A method of coordinating a transmitter with K&#x2212;1 transmitters of a group of K transmitters. The K transmitters are in communication respectively with K receivers via channels that are described, for a frequency band m by direct transmission channel gains (g) when j=i and by interfering transmission channel gains (g) when j&#x2260;i between the transmitter j and the receiver i, i&#x2208;{1, . . . , K}, j&#x2208;{1, . . . , K}, K&#x3e;1. Each transmitter has available an estimate of the direct channel gain and estimates of the gains of channels interfering with its receiver. The method includes an 'exchange' stage during which the K transmitters transmit simultaneously K respective sequences of subframes of respective power levels per band m coding the estimated channel gains (&#x11d;) and during which the K transmitters receive, after each subframe, signal to interference plus noise ratios as returned by the K receivers to their respective transmitters.
