Performance Evaluation between the Co-existing Systems of TD-HSDPA and TD-SCDMA
首发时间:2009-07-29
Abstract:As an important step in the evolution of TD-SCDMA system, TD-HSDPA system offers higher data rate and network capacity. TD-SCDMA network is now under deployment in China. And TD-HSDPA will also start to be deployed in the near future. Research on the co-existence between these two above mentioned systems is very important to the deployment of TD-SCDMA network and TD-HSDPA network. But related research is quite limited. In this paper, the system performance of TD-SCDMA system and TD-HSDPA system is studied when they are co-existing. Some important simulation assumptions, including the deployment scenario, the propagation models and the interference models are described in this paper. Besides, impact on system capacity due to the co-existed systems is investigated. And finally, some advises on the deployment of TD-HSDPA and TD-SCDMA systems are given.

TD-SCDMA/TD-HSDPA共存系统性能评估
摘要:TD-SCDMA网络的部署正在全中国范围内进行,而由TD-SCDMA向TD-HSDPA网络的升级也将在近期展开。TD-HSDPA是TD-SCDMA R4的演进系统,由于TD-SCDMA R4以语音承载为主,而HSDPA以数据承载为主,两者系统特性有一定差异,另外,干扰评估准则也不尽相同,所以两系统之间的干扰有别于两个R4系统的共存。研究TD-HSDPA与TD-SCDMA系统之间的干扰问题,可以为我国的频率规划和运营商的网络建设提供重要的参考依据。本文主要研究2GHz TD-SCDMA与TD-HSDPA的共存问题,对仿真假设(包括仿真场景,传播模型,干扰模型等)进行了详细的描述,并给出了相应的仿真结果,最后给出结论和建议。
