The object of the present invention to provide a transmission power control method which controls a transmission power of a downlink common channel so that the transmission power is adapted to a radio state of each mobile station, and thereby makes it possible to prevent unnecessary power consumption, reduce interference to other mobile stations, and increase a downlink capacity. The transmission power control method includes (A) acquiring reception quality information of a downlink for a mobile station, (B) measuring a time difference between when an uplink signal is received from the mobile station and when a downlink signal to be transmitted to the mobile station occurs, (C) comparing the measured time difference with a predetermined threshold, and (D) setting a transmission power of a downlink common channel for mobile stations in accordance with the reception quality information, when the time difference is equal to or less than the predetermined threshold. |
