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 () of a radio frame based RoT value for a cell. A radio frame based SINR is determined () for individual UEs in the cell. The RoT value is compared () with a first threshold. Each frame based SINRs is compared () with a second threshold. The fast inner loop power control for a UE is broken () in dependence of the comparisons. The breaking comprises commanding () 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 () of power control commands for the subset of UEs during a second number of radio frames for a RoT value above the first threshold.
