Can same Qualcomm expert clarify to me why MAC TA value jump to ~30 when UE move from LTE to NSA?
On LTE was around 3.
Firstly I thought it some issue with the equipment in the lab but the same thing I saw on the other example made on different vendor and location.
Both examples on Oneplus 8
You mean for NR RACH procedure you get TA around 30 instead of 3?
For NR RACH I got normal value, but later on MAC messages I see 29-35.
Isn’t TA multiplied by 10?
But why different for LTE and NR?
Have a look and TA @ gNB to confirm if you’re not looking at logging differences.
For SCS 30KHz:
NR TA = 2 x LTE TA + 25
Thanks @O.B , this is helpful
