Abstract: A method for changing a downlink transmission power level can include receiving information about interference noise. When the interference noise satisfied a predefined level, the downlink transmission power level can be changed. Typically, the transmission power level can be decreased when the interference noise is above a predefined value. The transmission power level change can be coordinated (e.g. coordination in terms of power step size, in terms of frequency portion to which the power change is applied and in terms of time when to apply the transmission power change) with transmission power level changes in other cells. Also, interferences levels may be reassessed following the first transmission power change and the power levels are changes a second time. Optionally, only a portion of the transmission bandwidth is changed or only specific DL physical channels are considered.
