HSDPA关键技术及未来发展趋势分析
he Analysis of HSDPA Key Technologies and Prospect
作为把3G推向3.5G的关键技术HSDPA（高速下行分组接入）已经受到业界的广泛关注，在WCDMA 网络中引入HSDPA技术，可以提供更高的数据传输速率和更短的传输送时延。本文重点分析了HSDPA应用的几种关键技术，并通过简单的示意图说明了HSDPA技术的操作过程。针对目前没有商用的WCDMA网络，本文具体分析了理论上可供采用的在WCDMA网络中引入HSDPA技术的组网方式。最后简要分析了HSDPA技术的发展动态和未来趋势。
HSDPA (High Speed Downlink Packet Access) as the key technology that pushes the 3G to 3.5G has been deeply emphasized by communication development industry. After HSDPA was introduced to WCDMA network, the system could provide higher transition speed of data and less delay. This paper specifically analyzed several key technologies of HSDPA, and showed the operation process of HSDPA by figure 1. At present there is no WCDMA network in practice, this paper also analyzed two themes for WCDMA network introduced by HSDPA on theory. At last the prospect of using HSDPA is imaged in this paper.
