How is 5G SCG bearer setup time compared to LTE bearer setup time?

Hello 5G Experts,

How is 5G SCG bearer setup time compared to LTE bearer setup time?
Faster or slower?
Consider bearer setup time starting from idle mode.
5G SCG addition in 5G NSA.

Someone asked me this question yesterday as well. :slight_smile:

In NSA we have bearer modification only after sgnb addition.
Doesn’t understand which bearer setup in NSA mode… question very tricky.

5G SCG bearer setup time is always slower than LTE bearer setup time.
I think this is correct because control plane is still 4G and X2 signalling will add up for 5G SCG addition delay.
