基于射频优化与PCI规划的TD-LTE网络优化案例分析

Based on rf optimization and PCI planning of TD-LTE network optimization case analysis

现阶段,与TD-LTE无线网络建设相比,无线网络优化的作用无疑更为重要.基于此,文中首先简要阐述了RF优化和PCI规划原理;还阐述了无线网络优化中两个关键性能指标参数(RSRP和SINR).把RSRP和SINR作为优化是否成功的标准,通过射频优化手段,探析了mod3干扰和乒乓切换两种无线网络故障情况.优化结果显示SINR和RSRP达到标准要求,效果明显,最终能够有效实现mod3干扰和乒乓切换故障的优化.

At present,compared with TD-LTE wireless network construction,the role of wireless network optimization is undoubtedly more important.Based on this,RF optimization and PCI planning principles are briefly described.Two key performance parameters(RSRP and SINR)in wireless network optimization are also described.Taking RSRP and SINR as the criteria for successful optimization,this paper analyzes the failure of wireless network with mod3 interference and ping-pong effect by means of rf optimization and PCI planning.The optimization results show that SINR and RSRP meet the standard requirements,and the effect is obvious.RF optimization and PCI planning can finally effectively realize the optimization of mod3 interference and ping-pong effect faults.
