高速下行分组接入系统中的快速小区选择技术

Fast Cell Selection Technology in Hi gh Speed Downlink Packet Access

高速下行分组接入(HSDPA)是WCDMA发展的第一步,采用了快速链路自适应(AMC)、快速混合重传(HARQ)及快速小区选择(FCS)等新技术。主要讨论高速下行分组接入(HSDPA)中快速小区选择(FCS)技术的应用背景、技术细节和性能评估,其中详细论述了Inter-NodeBFCS实现时需考虑的队列管理问题。最后,探讨了FCS技术中可以进一步研究的问题。

HSDPAis the first step of evolving WC DMA.Some new technologies such as fa st link adap-tation,fast hybrid ARQ and fast cell selection are adopted in HSDPA.In th is article,the application back-ground,technical details and perfo rmance of fast cell selection technology in HSDPA are discussed.The issue of queue management which need to be considered in the implementati on of Inter -NodeB FCS is de-scribed at length.Finally,some thesises of FCS to be further researched are brought forward
