network node to signal hybrid auto-repeat request recognition feedback and related method, wireless device to perform a hybrid auto-repeat request procedure and related method and computer-readable memory

摘要

systems and methods for efficient signaling of the hybrid automatic repeat recognition request (harq-ack) for an uplink data transmission are described. in some embodiments, a harq-ack feedback signaling method for an uplink data transmission sent from a wireless device to a radio network node comprises obtaining harq-ack feedback for the link data transmission upstream, encode the harq-ack feedback obtained for an unused bit combination of a field on a downlink control channel, and transmit the downlink control channel to the wireless device. the embodiments of the present invention allow the energy saving of the wireless device using positive harq-ack feedback without increasing the static downlink control signaling overhead and without reducing coverage for the downlink control information.
