A. SMF derives the QoS profile of a QoS Flow from a PCC rule and sends it to NG-RAN.
B. NG-RAN uses the QoS profiles to create mapping between QoS Flow IDs and data radio bearers.
C. Each QoS profile includes a 5G QoS Identifier (5QI) and an Allocation and Retention Priority (ARP).
D. NG-RAN sends the QoS profiles and corresponding QoS Flow IDs to the UE.

B. Both eNB and gNB are connected with S1-U interfaces to SGW.
C. Dual connectivity is used for high throughput services such as eMBB.
D. When NR radio quality becomes sub-optimal, gNB decides to split the bearer.
