The present invention relates to a method, a computer readable medium, and a system of payload encoding and modulation and, more particularly, to a method, a computer readable medium, and a system of payload encoding and modulation for channel quality feedback. A method includes sending a Channel Quality Indicator (CQI) in a x-bit modulation scheme, and after sending the CQI, sending at least one CQI in a y-bit modulation scheme, the at least one CQI indicating one of an increment and a decrement of a previous CQI. The method further includes detecting a trigger event, and when the trigger event is detected, sending the CQI in the x-bit modulation scheme.
