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

ACH、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

ACH

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.
