Patent ID: 8538342

Claim:
A radio station apparatus that performs radio communication with at least one opposed radio station, comprising: an external radio signal reception unit configured to measure a reception quality level of an external radio signal transmitted from an external radio station that is different from any of the radio station apparatus and the at least one opposed radio station; radio resource control unit configured to obtain measured values of the reception quality level of the external radio signal that are measured by both the external radio signal reception unit and the at least one opposed radio station, and determining a radio parameter relating to radio communication between the radio station apparatus and the at least one opposed radio station based on a relative comparison between the measured values of the reception quality level, wherein when a first condition that the reception quality level measured by the external radio signal reception unit is smaller than a first reference value obtained from the reception quality levels measured by the at least one opposed radio station is satisfied, the radio resource control unit determines the radio parameter such that downlink transmission power from the radio station apparatus to the opposed radio station becomes relatively larger in comparison to when the first condition is not satisfied.
