Hello Guys,
Please anyone can provide MIMO Gain formula for Ericsson 4G?

2

I believe you mean MIMO Usage Percentage here?

3

Yes, please.

This is what I have for MIMO GAIN:

4

This is actually MIMO rank usage percentage.

5

Any other formula for MIMO utilisation %?

6

Massive MIMO gain is a parameter of AAU that is written in datasheet and is usually anything between 23 dB and 33 dB depending on number of elements of AAU.

7

How to be sure your MIMO 2 by 2 is working well?
Which counter need to follow?

8

Look in the counters, you should have Rank2 percentage different than zero.
Drive test tools also have windows for MIMO where you can see layers and ports used per second.

I want to share with you the final one formula I have:
