Abstract: To provide appropriate communication quality between a radio station (e.g., small-scale base station) and a mobile station in a state where the radio station is located within a large-scale cell and communicates with the mobile station while reducing interference exerted on the large-scale cell by communication between the radio station and the mobile station regardless of the place of the radio station within the large-scale cell. A femto base station 4 sets a target received power RTWP_target of uplink data used for controlling transmission power of uplink data transmission from a mobile station on an uplink based on a measurement result of received power Pmacro of a pilot signal transmitted from a macro base station 3. Specifically, the target received power RTWP_target is preferably set to a larger value as the received power Pmacro of the pilot signal becomes smaller.

Abstract: A base station 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. 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 first downlink communication when using the entire range of the radio resource region that is shared with the other base station. The detection unit detects execution of resource division by the other base station for limiting radio resources used for another downlink communication between the other base station and a mobile station to a second radio resource segment.

A femto base station 1 performs radio communication with mobile stations 6-1 and 6-2. The femto base station 1 includes a radio resource control unit 15. The radio resource control unit 15 obtains a measured value of a reception quality level that is obtained by the femto base station 1 and the mobile stations 6-1 and 6-2 by measuring the reception quality level of an external radio signal S1. Further, the radio resource control unit 15 determines a radio parameter relating to radio communication between the femto base station 1 and the mobile stations 6-1 and 6-2 based on a relative comparison between a plurality of reception quality levels. The external radio signal S1 is a radio signal transmitted from an external radio station 9 that is different from any of the femto base station 1 and the mobile stations 6-1 and 6-2.
