Abstract:
1. A wireless communication base station apparatus comprising: a measuring section that measures a reception level of a downlink common pilot signal; a determination section that determines whether the received downlink common pilot signal is a signal transmitted from a macro base station or a signal transmitted from a peripheral femto base station; and a power control section that executes a first power control to control total downlink transmission power in a first power control range according to the reception level of the downlink common pilot signal transmitted from the macro base station when the downlink common pilot signal is determined to be the signal transmitted from the macro base station, and that executes the first power control and a second power control to control the total downlink transmission power in a second power control range set smaller than the first power control range according to a result of the first power control and the reception level of the downlink common pilot signal transmitted from the femto base station when the measured downlink common pilot signal is determined to be the signal transmitted from the femto base station.
