Abstract:
1. A transmission power control method of controlling transmission power of an uplink signal at a mobile station setting a radio link with a first cell under the control of a first radio base station and with a second cell under the control of a second radio base station, the method comprising the steps of: (A) transferring, from the second radio base station to the first radio base station, a second uplink signal received from the mobile station in the second cell; (B) synthesizing, at the first radio base station, a first uplink signal received from the mobile station in the first cell with the second uplink signal transferred from the second radio base station, generating and transmitting a transmission power control signal for controlling the transmission power of the uplink signal at the mobile station based on a reception quality of an uplink signal obtained by synthesizing the first uplink signal with the second uplink signal; and (C) controlling, at the mobile station, the transmission power of the uplink signal based on the received transmission power control signal.
