摘要
HSDPA引入了一种全新的信道类型(高速下行链路共享信道),这种信道能够有效利用无线频率资源,并充分考虑到猝发分组数据的传输需求。本文分析了HSDPA3个演进阶段(基本HSDPA阶段、增强HSDPA阶段与HSDPA进一步演进阶段)的关键技术,并对HSDPA的使用过程进行了研究。
HSDPA introduces a new transport channel type, high-speed downlink shared channel, which makes efficient use of valuableradio frequency resources and takes into account bursty packet data. This paper analyzes the critical techniques in three development phases of HSDPA, i.e. basic HSDPA phase, enhanced HSDPA phase and HSDPA further development phase. Finally, we study on the usage of HSDPA.
