Data transmission processing method and device

The present invention discloses a data transmission processing method and device, wherein the method comprises the steps of using an auxiliary user device to detect the data scheduling information that is sent by a transmission node to a target user device and comprises the scheduling information used for the target user device to transmit the data to the transmission node; and using the auxiliary user device to receive the data transmitted by the target user device to the transmission node according to the data scheduling information. According to the present invention, by introducing the auxiliary user device, at least a data transmission performance loss problem under a current transmission processing mode is solved, and the performance of the transmission node of receiving the data sent by the target user device is improved.
