摘　　要：本文简要介绍了自2006年TD-SCDMA规模网络技术应用试验以来,TD-SCDMA在技术和设备方面所取得的重大进展。这一年多来,TD-SCDMA原有技术持续改进,新的技术不断涌现,如多频点技术、TD-HSDPA技术、6阵元智能天线技术、多小区联合检测技术、UpPCHShifting技术等,室内分布技术也逐渐成熟;TD-SCDMA设备性能不断提高,设备类型日趋丰富,基带拉远设备已成为发展方向,天馈系统工程实施的便利性也大有改观。The paper introduces briefly the importance developments in technology and device of TD-SCDMA since 2006 when the large-scale network testing of TD-SCDMA application started at. And since then, the old technologies of TD-SCDMA have continued improving, the new technologies have come forth continuously, such as multi-frequency, TD-HSDPA, six element smart antenna, multi-cell joint detection, UpPCH shifting, and the indoor distribution technology also has matured gradually. The performances and types of TD-SCDMA device have improved gradually and get abundant by degrees. Radio remote unit and base band unit have become the direction of TD-SCDMA device development. In addition, the convenience has changed appearances in the project implement of antenna feedback system.
