A data transmission method and a network device are provided. The method includes: obtaining a to-be-transmitted first MAC packet; obtaining a first data control subframe by using field space of a first field of the first MAC packet, and obtaining a first target data subframe based on a second field of the first MAC packet, where the first data control subframe includes a sequence number of the first target data subframe; and transmitting a first frame including the first data control subframe and the first target data subframe to a target network device. A source network device uses space of the first field to generate the first data control subframe used for retransmission control.
