摘要:
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.
