    Abstract: Embodiments described provide a data transmission method, a network device, and a terminal device. The method includes: sending, by a network device, control information corresponding to target data to a terminal device on a control resource, where the control resource and a data resource have a correspondence, and the control resource is used by the terminal device to determine the data resource on which the target data is received; and sending, by the network device based on the correspondence, the target data to the terminal device on the data resource. In the embodiments, after sending the control information corresponding to the target data on the control resource, the network device can send the target data on the data resource based on the correspondence between the control resource and the data resource, so that terminal devices having different bandwidth capabilities are able to receive the target data.

    Abstract: A device-to-device (“D2D”) communication method includes sending first control signaling to first user equipment, sending second control signaling to second user equipment, and sending N pieces of third control signaling to N third user equipment. The method also includes receiving first channel quality feedback signaling fed back by the first user equipment, second channel quality feedback signaling fed back by the second user equipment, and receiving N pieces of third channel quality feedback signaling fed back by the N third user equipment. The method further includes detecting channel quality between the D2D user equipment and a base station, and determining a D2D communication mode based on the feedback signaling and the channel quality between the D2D user equipment and the base station. The method additionally includes determining a D2D communication mode, and determining target third user equipment paired with the D2D user equipment based on the determined D2D communication mode.
