【摘要】 高速下行分组接入(HSDPA, High Speed Downlink Packages Access)是WCDMA规范R5版本中的关键新特征,通过AMC和HARQ技术在减少延迟的基础上增加数据传输的吞吐量和峰值数据率,为多用户提供高速下行数据服务,特别适合移动多媒体、Internet等大量下载信息的业务。HSDPA技术可使空中接口下行速率达到10Mbps以上,是一项很有前途的新技术。本文首先简单介绍HSDPA系统,研究MAC-hs的特点、HSDPA新增的信道和引入的关键技术；接着分析HSDPA调度子系统的功能,研究MAC-hs分组调度器和流量控制器的设计和不同算法比较；最后研究HSDPA调度子系统的详细实现,包括子系统的功能、框架、相关的原理、数据、状态机、重要函数的实现和测试结果。更多还原

【Abstract】 High Speed Downlink Packet Access (HSDPA) is a key feature of the R5 version of the WCDMA specification. By using AMC and HARQ technology, the delay can be reduced, and the data transfer rate and peak data rate can be increased. It provides users with high-speed downlink data services, especially for mobile multimedia and internet download. HSDPA technology will enable the air interface rate reach to 10Mbps, and it is a highly promising market of new technology.Firstly, HSDPA system is introduced including the characteristic of MAC-hs, HSDPA new channels and key technologies. Then, HSDPA scheduler sub-system function, including the framework and algorithms of MAC-hs scheduler and flow volume controller, are discussed. Finally, the design and implementation detail of the HSDPA scheduler sub-system, including the function, framework, design of data, state machine, implementation of important functions and test result, are given.更多还原
