Thanks.
The red number between () is layers, right?

[RFSpecialist]

Yes, correct.

[Hainm]

I see very few UE can support uplink 2 layers…

[RFSpecialist]

Yes indeed mostly Sony mobiles supports 2 layers in UL.

How do you know?

These are not MIMO layers i suppose?
Don’t think many handsets or network suppose UL MIMO.
