    Abstract: Embodiments of the present invention disclose a directional direction selection method, apparatus, and system. The method includes: sending L groups of pilots in an omnidirectional direction manner, where the L groups of pilots are received by UE by using L directional directions, and the L groups of pilots are used by the UE to switch to a directional direction with best channel quality in the L directional directions; sending, by a base station, S groups of pilots by using S directional directions respectively; determining, by the base station, an optimal directional direction in the S directional directions according to the channel quality corresponding to the S groups of pilots; and switching, by the base station, to the optimal directional direction in the S directional directions.

    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.
