摘要
网内前向干扰是影响FDD-LTE网络容量和用户感受的重要因素,对FDD-LTE的前向干扰和容量进行定量分析,建立了在不同负荷条件下的前向干扰模型,对理想组网结构和实际运营网络结构进行了仿真。仿真结果与华为实际路测结果基本一致,且该模型为LTE网络实际运营负荷下的干扰及容量提供了精度较高的定量评估手段,对业务发展和网络投资与优化有重要的指导意义。
The forward interference is an important factor that affects the FDD-LTE network capacity and user experience. FDD-LTE forward interference and capacity were analyzed. A forward interference model was proposed under various network loads. Simulation result of ideal and practical network is approximate to the road test result. The model provides evaluation method with high precision for practical business network and it can provide important information for business development and network invest.
