Transmission method for confirming feedback information

The invention discloses a transmission method for confirming ACK feedback information. The method divides downlink subframes in a wireless frame into groups and limits the maximum scheduling number of the downlink subframes in the wireless frame, wherein an ACK signal of each subframe group corresponds to an uplink subframe; and the method also comprises the following steps: receiving the wireless frame sent by a base station; and feeding the ACK signal corresponding to the downlink subframe of the subframe group in the wireless frame back to the base station through the uplink subframe corresponding to the subframe group. The proposal of the invention reduces the number of the ACK signals required to be fed back by limiting the number of the downlink subframes scheduled in the wireless frame to, thus the quality of ACK feedback information is improved.
