I don't know the complete use of CQI at eNodeB. Does it impact only downlink scheduling parameters or also considered while granting uplink resources ?

Hi ganesh,

CQI is only for the DL Data transmission. For UL MCS selecton eithere we should use SRS or CQI calculation based on SINR which is recieved in UL Data from PHY. You cant take a decision based on DL CQI.

As i know two type of CQI in lte, sub band CQI and wide band CQI. I wide band CQI it sends channel quality for whole bandwidth but in case of sub band CQI how UE calculates CQI?

How the CQI reporting period and the DL throughput are related?

The lower CQI reporting period, the better link adaptation, so better Modulation and Coding Scheme (MCS) assignment and higher throughput?

If this is true, the best option should be to set CQI-PMI-ConfigIndex to lower values, am I right?

CQI-PMI = Channel Quality Indicator - PreCoding-matrix-Indicator.

Actually there are three resource allocation types being used to allocate resources to UE(s) in downlink and uplink. For downlink all three (Type 0, 1 and 2) used but for uplink only resource allocation type 2 is being used.
