Abstract: Embodiments of the present invention provide a channel state information (CSI) feedback method and apparatus, user equipment, and a base station. The method, performed by a user equipment device, includes: pre-synchronizing, between the user equipment device and a base station, a basis matrix that includes sparsity of CSI in a frequency domain and a space domain; receiving pilot information from the base station; determining, according to the pilot information, a CSI information matrix that includes information about the frequency domain and the space domain of CSI; determining data by using the CSI information matrix; and feeding back the data to the base station, so that the base station restores the corresponding CSI information from the data by using the basis matrix.

Abstract: Embodiments of the present invention provide a signal processing method and a base station. By using respective sparse characteristics of a user signal and an interference signal, the user signal and the interference signal are iteratively recovered, that is, the interference signal is first fastened, and the user signal is recovered; and then the user signal is fastened, and the interference signal is recovered. In this way, an iteration cycle is repeated until the recovered user signal and the recovered interference signal meet a preset condition, thereby effectively improving interference cancellation performance, achieving relatively good interference suppression.
