摘　　要：反向闭环功率控制是WCDMA系统中克服远近效应提高系统容量的核心技术之一．本文提出了一种基于动态步长的反向功率控制技术，采用这种方法能够加快移动台的发射功率调整，从而减少固定步长功率控制由于响应速度较慢引起的误帧和摔话，提高空中接口的传输性能．Reverse-link closed loop power control is one of the core technologies that can overcome near-far effect and improve system capacity. We propose a reverse link power control method based on dynamic step size. The speed for mobile transmitting power modification will be enhanced when the method is employed, and, as a result, the frame error and losing speech caused by slower response speed will be reduced with fixed step size power control and the transmission performance on the air interface improved.
