The present application provides a channel quality reporting method and device, a channel quality receiving method and device, a terminal, a service node, and a medium. The method comprises: determining a first channel quality indicator (CQI) set, the first CQI set comprising an association relationship between a CQI and channel quality parameters; and reporting the CQI on the basis of the first CQI set. The channel quality parameters comprise at least one of a modulation mode, a code rate, spectral efficiency, a modulation and coding scheme (MCS) index, a transport block size (TBS) index, and the number of times of repetition.
