Abstract
A method of controlling transmission power in a mobile radiocommunications system, in which at least two distinct physical channels transmitted by a single transmitter have their respective transmission powers controlled by a power control algorithm as a function of a target value for transmission quality (SIR target) correspond to a first channel which is taken as a reference, and in which, for a second channel, a transmission power offset (PO) relative to the first channel is applied, where necessary, the method being essentially characterized in that when there is a change in the required transmission conditions, a variation having a first value (Δ1) is applied to said target value (SIR target), and a variation having a second value (Δ2) is applied to said power offset (PO) so that said first channel has its transmission power changed by said first value and the second channel has its transmission power changed by a value equal to the difference (Δ1−Δ2) between said first and second values.
