TD-LTE网络PCI评估研究

摘要

TD-LTE系统设计了504个PCI，PCI规划要求不冲突、不混淆，本文重点介绍了一种针对规划的PCI评估的方法。该评估方法将TD-LTE网络覆盖进行栅格化，针对每个栅格进行统计PCI的模3干扰程度，将所有栅格的模3干扰程度进行累积以表征整个网络的PCI模3干扰程度，以期指导PCI前期规划及后期优化，避免了通过现场拉网测试进行的模3干扰判断的局部性及大量的时间和人力成本，本研究以全局整体的角度来进行PCI的评估呈现整个网络的PCI模3干扰情况。%TD-LTE system defines 504 PCI.PCI planning requirements no conflict and no confusion. This article focuses on a method for the PCI assessment. The TD-LTE network coverage will be rasterized. Add up the statistical results of each grid for PCI Mod 3 disturbance degree, the extent of all raster Mod 3 cumulative interference to characterize the extent of the entire network PCI Mod 3 interference to guide PCI pre-planning and post-optimization. This study conducted a global perspective of the overall assessment PCI Mod 3 interference.
