Zusammenfassung:Systems and methods are disclosed for providing efficient downlink Hybrid Automatic Request (HARQ) feedback. In some embodiments, a method of operation of a wireless device in a cellular communications system comprises receiving downlink control information from a radio access node in a first subframe T. The downlink control information comprises an indication of a HARQ timing offset K. The method further comprises transmitting downlink HARQ feedback to the radio access node in a subframe T+K. In this manner, HARQ feedback can be directly scheduled by the network, which in turn enables efficient HARQ feedback.
