5G NR PCI (Physical Cell ID) Calculator

Notes (3GPP‑aligned)
  • PCI range is 0–1007 (1008 identities), structured as 336 groups × 3 identities per group (NID(1), NID(2)). [1](https://www.etsi.org/deliver/etsi_ts/138200_138299/138211/18.07.00_60/ts_138211v180700p.pdf)[2](https://www.rfwireless-world.com/calculators/5g-nr-physical-layer-cell-id-calculator)
  • Mapping: PCI = 3×NID(1) + NID(2), with NID(1)∈[0,335] from SSS and NID(2)∈{0,1,2} from PSS. [1](https://www.etsi.org/deliver/etsi_ts/138200_138299/138211/18.07.00_60/ts_138211v180700p.pdf)[3](https://www.telecomtrainer.com/5g-nr-physical-cell-id-pci-explained-pss-sss-and-synchronization/)
  • Cell search derives PSS/SSS (hence PCI) inside the SSB burst as per 38.211 procedures. [1](https://www.etsi.org/deliver/etsi_ts/138200_138299/138211/18.07.00_60/ts_138211v180700p.pdf)

Note:

1- What is PCI? A physical‑layer cell identity used by UE during cell search and synchronization; it’s derived from PSS/SSS in the SSB burst.

2- Ranges and formula: NID(1)N_{\text{ID}}^{(1)} from SSS ∈ [0,335], NID(2)N_{\text{ID}}^{(2)} from PSS ∈ {0,1,2}, and PCI ∈ [0,1007], with PCI=3NID(1)+NID(2)\text{PCI} = 3N_{\text{ID}}^{(1)} + N_{\text{ID}}^{(2)}.
