Abstract: A data transmission method and a device where during downlink data transmission, a network side device generates second information based on first information and a second identifier and sends the second information to a second device, and in the sending process, the second information passes through a first device. In the process, the second information is generated by the network side device based on the first information and the second identifier of the second device. Therefore, when the second information reaches the first device, the first device can identify the second device as a destination of the second information. Network quality of service different from that of the first device is provided to the second device by distinguishing data of the first device and data of the second device.
