Abstract: A method includes the following. A first communications device obtains an ith data packet, divides the ith data packet into N data blocks, performs fountain-code encoding on the N data blocks to generate K fountain-code codewords, generates K protocol data units (PDUs) based on the K fountain-code codewords, and sends the K PDUs to a second communications device; and after the first communications device receives first acknowledgement information sent by the second communications device, the first communications device stops, based on the first acknowledgement information, sending a to-be-sent PDU in the K PDUs to the second communications device.
