Abstract: Embodiments of the present invention provide a data transmission method and apparatus, and relate to the communications field. The method includes: obtaining configuration information; establishing at least one logical channel according to an identifier of each logical channel and the corresponding transmission mode indication; obtaining a transmission resource according to the transmission mode indication of a logical channel to which device-to-device (D2D) buffered data belongs; and sending the D2D buffered data by using the obtained transmission resource. A problem that a resource allocation mode used by a terminal during D2D communication is relatively single and is not flexible enough is resolved, and the terminal can use different resource allocation modes according to a logical channel granularity, so that not only consumption of signaling resources of a network device can be reduced, but also QoS requirements of some services that require relatively high QoS can be satisfied.

Abstract: Embodiments of this application relate to the field of communication technologies, and disclose a communication method and apparatus, so that corresponding PDCP entities of a first terminal and a second terminal use consistent input parameters when executing security algorithms, thereby ensuring normal communication on a sidelink SL and improving communication reliability. A specific solution is as follows: A first terminal determines a logical channel identifier LCID meeting a preset condition, where a first packet data convergence protocol PDCP entity of the first terminal is associated with two or more logical channels LCHs; the first terminal receives a first data packet from a second terminal; and the first PDCP entity of the first terminal parses the first data packet based on the LCID.

Abstract: A data processing method includes receiving by an access network device a vehicle-to-everything (V2X) communication parameter of a group member device. The method also includes storing, by the access network device, the V2X communication parameter with context about a group to which the group member device belongs. The V2X communication parameter is used for allocation of a ProSe communication 5 (PC5) resource to the group member device.
