Title: BEAM TRAINING METHOD, INITIATING DEVICE, AND RESPONSE DEVICE
Abstract:
Embodiments of the present invention relate to a beam training method and apparatus. The method comprises: an initiating device sends N first beam frames to a response device; the initiating device receives M second beam frames sent by the response device; the initiating device sends, to the response device by means of an optimal transmission sector, first feedback information used for indicating multiple preferential transmission sectors of multiple preferential transmission antennas of the response device, which are determined by the initiating device according to the second beam frames; and the initiating device receives second feedback information that is sent by the response device by means of an optimal transmission sector of the response device and that is used for indicating multiple preferential transmission sectors of multiple preferential transmission antennas of the initiating device, which are determined according to the first beam frames. The beam training method and apparatus in the embodiments of the present invention can be applied to a beam pair training process in an MIMO scenario.
