    Abstract: Embodiments of the present invention provide a method for reducing a self-interference signal in a communications system, and an apparatus. The method includes: sending a sounding signal and a first communication signal; receiving an input signal; separating a near-field reflection signal corresponding to the sounding signal from an echo signal of the input signal; determining, based on the near-field reflection signal, a near-field reflection channel parameter; determining, based on the near-field reflection channel parameter, a reconstructed near-field reflected self-interference signal; and subtracting the reconstructed near-field reflected self-interference signal from a received second communication signal. The present invention can effectively recognize and reconstruct a near-field reflection signal, thereby reducing a near-field reflected self-interference signal in self-interference.

    Abstract: A wireless communications system, a scheduling method, a wireless communications method, and an apparatus are provided. Frequencies of operating channels of a plurality of radio access nodes included in a first radio access cell in the wireless communications system are the same. A controller of the system may indicate one radio access node in the first radio access cell to serve as a transceiving access node in a first scheduling period, and indicate another radio access node to serve as an uplink access node. Because in the first scheduling period, the transceiving access node can perform uplink communication and downlink communication with a wireless terminal, and the uplink access node cannot send a radio signal, a problem of co-channel interference can be effectively solved.
