Robustness enhancements of efficient HARQ feedback
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 a downlink control information message comprising a HARQ feedback buffer index and storing a downlink HARQ feedback flag in a position within a HARQ feedback buffer that corresponds to the HARQ feedback buffer index. In this manner, multiple downlink HARQ feedback flags can be stored in the HARQ feedback buffer and subsequently transmitted to a network node in an efficient manner.
