摘要： To effectively suppress interference on other radio stations located in the vicinity, when the radio station performs radio communication with a registered radio station. A femto base station 1 stores a history of connection requests issued by an unregistered radio station that is not pre-registered in the femto base station 1. Then, the femto base station 1 determines the need of a adjustment of a radio resource used in communication with a registered radio station that is pre-registered in the femto base station 1 itself by using connection request frequencies each for one of unregistered radio stations obtained from the connection request history as an index.

摘要： 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.

摘要： To provide appropriate communication quality inside a building regardless of the building penetration loss of the building in which a femto base station is installed while suppressing the interference caused by radio waves leaked outside the building, a femto base station 4 receives a radio signal that passes through a structure and arrives at the installation place of the femto base station 4 (e.g., radio signal transmitted from a Global Positioning System) and estimates the penetration loss L of the structure based on the receiving state of the radio signal. Further, the femto base station 4 performs radio resource management based on an estimation result of the penetration loss L, and communicates with a mobile station 7-2.

摘要： To provide appropriate communication quality for a mobile station that is permitted to connect to a femto base station regardless of the place at which the femto base station is installed and the place at which the mobile station is used while reducing the transmission power of the femto base station as much as possible, a femto base station 4 measures the reception quality (e.g., received power or reception SIR) by receiving a common pilot signal from a macro base station 3, and sets the transmission power Ptx of a pilot signal to be transmitted by the femto base station itself based on the received power. Further, the femto base station 4 transmits a common pilot signal with a transmission power Ptx and communicates with a plurality of mobile stations 7-2 to 7-4 within a femtocell 6. Furthermore, the femto base station 4 receives a measurement result of the reception quality level of a common pilot signal transmitted from the femto base station 4 from the mobile stations 7-2 to 7-4, and adjusts the transmission power Ptx of a common pilot signal so that the lowest level among a plurality of reception quality levels gets closer to a predetermined target level.
