Abstract
Since the vehicle-to-vehicle(V2V)communication based on device-to-device(D2D)communication technology has higher requirement for reliability and time delay,it is necessary to redesign the wireless resource allocation of D2D. A resource allocation mode based on competition is discussed and improved. A channel detection mechanism at authorized frequency band was designed. The different detection windows are designed and analyzed to realize the channel detection of vehicle-user equipment(V-UE),and avoid the channel quality reduction caused by resource collision when the resource is selected in resource pool. The different windows are set for the time delay requirement according to different services to occupy the channel resource with different priorities. The result of system-level simulation shows that the mechanism can realize the time delay diffe-rence for channel occupation in different services while improving the channel quality.关键词
