POWER CONTROL METHOD FOR A REVERSE DATA SERVICE

摘要

An external circuit power control method for a reverse data service is provided. The system efficiency can be improved in a reverse data service at 144Kbps by adopting an optimized reverse channel external circuit power control algorithm. The power control method of the present invention applies a new outer loop external circuit power control algorithm in order to improve performance of the reverse data service at 144Kpbs. The algorithm determines a Target Eb/Nt according to the frame state of a supplemental channel through which data is transmitted. That is, the power control method of the present invention applies the frame state of the data inputted to the supplemental channel as an important value in determining power control, whreas in the conventional algorithm, a voice rate and frame state received through a reverse fundamental channel are considered in determining power control. Therefore, the present invention can reduce the complexity of the conventional algorithm and perform the outer loop power control correctly according to the state of real input data.
