摘要：

为了提高 TD-SCDMA 系统的传输速率，向国际电联 IMT-Advanced 所提技术指标迈进， TD-SCDMA的演进策略提上了研究议程。鉴于TD-SCDMA的短期演进HSPA（包括HSDPA和HSUPA）无法满足 IMT-Advanced 的要求，提出了 HSPA＋和 LTE 的概念。本文首先介绍了TD-SCDMA 未来演进和发展的趋势，包括TD-SCDMA 的增强、短期演进、中长期演进以及基于IMT-Advanced的4G等。然后重点分析了HSPA＋的关键技术和协议架构等，最后对LTE的帧结构和多址方式进行了分析，提出了演进时的关键点和对策。

Abstract:

In order to improve the transmission rate of TD-SCDMA and approach the technology performance requirements ofIMT-Advanced proposed by ITU, the evolution strategies of TD-SCDMA are urgent. Considering the short term evolutiontechnologies (named as HSPA, including HSDPA and HSUPA) not satisfying with requirements of IMT-Advanced, the HSPA＋ andLTE technologies are proposed. This paper introduced the general evolution strategies of TD-SCDMA, and discussed theenhancement, short term evolution, medium and long term evolution, IMT-advanced based 4G technologies firstly. Then the keytechniques and protocol structure of HSPA＋ are focused, following by the frame structure and multiple access techniques of LTE.The key points and solutions for TD-SCDMA evolution are presented finally.

Key words: KTD-SCDMA, HSPA, HSPA＋, LTE, IMT-Advanced
