摘　　要：高速上行分组接入(HSUPA)是3GPP标准化组织为进一步满足数据业务需求在TD-SCDMA UTRA-TDD R6版本中提出的一种新技术,描述了引入HSUPA后TD-SCDMA系统的演化,阐述了HSUPA中涉及的物理层混合自动请求重传(HARQ)、快速调度、自适应调制与编码等关键技术及其相应研究,最后讨论了HSUPA技术应用于TD-SCDMA的发展前景。High Speed Uplink Packet Access （HSUPA） is a UMTS / WCDMA uplink evolution technology currently being standardized in 3rd Generation Partnership Project （3GPP） ; HSUPA is expected to be standardized by the 3GPP in UMTS Release 6. This article elaborates the changes of TD-SCDMA system after using HSUPA, and the physical layer＇s new technology of HSUPA such as HARQ, fast Node-B Rate Scheduling, and AMC. In the last it describes the future prospects of TD-SCDMA if the new technology were in use.
