Abstract
A channel quality reporting method, a channel quality receiving method, a terminal, a service node, and a medium are provided. The channel quality reporting method includes: determining a first channel quality indicator (CQI) set, the first CQI set including an association relationships between CQls and a channel quality parameter; and reporting the CQI based on the first CQI set. The channel quality parameter includes at least one of a modulation mode, a code rate, a spectral efficiency, a modulation and coding scheme (MCS) index, a transport block size (TBS) index, or a repetition number.
