INTERFERENCE CANCELLATION METHOD AND APPARATUS

摘要

Disclosed are an interference cancellation method and apparatus. The method comprises: a first base station determines a parameter of a channel from a transmit antenna of a second base station to a receive antenna of the first base station; the first base station receives a first signal on a first resource, the first signal comprising a first interference signal and an uplink usable signal, and the first interference signal being an interference signal generated by a downlink second signal sent by the second base station on the first resource; the first base station receives reconstruction information of the second signal sent by the second base station; and the first base station determines the first interference signal in the first signal and cancels the first interference signal according to the parameter of the channel and the reconstruction information of the second signal. According to the interference cancellation method and apparatus in the embodiments of the present invention, an interfered-with base station can cancel an interference signal generated by an uplink signal sent by an interfering base station according to related information of the uplink signal sent by the interfering base station and a parameter of a channel between the two base stations.
