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.
