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.

Abstract: A method for retransmitting a packet on a wireless fidelity link includes receiving a packet retransmission request sent by a user terminal and determining a packet that needs to be retransmitted, detecting a downlink quality indicator on a gateway side of a first wireless fidelity link and a downlink quality indicator on a gateway side of a second wireless fidelity link, determining a link for retransmitting the packet, based on the downlink quality indicator on the gateway side of the first wireless fidelity link and the downlink quality indicator on the gateway side of the second wireless fidelity link, and sending, to the user terminal on the determined link for retransmitting the packet, the determined packet that needs to be retransmitted.
