LTE PCI Calculator: PSS/SSS to PCI Converter

This page provides an LTE PCI calculator for converting between PSS/SSS values and PCI values. It includes both an LTE PSS/SSS to PCI converter and an LTE PCI to PSS/SSS converter.

The LTE PCI calculator takes the Cell Group Number (Physical Layer Cell Id Group) and Cell Number (Physical Layer Sub Cell Id) as inputs. PCI is short for Physical Layer Cell Identity and is calculated based on the PSS and SSS.

• PSS: Stands for Primary Sync Sequence, which gives the cell number.
• SSS: Stands for Secondary Sync Sequence, which gives the Cell Group Number.

PSS uses 3 sequence numbers (0, 1, 2), and SSS uses 168 sequence numbers (from 0 to 167). SSS is transmitted on the 5th symbol, and PSS is transmitted on the 6th symbol of slot 0 and slot 10 of each radio frame on 72 subcarriers centered around DC.

EXAMPLE:

• INPUTS: PSS (i.e., Local Cell ID) = 1, SSS (i.e., Group Value) = 100
• OUTPUT: PCI = 301

Note: PCI values range from 0 to 503.

Formula/Equation used in LTE PCI Calculator for PSS/SSS to PCI conversion

The following equations/formula are used in this LTE PCI calculator, which helps in PSS/SSS to PCI conversion and vice versa.

Though there are three equations, they are essentially the same formulas used to calculate the LTE PCI value.

LTE PCI to PSS/SSS converter

The following calculator can be used to convert a PCI value to its corresponding PSS and SSS values.

LTE PCI to PSS/SSS conversion

EXAMPLE:

• INPUTS: PCI = 301 (Any number in the range from 0 to 503)
• OUTPUT: PSS = 1 (Any number from 0, 1, 2), SSS = 100 (Any number from 0 to 167)
