Is Dynamic Spectrum Sharing only Supported for 20 MHz Bandwidth?

Hello Experts.

Can it be implemented for smaller Bandwidth?

I have seen it for 10 MHz between NR/LTE 71 band.

Can you do L18+NR18 with DSS?

Also what happens if we have MCG and SCG split with DSS?

No Same band NSA combination is not supported.

Is DSS same like NSA?
I mean call flow?

In Huawei there’s is a feature “NSA DC with LTE and NR in the Same Band Combination”.

But I have not been able to work with it.

We have tried for B1+N1, its not working. (Most probable cause ~ UE doesn’t support same band under NSA).

Logically, we can use same frequency for both under split.

We need to try on different centre freq B1(10 MHz) + N1(10 MHz) to understand if its working or not.

First we have to establish on static config and then under DSS as well.

For DSS NSA, anchor has to be another LTE carrier.

In this case, if DSS is configured on let’s say 1800 band than achor will be of another carrier?
