MULTICARRIER RADIO COMMUNICATION SYSTEM, BASE STATION, RADIO RELAY STATION, MOBILE STATION, AND MULTICARRIER RADIO COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To provide a multicarrier radio communication system with which suitable radio resources may be allocated to radio links to mobile stations. SOLUTION: The multicarrier radio communication system includes a first mobile station MSTlocated at a position where it is possible to directly communicate with a base station BS and also to communicate with a radio relay station RS, and a second mobile station MSNTlocated at a position where it is impossible to directly communicate with the base station but it is possible to communicate with the radio relay station. In order to allocate subcarriers to signals, the base station BS determines an order of priority for signals destined for mobile stations on the basis of whether each mobile station is the first mobile station MSTor not. The radio relay station RS allocates subcarriers to the signals, independently of subcarrier allocation made at the base station BS. In order to allocate subcarriers, the radio relay station RS determines an order of priority for signals on the basis of whether each mobile station is the first mobile station MSTor not.
