    Abstract: This application provides a beam training method and apparatus. The method includes: generating and sending a set up frame, where the set up frame includes M pieces of time information, each piece of time information corresponds to one receiving device in the M receiving devices, each piece of time information is used to indicate a feedback information sending moment of the corresponding receiving device, each piece of time information is further used to indicate an acknowledgment information receiving moment of the corresponding receiving device; receiving a sector sweep SSW frame, generating feedback information based on the SSW frame; sending the feedback information at a feedback information sending moment indicated by corresponding time information; receiving, at an acknowledgment information receiving moment indicated by the corresponding time information, acknowledgment information. Therefore, a training time can be shortened and signaling overheads can be reduced.

    Abstract: Embodiments of this application provide a beamforming training method, an initiating device, and a responding device. The method includes: transmitting, by an initiating device, codeword indication information to each responding device in a plurality of responding devices, where codeword indication information received by a first responding device in the plurality of responding devices is used to indicate a first codeword assigned by the initiating device to the first responding device, the first codeword is used to encode a beamforming training signal transmitted between the initiating device and the first responding device, and codewords assigned to different responding devices in the plurality of responding devices are orthogonal to each other; and performing, by the initiating device, beamforming training simultaneously with the plurality of responding devices based on a plurality of codewords assigned to the plurality of responding devices.
