摘　　要：在TD-LTE网络PCI影响分析的基础上,对PCI规划过程中需要考虑的重点因素进行了总结,提出TDLTE大规模组网情况下PCI规划的方法。理论分析结果表明:PCI规划过程中只需要满足下面4个条件就可以基本满足网络性能要求:①同一基站下各小区PCI模3不同;②相邻小区采用的m序列的循环移位值模8不同;③相邻小区PCI模6不同;④不同小区的PCI不同。TD-LTE distinguishes between cells through the PCI. We need to configure PCI properly between neighboring cells to avoid the interference and provide the best services. After theoretical analysis, the following priority orders are recommended：①Different cell has different PSS;② PCI with conflicting m0 and ml values should be avoided within the same site and as neighbors. ③ Different vshift should be used in adjacent cells. ④ The same PCI should be avoided within the same site and as neighbors.
