-SCDMA中上行增强技术混合TTI的研究
iscussion of New High Speed Uplink Packet Access Technology in TD-SCDMA
-SCDMA第三代移动通信系统标准，是我国提出并得到国际电信联盟（ITU）批准的主流标准，也是3GPP的重要组成部分。随着无线数据业务的增加，服务质量要求的提高，系统本身必须具有适合传输高速率数据业务的特性，3GPP R5、R6版本规范中分别引入了高速下行和上行分组业务，即HSDPA和HSUPA。本文对TD-SCDMA系统中HSUPA的技术进行了探讨，提出了混合TTI方案，并通过计算机仿真对其方案性能进行了分析与研究。
-SCDMA is proposed by China, approved as one of 3G standards by ITU, and joined 3GPP in March 2001.The system must have capability that supports high speed packet data services with better quality. Therefore, HSDPA and HSUPA are proposed by 3GPP R5 and R6 for further improvement of packet data service. This paper discusses high speed uplink packet access technology in particular. The evolution of new enhancing technology is described and is in the paper. Performance of the proposed scheme is also demonstrated using a system level simulation.
