Hi Dear Friends n Experts.
Is PRACH SCS the same as Band numerology / SCS?
Or should I ask can we have different SCS for PRACH and RB (PUCCH)?
Totally different.
SCS need to same for carrier = PDCCH = SSB / PBCH = PDSCH, like if it’s TDD band then SCS need to be 30 kHz.
PRACH SCS depends on long or short PRACH format used, like it can be 1.25 kHz as per PRACH format used.
Ok, thanks.
Then that means we can use long PRACH (1.25 / 5 kHz SCS) in FR1 band having SCS (30 kHz). Both can be different?
Yes, correct.
Perfect, thanks a lot
