Abstract
A method of adjusting downlink transmission power at a base station based on the measured SIR relative to a referenced level in a mobile terminal. The referenced level can be the targeted SIR or zero. When the measured SIR is greater than the referenced level, the measured SIR is further compared to a first threshold value in order to determine the step size for power reduction. When the measured SIR is smaller than the referenced level, the measured SIR is further compared to a second threshold value in order to determine the step size for power increase. The first and second threshold values can be derived from the target SIR and TPC step size as provided in the RRC signal. Furthermore, the step values and threshold can be based on statistical analysis while the system is running.
