Abstract:
1. In a system for controlling the transmission power of a base station configured to communicate with a plurality of mobile stations, said base station comprising: a plurality of power command units each configured to receive a signal intended for one of said plurality of mobile stations and a power command signal sent by one of said plurality of mobile stations; a plurality of summation units each configured to form a sub-composite signal from a group of input signals having a given priority level transmitted by the plurality of power command units; a plurality of attenuation units each configured to attenuate the sub-composite signal transmitted by respective one of the plurality of summation units by applying respective attenuation coefficients; and a summer configured to form a composite signal to be transmitted to said plurality of mobile stations from signals transmitted by the plurality of attenuation units, wherein the attenuation coefficient of each of the plurality of attenuation units is a power P of a base attenuation coefficient, the value of P being identical for all said attenuation units, and wherein the value of the attenuation coefficient of each of the plurality of attenuation units is less than one, the value of the attenuation coefficient of each of the plurality of attenuation units being closer to one for sub-composite signals having high priority level.
