CONTROLLING UPLINK POWER LEVEL OF RADIO CELLS

A method of controlling uplink power levels of radio cells in a wireless communications network is disclosed. The method comprises grouping sets of neighboring cells into a plurality of cell clusters, identifying at least one first cell cluster comprising at least one cell being subjected to interference and having a signal quality exceeding a signal quality threshold value, identifying at least one second cell cluster comprising at least one cell being subjected to interference and having a signal quality below the signal quality threshold value; creating a model based on the identified first cell cluster to map a nominal uplink power level to an estimated signal quality value thereof, and adjusting a nominal uplink power level of the at least one cell of the second cell cluster by applying the nominal uplink power level derived from the created model to attain a corresponding estimated signal quality value therein.
