摘要 本文介绍了WCDMA增强型无线技术——HSUPA(高速上行分组接入)技术,并详细讨论了其核心技术:AMC(自适应调制和编码)技术、HARQ(混合自动传输请求)技术以及快速调度和软切换技术。文中还将先前流行的HSDPA(高速下行分组接入)技术和HSUPA的软切换技术作了简单地比较。 An enhanced technology of WCDMA high speed uplink packet access(HSUPA) are introduced in this paper,and the core technology of HSUPA:AMC,HARQ,Fast scheduling and Soft switch are focused.The comparison of the technology of High Speed downlink packages access(HSDPA) which is popular early with HSUPA is made.
