Abstract:
    This method realizes power control on the up-going link of WCDMA system of using up-going boosting technique. It collects statistic of the error block ratio (EBT) on DPDCH. According to the aim value of EBT preset by the system, it calculates the signal interference ratio of renewed DPCCH, then according to the calculation result, regulates and controls the emitting power on DPCCH. The method collects statistic of real error block ratio and the number of re-transfer of MAC-d flow on E-DPDCH, calculates the power shift parameter of each MAC-d flow, then according to the calculation result, regulates the emitting power on each MAC-d flow. This power control method is applied on up-going link of WCDMA system of using up-going boosting technique. The invention regulates the emitting power of DPDCH and E-DPDCH periodically to ensure service quality and reduces interference inside the system.
