Abstract:
To secure proper reception quality for the control signal of an EUDCH during a handover. A transmission power control unit 23 controls transmission power of a downlink control signal of an EUDCH based on at least one of the following information: the CQI in an HS-DPCCH transmitted from a mobile station 30 regarding HSDPA to the mobile station 30, information on the reflection timing of a control pointer of the EUDCH from the mobile station 30, and information on transmission power of the HS-DSCH regarding HSDPA to the mobile station 30. A transmission unit 12 transmits the downlink control signal of the EUDCH to the mobile station 30 with a controlled transmission power.
