Patent ID: 8010147

Claim:
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: the serving base station selecting and forcing a first group of cell-associated terminals to stop transmission for a certain period of time; the serving base station selecting a second group of terminals for measuring received signal power present at their uplink transmission frequency during the certain period of time; the serving base station directing the second group of terminals to measure the signal power received by the terminals of the second group at the uplink frequency of the terminals of the second group during the certain period of time; calculating an indication of the interference level generated by at least the second group of selected terminals in at least one neighbouring cell based on the received signal power measured by the terminals of the second group; selecting a third group of cell-associated terminals and setting their uplink transmission power to a certain value according to the calculated interference level.
