Abstract: This application discloses a Wi-Fi communication method and a device, and relates to the field of wireless communication technologies. In the method, a first communication device is configured to: generate a first physical frame, and send the first physical frame. The first physical frame includes signaling information and a plurality of training sequences used for channel estimation, the signaling information indicates a quantity of space-time streams and a quantity of the plurality of training sequences, and the quantity of the plurality of training sequences is greater than the quantity of space-time streams. This helps improve accuracy of an algorithm such as channel estimation in a communication system, to improve a demodulation capability of a communication device, and ensure data demodulation effect.
