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

RFSpecialist · March 17, 2021, 10:45pm

Yes, correct.

I see very few UE can support uplink 2 layers…

RFSpecialist · March 17, 2021, 10:46pm

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.

DCI format 4 used for UL MIMO in LTE.
