This is helpful very much. Thanks

Does that mean that QCI in LTE is replaced by QFI in 5G NR ?  Any comparison possible between NSA & SA deployments? Thanks

This is very helpful, I am wondering if there is a similar figure for downlink packet.

Thanks :)

Really clear walkthrough of the 5G traffic flow — the separation between control and user plane finally clicks when you see it end to end like this.
