A transmitting user equipment (UE) device selects between a cellular communication link and a device-to-device (D2D) communication link for transmission for data from the transmitting UE device to a receiving UE device. Based on cellular channel characteristic information and D2D channel characteristic information, the UE device selects between the cellular communication link and the D2D communication link. The cellular channel characteristic information is indicative of at least a portion of a cellular communication link through a base station (eNB) and the D2D channel characteristic information is indicative of the D2D communication link between the transmitting UE device and the receiving UE device.
