    摘要： The present disclosure relates to a method of radio communication between a first radio device and a second radio device using a first frequency resource and a first communication protocol by means of a network node, at least one of the radio devices being served by said network node. The method comprises determining a second frequency resource to use for non-network assisted device-to-device (D2D) communication between the first and second radio devices in case of a radio link failure between said at least one radio device and the network node. The method also comprises determining a second communication protocol to use for the non-network assisted D2D communication between the first and second radio devices in the case of a radio link failure between said at least one radio device and the network node.

    摘要： The present disclosure provides a method (700) and a network node (800) for coordination of channel resources between a first transmission and a second transmission sharing a common channel. The method (700) includes: detecting (S710) a first traffic status of the first transmission and a second traffic status of the second transmission during a time period; and applying (S720) one of a first frame configuration and a second frame configuration to a frame based on a probability value dependent on the first traffic status and the second traffic status. When the first frame configuration is applied to the frame, the first transmission uses the channel within the duration of the frame regardless of whether the second transmission is using the channel. When the second frame configuration is applied to the frame, the first transmission is disabled or shares the channel with the second transmission in a contention-based manner within the duration of the frame.

    摘要： A method performed by a network node for enabling Hybrid Automatic Repeat reQuest (HARQ) transmissions in a device-to-device (D2D) communication between a first wireless device and a second wireless device in a wireless telecommunications network is provided. The first and the second wireless device are served by the network node, which transmits information to at least the first and second wireless device indicating transmission resources to be used when transmitting a HARQ acknowledgement (A/N) transmission for a received data transmission in the D2D communication. The network node determines a Time-Division Duplexing (TDD) configuration for data transmissions in the D2D communication between the first and the second wireless device, and transmits the determined TDD configuration to the first and second wireless device.

    摘要： A method performed by a first wireless device for handling a device-to-device, D2D, communication with a second wireless device during handover of the first wireless device from a source network node to a target network node in a wireless telecommunications network is provided. The first wireless device interrupts the D2D communication. Then, the first wireless device determines a first uplink timing difference as the difference between the uplink timing to the source network node and the uplink timing to the target network node. Further, the first wireless device reconfigures the D2D communication based on the first uplink timing difference. Then, the first wireless device restarts the D2D communication as reconfigured. A first wireless device (121) is also provided.Further, a target network node (110, 111, 112), a source network node (110, 111) and methods therein for handling a D2D communication are provided.
