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.

Abstract: In one of the various implementations of this disclosure, a first device establishes short-range communication with a second device. The first device obtains related information of the second device based on the short-range communication. The first device sends the related information of the second device and related information of the first device to a third device. The first device then receives paging from the third device, where the paging is sent by the third device based on the related information of the second device and the related information of the first device.
