Abstract
A method for controlling power in a mobile network. The method includes, for each server station s, where s=1, . . . , A, belonging to a group of A server stations, where A≧2, each emitting with a power Ps(b), where b=1, . . . , B, in B sub-bands of frequencies, with B≧1, the following steps: a) receiving, from mobile terminals served by the server station s, measurements of radio parameters performed by these mobile terminals; b) calculating a predetermined value Vs,t(b), where bε[1, . . . , B] and tε[1, . . . , A], by using the measurements; c) transmitting to at least one other server station t, or an associate device, the respective value Vs,t(b), and reception, from at least the server station t or by the associated device, of the analogous value Vt,s(b); d) calculating, by using the value Vt,s(b), derivativeswhere U is a predetermined utility function for the network, and e) updating transmission powers Ps(b) to reduce the value of the utility function U.
