| 摘 要： | 现网TD-SCDMA系统的数据业务模型HSDPA时隙配置为2:4,要求R4载波也同样时隙配置,由于R4载波均为DCH信道,主要承载CS业务,该业务具有上下行对称的特征,因此,对于R4载波下行会有2个时隙闲置,导致信道资源浪费。TD-SCDMA系统R4与HSDPA共载波技术解决了HSDPA载波资源不足且另外的R4载波码道还有空余的问题,可以提高TD-SCDMA系统资源利用率。本文探讨了该技术的原理,介绍了现网的测试情况,分析了引入的效果和可能存在的风险。为TD-SCDMA网络后续载波时隙配置原则提供了很好的规划建议。

| Abstract: | Pick to the present network TD-SCDMA system data business model HSDPA time slot contiguratlon is 2：4, R4 carrier also time slot configuration, since the R4 carrier are DCH channel, main bearing CS business, the business has downlink symmetrical characteristic, therefore, for R4 carrier downlink will have 2 slot idle, leading to channel resources a waste of. TD-SCDMA R4 and HSDPA carrier technology to solve the HSDPA carrier resource scarcity and other R4 carrier code channel have any problems, can improve the TD-SCDMA system resource utilization rate. This paper discusses the principle of the technology, introduced the network test, analysis of the introduction effect and the possible risks. TD-SCDMA network for subsequent carrier time slot allocation principle provides good planning advice. |
