4T4R MIMO in LTE with no rank 3 and 4

Hi experts

Im facing some problem with overshooting and low uplink throughput in some sites.

While trying to optimize i saw abnormal values for counter pmRadioUeRepRankDistr showing samples only for Rank 1 and Rank 2 and nothing for rank 3 and 4.

But using CQI counter it showing normal Values from 1 to 15.

We r using MIMO 2*2. \E

Can you explain this statement better? there is no MIMO 4T4R in the low bands???
I’m about to implement MIMO 4T4R in the L800 band and if your statement is true, there’s no point in moving forward.

Yes , there’s very low penetration of UEs support low band 4t4r …

So there’s no rank 4 counting .
The drop and interference will highly increase with the deployment.

CQI and throughput increased .

Take one site as trial and see the results and assess if you accept this situation or not in your network.

Thanks for your support, but is it possible to provide some report for me to dispute with the vendor on this matter?
