LTE CQI value and MIMO order relation ?

[fahmi]

Dear,

What is the impact of activating MIMO 4x4 on CQI calculation and reporting ? any adjusment for CQI related Parameters after MIMO 4x4 ?

Thanks

There will be 4 CQI reports.

Adding to this:

There is no direct relation between CQI and MIMO (ranks). Given the fact a UE has a high reported CQI it does not mean that it is suitable for spatial multiplexing. For that you will need to look at the RI (Rank Indicator). For sure a high CQI UE will have higher chance to be suitable due to the higher SINR, but that alone is not enough.
