Abstract: A data transmission method, a data receiving device, and a data sending device are disclosed. An RLC protocol entity unit of a data receive end receives a TCP acknowledgement from a TCP protocol entity unit of the data receive end; and the RLC protocol entity unit sends indication information to an RLC protocol entity unit of a data transmit end, where the indication information is used to indicate whether the RLC protocol entity unit needs to generate a TCP acknowledgement. The RLC protocol entity unit receives the indication information from the RLC protocol entity unit, and sends the TCP acknowledgement to a TCP protocol entity unit of the data transmit end based on the indication information, to ensure that the TCP protocol entity unit ultimately receives only one TCP ACK for one TCP data packet.
