    Abstract: A method and apparatus related to a first radio network node serving a first UE in a first mobile radio network for enabling a D2D communication with a second UE served by a second radio network node in a second radio network. The first radio network node establishes a connection with the second radio network node. The first UE (230) requests to the first radio network node to enable a communication with the second user equipment (290). The first radio network sends a first message comprising information related to the first UE (230) to the second radio network node (280) for configuration of the second UE (290). The first radio network node receives a second message for configuration of the first UE (230) and sends to the first UE (230) a third message related to the second UE.

    Abstract: METHODS AND ARRANGEMENTS FOR AD-HOC WIRELESS NETWORKS. THE PRESENT INVENTION RELATES TO METHODS AND ARRANGEMENTS IN AN AD-HOC NETWORK WHEREIN THE AD-HOC DEVICES ARE CONFIGURED TO ENTER DRX MODE. THE BASIC CONCEPT OF THE EMBODIMENTS OF THE PRESENT INVENTION IS TO LET A NODE INITIATE AND MAINTAIN TRANSMISSION OF A SPECIFIC REFERENCE SIGNAL PATTERN DURING THE DRX OPERATION OF AN AD-HOC DEVICE, REFERRED TO AS A UE. THE TRANSMISSION OF THE REFERENCE SIGNAL PATTERN ENABLES THE UE TO MAINTAIN SYNCHRONIZATION. PUBL.

    Abstract: A method and a base station(800) for supporting communication over a cellular radio link between the base station and a first wireless device (D1). The base station (800) obtains a first path gain (G1) of a cellular radio link to the first wireless device (D1), a second path gain (G2) of a cellular radio link to a second wireless device (D2), and a third path gain (G12) of a Device-to-Device, D2D radio link between the first wireless device (D1) and the second wireless device (D2). When the first, second and third path gains satisfy a threshold condition, the base station (800) instructs the second wireless device (D2) to apply network coding on first data (x1) transmitted from the first wireless device (D1) and to transmit a network coded form of the first data (x1). The base station (800) then receives a radio signal with the first data (x1) transmitted from the first wireless device (D1), and uses the network coded form of the first data transmitted by the second wireless device (D2) for decoding the first data (x1).

    Abstract: A method of a network node adapted to provide assistance of device to device communication is disclosed. The method comprises receiving from a first wireless communication device adapted to perform device to device communication one or more first global device identities associated with the first wireless communication device and allocating one or more first local device identities to the first wireless communication device based on the received global device identities (330). The method also comprises storing in association to the network node a mapping between each received one or more first global device identity and each allocated one or more first local device identity transmitting information indicative of the allocated one or more first local device identities to the first wireless communication device and transmitting information indicative of at least one of the allocated one or more first local device identities to a first group of one or more other wireless communication devices (350). A method of a wireless communication device adapted to perform device to device communication is also disclosed. The method comprises receiving from a network node information indicative of at least one local device identity allocated to another wireless communication device and monitoring device to device communication beacon signaling based on the received at least one local device identity.

    Abstract: A method of a wireless communication device adapted to perform device-to-device communication is disclosed. The method comprises transmitting an indication of device-to-device communication capability to a network node, receiving one or more beacon parameters allocated to one or more second wireless communication devices adapted to perform device-to device communication, monitoring device-to-device communication beacon signaling based on the received beacon parameters, and performing at least one radio operation task based on measurements of the monitored device-to-device communication beacon signaling. The at least one radio operation task may comprise using the measurements of the monitored device-to-device communication beacon signaling to select or re-select one of the one or more second wireless communication devices for device-to-device communication, and/or transmitting a beacon measurement report to the network node based on the monitored device-to-device communication beacon signaling. Another method of a wireless communication device comprises receiving one or more beacon parameters allocated to the wireless communication device from a network node, transmitting device-to-device communication beacon signaling based on the received beacon parameters, and receiving a beacon measurement report from the network node indicating detection of the transmitted beacon by one or more second wireless communication devices. Corresponding methods of a network node are also disclosed as well as corresponding arrangements, wireless communication devices and network nodes.
