How gNB intialize/select RACH common config parameters?

Hello Experts.

I had a query about RACH process.

Now, when we get the contention resolution MSG4 from gNB…

What are the parameters the gNB is verifying to pass the contention resolutions to assign a C-RNTI for a specific UE?

Is it just based on TC-RNTI verification which was assigned by gNB to UE in MSG2 or additional parameters are checked?
