Embodiment 1
[0060] According to an embodiment of the present invention, a confirmation information feedback method is provided.
[0061] figure 2 It is a flowchart of a confirmation information feedback method according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:
[0062] Step S202: Divide the multiple downlink subframes into two downlink subframe groups, and notify the base station and the terminal of the two divided downlink subframe groups and the sequence numbers of the downlink subframes included in each downlink subframe group. The two downlink subframes feed back confirmation information in the same uplink subframe, and each downlink subframe group includes at least one downlink subframe;
[0063] Step S204: The terminal uses the indication field in the uplink physical control channel corresponding to the two downlink subframe groups to feed back the data of the downlink subframe group.
[0064] Through the technical...
Embodiment 2
[0081] According to an embodiment of the present invention, a confirmation information feedback method is provided.
[0082] Figure 5 It is a flowchart of a confirmation information feedback method according to an embodiment of the present invention, such as Figure 5 As shown, the method includes the following steps:
[0083] Step S502: Divide multiple downlink subframes into multiple downlink subframe groups, and multiple downlink subframes feedback confirmation information in the same uplink subframe, and divide the divided downlink subframe groups into multiple downlink subframe groups and each downlink subframe group. The sequence numbers of the included downlink subframes are notified to the base station and the terminal, where each downlink subframe group includes one downlink subframe or two downlink subframes;
[0084] Step S504, setting a first indication field used to indicate the number of downlink subframes in the subframe group that transmit data to the terminal;
