UL PRB difference in SA vs NSA


With 90 MHz NR carrier, I am getting:

  • max scheduled PRB in UL in SA = 245
  • max scheduled PRB in UL in NSA = 219

Any reason for this UL PRB change in SA vs NSA?

Is it single user in both case scheduled?

Yes, with UL UDP.

Ideally I didn’t find any such difference in term of UL PRB for Nsa vs SA.
If we check BSR value reported by UE if its same then difference in PRB allocation is concern considering radio enviornment same, same UL modulation used.

Yes, right.
