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.
