Abstract: Embodiments of this disclosure provide a channel state feedback method and apparatus. The method includes: A terminal device receives first indication information from a network device. The terminal device reduces a first value of first information to a second value based on the first indication information. The second value is used to determine channel state feedback information. The first information includes channel state indicator CQI information or signal-to-interference-plus-noise ratio SINR information. The channel state feedback information determined based on the second value is more accurate than channel state feedback information determined based on the first value. This can improve accuracy of the channel state feedback information.
