Abstract:
1. A method, comprising: determining position of a device within a cluster of multiple devices and storing the determined position in a computer readable memory, wherein the cluster of multiple devices communicate directly amongst themselves in a D2D network operating under control of a cellular network and includes a cluster head that receives the downlink radio resource from the cellular network and informs the device of the determined position of the device within the cluster via D2D signaling, the cluster head informing the cellular network of the uplink radio resource to be associated with the device; and mapping an uplink radio resource from a downlink radio resource in dependence on the determined position of the device within the cluster of multiple devices so that uplink control resources for communicating with the cellular network are assigned for the device also in direct D2D communication with at least one other device in the D2D network.
