Abstract: This application provides an acknowledgment packet transmission method and a communications device. The method includes: receiving, by a first device, data sent by a second device; sending, by the first device, the acknowledgment packet to the second device, where the acknowledgment packet includes an acknowledgment field, the acknowledgment field carries data lengths of K groups of data packets, and the data lengths vary with a data amount included in each group of data packets received/lost by the first device.

Abstract: This application provides a data transmission method and system, an apparatus, and belongs to the field of communications technologies. The method is applied to a terminal, a wireless link is established between the terminal and an access control point device, a transmission control protocol (TCP) connection is established between the terminal and a server, and the wireless link is used to bear the TCP connection. The method includes: determining, by the terminal, link state information of the wireless link by using a link layer, and sending the link state information from the link layer to a transport layer. The method also includes: sending, by the terminal to the server by using the transport layer, a link notification corresponding to the link state information. In this application, data transmission efficiency can be improved.
