| 摘 要： | 就TD—SCDMA系统而言，HSPA技术有两种增强型方式：一种为多载波捆绑技术，另一种为HSPA＋。其中HSPA＋包括分组业务持续连接（CPC）、增强CELL—FACH、层2增强、下行64QAM和MIMO等5种子技术。本文将对HSPA＋涉及的各项关键技术进行详细分析，并对引入各项技术后带来的性能增益进行评估。

| Abstract: | There are two key enhancement solutions for High Speed Package Access (HSPA) in TD-SCDMA system. One is multi-carrier for HSPA and the other one is HSPA+. For HSPA+,it includes Continuous Connective for Packet data (CPC),enhanced CELL_FACH,L2 enhancement,64 QAM and MIMO. This paper introduces and analyzes the key technologies in HSPA+,points out the possible improvements to the original system and evaluates the possible performance improvements. |
