Abstract
In wireless device-to-device, D2D, communication data are transmitted directly from a first wireless device to a second wireless device. In response to the direct transmission of data, the second wireless device transmits feedback data indicating at least one quality of the data received in the second wireless device. More precisely, according to the invention, a radio access network node controls the direct transmission of data by means of downlink control information to the first and second wireless devices, and the feedback data are received in the radio access network node. The radio access network node preferably also uses the received feedback to control at least one of the first and second wireless devices.
