    • According to one embodiment, a method for transmission/reception contention resolution in D2D communication is provided. The method includes detecting, at a device-to-device (D2D) node, re-usable cellular resources based on the scheduling information. The method also includes receiving related information from another D2D node identifying the re-usable cellular resources for the another D2D node, and identifying common and different re-usable cellular resources between the D2D node and the another D2D node. The method also includes receiving updated scheduling information, and determining, from the detected re-usable cellular resources, whether there is a simultaneous transmission/reception contention. When it is determined that there is a simultaneous transmission/reception contention, the method includes resolving the contention by dynamically selecting a direction of communication based on a preconfigured decision criteria, wherein the direction of communication is one of transmission or reception.
    • 根据一个实施例,提供了一种在D2D通信中发送/接收争用解决方法。 该方法包括在设备到设备(D2D)节点处基于调度信息检测可重用的蜂窝资源。 该方法还包括从另一个D2D节点接收标识用于另一个D2D节点的可重新使用的蜂窝资源的相关信息,以及识别D2D节点和另一个D2D节点之间的公共和不同的可重新使用的蜂窝资源。 该方法还包括接收更新的调度信息,以及从检测到的可重复使用的蜂窝资源确定是否存在同时发送/接收争用。 当确定存在同时发送/接收争用时,该方法包括通过基于预先配置的决定标准动态选择通信方向来解决争用,其中通信方向是发送或接收之一。
