    Default LTE CQI value and MIMO order relation ?

    Dear,

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

    Thanks

    BR,

    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.
