Abstract: The present invention discloses a data packet transmission method. A terminal device receives uplink scheduling resource configuration information sent by a base station; the terminal device determines a data transmission priority corresponding to each of N logical channels; the terminal device loads data on M logical channels in the N logical channels into a media access control protocol data unit (MAC PDU) based on the data transmission priority corresponding to each of the N logical channels; and the terminal device sends the MAC PDU to the base station on the uplink scheduling resource by using the physical communication characteristic of the uplink scheduling resource. According to the embodiments of the present invention, transmission of data on a logical channel with a high priority is ensured, and a waste of resources is avoided, thereby matching a resource with a service to the utmost.
