- In LTE we have 1 center frequency called : earfcn.
- In NR we have 2 center frequencies called : NR-ARFCN & GSCN.
- NR-ARFCN is applicable to the channel bandwidth.
- GSCN is applicable to the Synchronization Signals / PBCH Block (GSCN uses a coarse raster to reduce cell search times)
- SSB Can be placed automatically at the bottom, middle, top of the channel
- Also in DT will scan GSCN Carrier only.
