I’m wondering why ARFCN of LTE since we have it already why we not using it in 5g nr sa?
why we need to use new technique called GSCN?
I asked myself 'why we need this kind of additional frequency specification like this when we already have the existing frequency spec(raster) called ARFCN ?
I tried to answer myself about scanning that would take too long time but didn’t understand why it would take much and long time if we complete to use ARFCN in 5g nr sa and not using GSCN?
Appreciated for any detailed explanation about GSCN and why it’s required in 5g nr sa and what would happen if we just continue with ARFCN technique in 5g nr sa that we already have in lte ?
