Webb13 sep. 2024 · The PCI itself is made up of PSS and SSS, where PSS has three values (0 to 3) while the SSS has 168 values (0 to 167). The structure of the 4G PCI is based on the following equation. PCI = (3 x SSS) + PSS This means that if the PCI value is 10, then the SSS is 3 and PSS is 1 (3 x 3 + 1 = 10).
