Abstract: The present invention discloses a channel state information (CSI) feedback method. The CSI feedback method includes: receiving, by user equipment (UE), a reference signal broadcast by a base station; performing channel estimation on a radio channel between the base station and the UE by using the reference signal, to obtain CSI and a channel quality parameter; adjusting the channel quality parameter according to a channel quality weight parameter, to obtain a channel statistic quality parameter; and when the channel statistic quality parameter exceeds a channel quality threshold, feeding back the CSI to the base station. In the present invention, because a channel quality parameter is dynamically adjusted by using a channel quality weight parameter, and it is selected, according to a result of comparing an adjusted channel statistic quality parameter with a channel quality threshold, whether to report CSI. UEs in a system can be evenly scheduled.
