Abstract
A radio-network node handling a data transmission to a wireless device transmits data over a number of subframes to the wireless device, and a respective control part, associated with the data of each respective subframe, the respective control part comprising a feedback index indicating a transmission time of a feedback indication. The radio-network node receives from the wireless device the feedback indication in the feedback message common for the subframes of the data transmission according to the control parts of the transmitted subframes. The feedback indication indicates feedback for each subframe of the data transmission received and the number of NACKed subframes out of the number of subframes of the data transmission. The radio-network node receives the feedback message and then decides whether or not to retransmit any of the subframes based on the feedback indication therein.
