    • A network node (700), a wireless device and methods therein for handling radio resources when feedback signalling is employed to indicate either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted by the wireless device. The network node (700) assigns a shared radio resource to a group of wireless devices (702) to be used for retransmission in case the feedback signalling for a transmission of data indicates a NACK. When receiving a set of concurrent transmissions of data from the wireless devices (702) where a subset of the concurrent transmissions of data is not received correctly, the network node (700) transmits a NACK to those wireless devices that transmitted the subset that was not received correctly. The network node (700) then receives on the shared radio resource a retransmission of at least one of the concurrent transmissions of data in the subset that was not received correctly from at least one wireless device to which said NACK was transmitted.
    • 网络节点(700),无线设备及其中用于当反馈信令被用来指示确认,ACK或非确认NACK时处理无线电资源的方法, 由无线设备传输的数据。 在用于传输数据的反馈信令指示NACK的情况下,网络节点(700)将共享无线电资源分配给一组无线设备(702)以用于重传。 当从无线设备(702)接收到数据的并发传输的子集没有被正确接收到的一组并发传输时,​​网络节点(700)向传输该子集的那些无线设备发送NACK 正确接收。 然后,网络节点(700)在共享无线电资源上接收至少一个并行传输的数据中的至少一个数据的并发传输,该传输没有从传输所述NACK的至少一个无线设备正确接收。

    • A method and a radio node (110) for managing resources for D2D discovery in an ad-hoc radio communication munication network (100). The radio node (110) receives beacon signals from a number of further radio nodes (120, 130, 140). A respective beacon signal includes values indicating power received at the respective further radio node (120, 130, 140) for each resource of the amount of resources. The radio node (110) calculates, for each respective further radio node (120, 130, 140), values of SINR based on the values indicating power received at the respective further radio node (120, 130, 140). The radio node (110) selects at least one resource out of the amount of resources to increase number of discovering further radio nodes (120, 30, 140) and/or to increase average SINRover the further radio nodes (120, 130, 40). The radio node (110) broadcasts a further beacon signal on the selected at least one resource.
