Patent ID: 6975879

Claim:
A method of controlling the transmission power in a cellular radio system comprising terminals, base stations, and radio network controllers, and where transmission power control comprises an outer loop control, wherein a radio network controller provides a base station with transmission power controlling information, and a closed-loop control, wherein a base station and a terminal control the transmission power according to said controlling information, and which cellular radio system further comprises a load control, wherein a radio network controller monitors and balances the use of radio resources in the base stations that operate under it, characterized in that to control the transmission power in a macrodiversity connection where a given branch goes between the serving radio network controller and the terminal through the drift radio network controller and the drift base station, it comprises the steps of: transmitting information limiting the transmission power in said macrodiversity connection branch from the drift radio network controller to the serving radio network controller, transmitting the information controlling the transmission power of said macrodiversity connection branch from the serving radio network controller to the drift radio network controller, and transmitting information controlling the transmission power of said macrodiversity connection branch from the drift radio network controller to the drift base station.
