Abstract: A method, device and system for interacting link information, which are used for solving the problem that at present there is no solution for a network side to learn the link information about a terminal supporting D2D communications and how to distinguish D2D link information from D2N link information. A link information reporting method in the embodiments of the present invention comprises: a terminal supporting D2D communications determining link information which is required to be reported to a network side, wherein the link information comprises D2D link information and/or D2N link information; and the terminal sending the determined link information to the network side on a D2N link, and indicating a link corresponding to the link information to the network side. Using the method in the embodiments of the present invention enables the network side to learn the link information about the terminal supporting the D2D communications and to distinguish whether the received link information is for the D2D link or the D2N link, so that the network side can more accurately manage and schedule the D2D link and the D2N link.

Abstract: Disclosed are a data transmission method and device for device to device (D2D) communication, the method comprising: determining D2D communication destinations corresponding to a user equipment (UE) of a transmitting end; allocating a corresponding resource for each D2D communication destination; according to the resource corresponding to each D2D communication destination, generating a medium access control protocol data unit (MAC PDU) corresponding to the D2D communication destinations, and transmitting the MAC PDUs using the resource corresponding to the D2D communication destinations. The present invention separately generates a MAC PDU for each D2D communication destination of a UE of a transmitting end, thus preventing the data from one device to different D2D communication destination devices from being multiplexed into one MAC PDU, further reducing header overhead of the MAC PDU and eliminating unnecessary blind detection of a device of a receiving end, thereby saving power.
