摘　　要：围绕如何改善目前HSDPA数据业务低速率的问题,以解决日益增长的数据传输速率需求与网络负荷间的矛盾。研究分析了无线环境、无线资源、传输带宽、高速共享控制信道受限以及MAC-hs重传等影响HSDPA速率的各种因素,从根本上解决现网HSDPA低速率的能力瓶颈,实现灵活高效的数据传输,为WCDMA网络优化提供参考。It focuses on improving the issues on HSDPA data service low rate to solve the contradiction of increasing data transmission rate demand and network load. It analyzes the factors which effect HSDPA rate,including wireless environment,wireless resource,transmission bandwidth,limited channel of high-speed shared control and MAC-hs retransmission. It is essential to solve the current low rate of capacity bottleneck in HSDPA network,and perform a flexible and reliable data transmission to provide reference for WCDMA network optimization.
