5G（NR）PCI规划

Each 5G NR cell corresponds to a PhysicalCell ID (PCI) and it is used to distinguish cells on the radio side. The PCIplanning for 5G NR is very much similar to PCI planning for LTE and scramblingcode planning for 3G UMTS. Bad or wrong planning can affect the synchronizationprocedure , demodulation, and handover signalling and degrade the networkperforms. PCI Planning should be simpler for NR compare to LTE because thereare double as many PCIs available for allocation.

每个5G(NR)小区都有一个物理小区ID(PCI)用于无线侧标识该小区；

5G(NR)中PCI规划与LTE网络PCI、3G UMTS中的扰码规划非常相同；

错、乱、差的规划将影响信号同步、解调和切换，降低网络性能；

与LTE相比NR的PCI规划将相对简单，这是由于5G(NR)比LTE多一倍；

In 5G New Radio, there are 1008 unique PCIscompare to LTE 504 PCIs and it is given by following formulation

5G(NR)中有1008个PCI，LTE有504个
