Abstract

Embodiments of this application disclose a full-duplex self-interference cancellation method and apparatus. The full-duplex self-interference cancellation method may be applied to the field of radio frequency self-interference cancellation in a full-duplex scenario. The full-duplex self-interference cancellation method is implemented by a full-duplex self-interference cancellation apparatus with self-interference reconstruction modules of two levels, and the full-duplex self-interference cancellation apparatus is implemented by a terminal. This greatly reduces hardware implementation complexity and costs of the second self-interference reconstruction module, and improves a full-duplex self-interference cancellation capability.
