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。
There are two key enhancement solutions for High Speed Package Access （HSPA） in TD-SCI）MA 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.
