Abstract: This application provides a data transmission method and related apparatus. The data transmission method is applied to a communications system. An access point in the communications system includes a first communications apparatus and a second communications apparatus, and a station in the communications system includes a third communications apparatus and a fourth communications apparatus. The data transmission method includes that after failing to send a first data frame to the third communications apparatus through a first channel, the first communications apparatus retransmits the first data frame, and sends a same second data frame to the second communications apparatus. The first communications apparatus receives a first notification message sent by the second communications apparatus. The first communications apparatus stops, in response to the first notification message, sending the first data frame.
