摘要
随着异构网络的兴起,业务自适应(TA:traffic adaptation)技术成为TD-LTE技术增强的一个重要方向。如何有效地控制业务自适应技术带来的交叉时隙干扰,成为当前研究的热点。文章分析了目前比较主流的干扰控制方案,即基于小区分簇的干扰控制方案(CCIM)和基于上行功控的干扰控制方案(ULPC),提供了评估结果,并针对异构网络场景的干扰管理方法进行了初步的探讨。研究证明CCIM和ULPC可以有效的控制干扰。
As the HetNet is becoming more praetical, traffic adaptation becomes a very important way for TD-LTE enhancement. How to mitigate the inter-cross interference brought by traffic adaptation attracts many attentions. The analysis of the main interference mitigation scheme, i.e. cell clusterin interference mitigation and UL power control interference mitigation which are studied extensively, are analyzed in this contribution. At the same time, evaluation results and the interference mitigation for HetNet are provided. It is proved that CCIM and ULPC can mitigate the interference efficiently.
