: To provide a radio communication system avoiding interference between base station groups by controlling a use frequency and transmission power by a base station with coordination of groups of moving terminal stations or base stations. <P>SOLUTION: In the radio communication system, a base station 21 makes synchronized terminal stations 11 as a base station group 1, receives information on a radio wave situation from the terminal stations 11, performs carrier sensing based on information of the radio wave situation, transmits/receives information on positions of the base stations and radio terminal stations in the respective groups, information on movement and information on communication as coordination information among the base stations of each group to share it when occurrence of the interference is detected with the other approaching base station group 2, performs an operation processing of interference avoidance based on the coordination information and controls the interference avoidance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
