Hi Experts.
Does any vendor have a formula/counter to capture tDCprep-expiry (30) in sgNB Addition Preparation Success Rate?
radio network cause: tDCprep-expiry (30)
This is related to DSS(LTE+NR) if CRS rate matching is missing in IE of UE capability this timer will expire.
you can check below KPI
