Disclosed is a feedback method for interference cancellation: generating a channel quality indicator (CQI) of a service cell on the basis of received signals, where the received signals comprise a signal of the service cell signal and a signal of an interference cell, and the interference cell interferes with the service cell of a user equipment; generating interference cancellation indication information, where the interference cancellation indication information is used for indicating a state of interference cancellation executed by the user equipment with respect to the received signals; feeding back the CQI of the service cell to a network side; and, feeding back the interference cancellation indication information to the network side, where the interference cancellation indication information and the CQI of the service cell are used by the network side in scheduling the user equipment. Correspondingly, also disclosed are a related device and system. Employment of the present invention, where the interference cancellation indication information is fed back to the network side, solves the problem in the prior art of network-side scheduler inefficiency caused by CQI fluctuations in NAIC, thus implementing scheduling of UE by the network side at an increased efficiency, and fully utilizing interference cancellation gains. |
