A NETWORK NODE, A WIRELESS DEVICE AND METHODS THEREIN FOR ENABLING AND PERFORMING HARQ TRANSMISSIONS IN A D2D COMMUNICATION BETWEEN WIRELESS DEVICES IN A WIRELESS TELECOMMUNICATIONS NETWORK

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.
