Power control method for a GERAN system to increase GERAN network capacity

摘要

The present patent application comprises means, instructions and steps for controlling signal power by allowing a small bit error rate during burst processing comprising setting a transmit signal power granularity to be less than a current level (1210), tracking a power measurement report of at least one remote stations (1220), determining if at least one signal quality indicator has reached an upper threshold (1230), decreasing a downlink signal power if the at least one signal quality indicator reaches an upper threshold (1240), and stopping the decreasing of the downlink signal power (1260) when the at least one quality indicator reaches a lower threshold (1250).

1. A method for controlling GSM/EDGE Radio Access Network (GERAN) power operable at a base station, comprising:
setting a transmit signal power granularity to be less than a current level; tracking a power measurement report of at least one remote station, the power measurement report comprising at least one signal quality indicator representing a bit error rate on a burst processing level, wherein the at least one remote station comprises a downlink advanced receiver performance (DARP) remote station and a non-DARP remote station; determining if the at least one signal quality indicator has reached a first threshold; decreasing a downlink signal power if said at least one signal quality indicator reaches the first threshold; and stopping said decreasing of said downlink signal power when said at least one signal quality indicator reaches a second threshold lower than the first threshold, wherein the bit error rate corresponding to the second threshold is higher than that of the first threshold.
