RADIO COMMUNICATION SYSTEM, BASE STATION APPARATUS, RADIO RESOURCE CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

A base station (1-1) includes a radio communication unit, a resource adjustment unit, a resource division unit and a detection unit. The resource adjustment unit determines radio resources to be allocated to a downlink communication from a radio resource region shared with another base station (1-2). The resource division unit limits, 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 downlink communication using the limited first radio resource segment is improved over the communication quality of the downlink communication when using the entire range of the radio resource region. The detection unit detects execution of resource division by the other base station (1-2) for limiting radio resources used for another downlink communication between the other base station (1-2) and a mobile station (2-2) to a second radio resource segment.
