Abstract
A method for power control stabilization in the uplink of a cellular CDMA communication system applying a fast inner loop power control comprises determining (210) of a radio frame based RoT value for a cell. A radio frame based SINR is determined (212) for individual UEs in the cell. The RoT value is compared (214) with a first threshold. Each frame based SINRs is compared (218) with a second threshold. The fast inner loop power control for a UE is broken (220) in dependence of the comparisons. The breaking comprises commanding (222) of a first number of consecutive power down commands to UEs having the frame based SINR above the second threshold for a RoT value above the first threshold and toggling (224) of power control commands for the subset of UEs during a second number of radio frames for a RoT value above the first threshold.
