Abstract
A method for controlling transmission power of a radio transmitter in a cellular communications system, such as in a CDMA-system, which includes determining a reference value (SIR.sub.m) indicating the quality of the signals received from the radiotransmitter, determining a reference value (P.sub.m, SIR.sub.pm) indicating the current traffic load in the radiocell, and commanding the radio transmitter to adjust transmission power. In order to improve speed and reliability during any traffic conditions the method includes comparing both the reference value (SIR.sub.m) for the quality of the received signals, and the reference value (P.sub.m, SIR.sub.pm) for the traffic load with predetermined target values (SIR.sub.t, P.sub.t, SIR.sub.pt), and practicing the commanding of the radio transmitter to adjust its transmission power depending on the result of the comparison.
