Abstract
Embodiments provide a method for reducing a self-interference signal in a communications system, and an apparatus. The method includes: sending a sounding signal; receiving an echo signal, where the echo signal includes a near-field reflected signal corresponding to the sounding signal. The method also includes separating the near-field reflected signal corresponding to the sounding signal from the echo signal, and determining a near-field reflection channel parameter according to the near-field reflected signal. The method also includes determining a reconstructed near-field reflected self-interference signal based on the near-field reflection channel parameter, and subtracting the reconstructed near-field reflected self-interference signal from a received second communication signal.
