| 摘要 |
The present invention relates to a method which supports device-to-device (D2D) communications. The method comprises the following steps: receiving D2D communications composition information from a base station; receiving a D2D scheduling assignment (SA) grant from the base station; judging whether a same or different SA is transmitted on a first multi-transmission opportunity based on the D2D communications composition information and the D2D SA grant; and transmitting the same or different SA to a reception terminal on the first multi-transmission opportunity based on a judgment about whether the same or different SA is transmitted. According to the present invention, the method can support the flexible D2D communications, and improve reliability or transmission efficiency of the D2D communications. |
