Abstract:
1. A radio communication system comprising: a first base station configured to perform radio communication including at least a first downlink communication with a first mobile station; a second base station configured to perform radio communication including at least a second downlink communication with a second mobile station; a first resource adjustment unit configured to determine radio resources to be allocated to the first downlink communication from a radio resource region shared between the first and second base stations; a quality estimation unit configured to estimate communication quality of the first downlink communication when radio resources allocatable to the first downlink communication are limited to a part of the radio resource region; a first resource division unit configured to limit, to a first radio resource segment which is a part of the radio resource region, radio resources in response to estimating that communication quality of the first downlink communication using the limited first radio resource segment is improved over the communication quality of the first downlink communication when using the entire range of the radio resource region that is shared with the second base station; a second resource adjustment unit configured to determine radio resources to be allocated to the second downlink communication from the radio resource region; a detection unit configured to detect execution of resource division for limiting radio resources used for the first downlink communication to the first radio resource segment; and a second resource division unit configured to limit, to a second radio resource segment which is a part of the radio resource region and different from the first radio resource segment, radio resources allocatable to the second downlink communication by the second resource adjustment unit in response to detection of the resource division.
