Abstract: Embodiments of this application provide an information transmission method and a network device. The method may include: listening, by a second network device, to a first frame sent by a first network device, where the first frame is used to indicate whether the first network device supports communication between network devices; and if both the first network device and the second network device support the communication between the network devices, transmitting, by the second network device, information with the first network device.

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.
