If CRS port is 2 and MIMO is 4T4R, can we get rank4?

Hi All.

If CRS port is 2 and MIMO is 4T4R, can we get rank4?

2

How come?

3

Why not rank 4 then but TxRx is 4.

But cell reference port is 2.

4

To have 4T4R you need 4 independent paths.

In your case max is 2 only.

5

So it will be rank2 only.

But can my capacity be increased in such case?

6

Not sure about that.

From where the capacity increase will come from?

Actually in this case you are working 2T2R not 4T4R.

7

I believe 4T4R will work for SINR improvement.

8

No, CRS Port must be 4.

9

Never, CRS must be 4.

Each layer need to be identified, this indicated by CRS port id.

Like port1 is layer1.

So if 4 layers, must 4 CRS port.
