Abstract:
1. A method for power control stabilization in the uplink of a cellular Code Division Multiple Access (CDMA) communication system applying a fast inner loop power control, said method comprises the steps of: determining a radio frame based rise over thermal (RoT) value for a cell in said cellular communication system; determining a radio frame based signal to interference and noise ratio (SINR) for each User Equipment (UE) in a subset of UEs being present in said cell; comparing said RoT value with a first threshold; comparing said frame based SINRs with a second threshold for each of said UEs in said subset; breaking said fast inner loop power control for a UE in dependence of a result of said step of comparing said RoT value with a first threshold and a result of said step of comparing said frame based SINRs with a second threshold; said step of breaking said fast inner loop power control in turn comprising: commanding a first number of consecutive power down commands to UEs having said frame based SINR above said second threshold as response to a RoT value above said first threshold; and toggling power control commands for said subset of UEs during a second number of radio frames as response to a RoT value above said first threshold.
