UE Initial Cell Search
Apr 8, 2024
- When a UE is switched on, it searches for Primary Synchronisation Signal (PSS) and Secondary Synchronisation Signal (SSS). PSS and SSS are present in Primary Broadcast Channel (PBCH)
- Synchronisation table, which is a mapping between Global Synchronisation Channel Number (GSCN) and Absolute Radio Frequency Channel Number (ARFCN) helps the UE to determine the location of PSS and SSS.
- Master Information Block (MIB) and System Information Block (SIB) present in PSS and SSS helps the UE to determine common Resource Block (RB) grid.
