Abstract

The invention relates to a method for uplink transmission interference limitation in a wireless communications system comprising a mobile network arranged in a radio cell configuration, each cell comprising a serving base station providing communications service to at least one user terminal inside the cell area, the method comprising the steps of selecting and forcing a first group of cell-associated terminals to stop transmission for a certain period of time selecting a second group of terminals for measuring the signal power present at their uplink transmission frequency; calculating an indication of the interference level generated by at least the second group of selected terminals in at least one neighboring cell; selecting a third group of cell-associated terminals and setting their uplink transmission power to a certain value according to the calculated interference level.
