Abstract: a method and a board for high-speed link auto-negotiation, includes: setting, by a first board, a port rate to a public rate supported by both the first board and a second board; sending, by the first board, a first auto-negotiation packet to the second board according to the public rate, where the first auto-negotiation packet carries a rate supported by the first board, so that the second board determines, a highest rate supported by both the two boards, and sets the port rate to the highest rate; receiving, by the first board, a second auto-negotiation packet that is sent by the second board according to the public rate, which carries the rate supported by the second board; determining, by the first board, according to the rate supported by the two boards, the highest rate supported by both the two boards, and setting the port rate to the highest rate.

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.
