CQI Vs Modulation - Ue Category

The document contains tables mapping Channel Quality Indicator (CQI) values to modulation schemes and transport block sizes for different UE categories in LTE networks. The tables show that higher CQI values generally indicate better channel conditions and are mapped to higher order modulation schemes like 16-QAM which provide higher data rates. The transport block sizes also increase with higher CQI values to provide more capacity for transmitting data.
