摘要
为了满足移动网络中高速数据业务的需求,TD-SCDMA在Release 7中引入了高速上行分组接入(HSUPA)技术。现介绍了TD-HSUPA的原理,阐述了TD-HSUPA的关键技术及其实现,主要比较了在TD-SCDMA和WCDMA两种系统中HSUPA技术应用的差异并分析了原因。对TD-SCDMA下一步演进技术HSPA+和LET等的发展有着重要的指导意义和参考价值。
TD-SCDMA introduces the high-speed uplink packet access （HSUPA） in Release 7 to satisfy the demand of service for high-speed data service in the mobile network. This paper briefly introduces the principle of TD-HSUPA, elaborates the essential technology of TD-HSUPA and its implementation, compares the difference of the HSUPA technology application in TD-SCDMA system with that in WCDMA system. It is significant to the next step of TD-SCDMA evaluation technology （HSPA ＋ LET）.
