Hello dears,
Yesterday I was running into msg3 failure in 5G network. I did full reboot for gNB and it’s good.
I’m having success in msg3, and msg4 is also having success.
But the UE still not connected to 5G network - it fails.
This is because after msg4 success gNB sends msg19 which it’s CCH_MSG to UE and UE must ack to it in order to attach to 5G network.
The UE isn’t sending ack to gNB although it receieves msg19 from gNB.
Any help why UE isnt sending ack to gNB in response to msg19?
This is the last procedure of attaching to the network, once the UE sends ack in reponse to msg19 it will attach to the network but it fails for here in last step in sending ack.
It fails to send the ack to gnodeb where I drew an arrow in the photo.
