How Bandwidth part is taken care in Carrier Aggregation in 5G?

Hello Experts,
How Bandwidth part is taken care in Carrier Aggregation in 5G?

Bandwidth part reffers to one carrier.
Each carrier will have its own bandwidth part.

But UE can have only one active bandwidth part, right?

Per carrier, right?
One out of 4 possible 4 configured per carrier.

Means in CA, UE having two Bandwidth part active.

4 CA will have 4 BWPs.

I have heard of CA in 5G only in mmwave for 2 CA.

4 CA with 400 MHz we have seen.
But one question: the UE will get only BWP for transfer, right?

This must also be mmwave.
Only there possible to have 400 MHz bandwidth.

Yes 38 Ghz.

Yes, only one active BWP out of 4 configured.
This is per carrier.
