Hi Experts.

When DU receives UE Context Setup Request message from gNB-CU, what next step it does.

I mean to ask what message it sends to UE (if any), before sending the UE Context Setup Response message back to gNB-DU.

I don’t think it send any messages towards UE.

It’s interaction between CU and DU only meanwhile.
