Abstract
The disclosure provides a method and a device for feeding back Acknowledgment (ACK) information during switching of backhaul link subframe configuration, and the method includes during the switching of the backhaul link subframe configuration, if Uplink (UL) ACK/Negative ACK (NACK) information, which corresponds to a last transmission before the switching of one or more Downlink (DL) Hybrid Automatic Repeat Request (HARQ) transmissions, is not fed back on a UL subframe which is before the switching, feeding back the ACK/NACK information on an available UL subframe which is after the switching since Nms after the last transmission, wherein N is an integer. The disclosure achieves the effect of correctly feeding back the ACK information during switching of the backhaul link subframe configuration.
