Devices and methods for network-assisted D2D communications by devices operating in an ad hoc mode or a network-assisted mode

The application relates to devices and methods for network-assisted D2D communication. A communication device is configured to select a data channel communication resource from a plurality of data channel communication resources which are reserved for D2D data channel communications. The communication device is configured to select an ad-hoc mode control channel resource from a plurality of ad-hoc mode control channel resources which are reserved for D2D ad-hoc mode control channel communications. The communication device is further configured to broadcast, using the selected ad-hoc mode control channel resource, a communication resource selection message including information about the selected data channel communication resource to the plurality of communication devices. The communication device is further configured to communicate with at least one of the plurality of communication devices using the selected data channel communication resource.
