What is CQI and MCS?

CQI (Channel Quality Indication) – Instead of expressing the CQI as a received signal quality, the CQI expressed as a data rate that terminal (UE) can support under the actual radio conditions. SINR is used for calculating CQI. In LTE, CQI has only 15 codes. MCS parameter is assigned based on the CQI value .
