Abstract:
1. A communication device comprising: a transceiver; a determining circuit configured to determine whether the communication device may use radio resources, which are allocated to be used by a wireless bidirectional communication system in the geographical region in which the communication device is located, for radio data communication without participation by the wireless bidirectional communication system; a controller configured to control the transceiver to carry out radio data communication using the radio resources if the communication device may use the radio resources, wherein the controller is configured to control the transceiver to carry out the radio data communication using a different radio technology than the radio technology used by the wireless bidirectional communication system, wherein the different radio technology is a peer-to-peer radio technology, and wherein the transceiver is configured to receive information based on which the communication device may determine whether the communication device may use the radio resources for data communication without participation by the wireless bidirectional communication system, wherein the information specifies whether another communication device detects usage of the radio resources by the wireless bidirectional communication system.
