Hello experts,
I am analyzing the amount of 4G traffic (data volume) that is carried when the UEs are in an active 5G NSA ENDC session. I want to understand how and why traffic division occurs at the NR-PDCP layer. “Who” decides how much traffic will go through 4G or 5G?
Can poor 5G radio conditions cause the amount of traffic sent over the 4G leg to increase?
If the UE has bad 4G radio conditions and good 5G radio conditions, is the performance in 5G affected?
Thank you so much!
