A vehicle-to-vehicle (V2V) communication device manages a cluster including the V2V communication device and at least one of other V2V communication device. The V2V communication device determines a cluster description specifying one or more characteristics of the cluster indicates the cluster description over a cellular network to a network node. The network node receives the cluster description and, on the basis of the received cluster description, assigns to the cluster a set of resources for V2V communication. The network node sends a resource assignment over the cellular network to the V2V communication device. The resource assignment indicates the assigned set of resources. The V2V communication device receives the resource assignment and assigns resources from the set of resources to the V2V communication devices of the cluster. Further, the V2V communication device indicates the assigned resources to the at least one further V2V communication device of the cluster.
