Do we have CQI for uplink also?
Instead CQI, SINR reported and vendor specific MCS is to be assigned internally.
There is no CQI in UL which UE reports.
Not exactly, we have SINR in uplink.
So L2 received SINR from L1 and internally (at L2) SINR mapped with uplink CQI and CQI mapped with MCS.
Uplink CQI is not in 3GPP defined it’s MAC design.
For Uplink CQI is not there, based on SRS feedback or DMRS feedback network gets to know uplink channel quality and based on that it will assign MCS.
It depends on the Uplink link adaptation.
