Claim Text:
1. A method for Hybrid Automatic Repeat Request (HARQ) of a dynamic frame structure, comprising: determining, by a system device, that a predefined sub-frame of a current frame contains Downlink Control Information (DCI) indicating a frame structure; selecting, in all Time Division Duplexing (TDD) LTE frame structures, a corresponding HARQ timing for each data sub-frame between the predefined sub-frame of the current frame and the predefined sub-frame of a next frame; and receiving or sending a HARQ feedback according to the selected HARQ timing; wherein the step of selecting the corresponding HARQ timing for each data sub-frame between the predefined sub-frame of the current frame and the predefined sub-frame of the next frame comprises: for each data sub-frame between the predefined sub-frame of the current frame and the predefined sub-frame of the next frame: when an evolved Node B (eNB) sends data in a downlink data sub-frame, searching, in a TDD LTE frame structure table, downlink data sub-frames having the same number as that of the downlink data sub-frame sending the data from all frame structures, selecting, in the searched downlink data sub-frames, the downlink data sub-frame having a maximum control channel resolution of a HARQ timing, and taking a HARQ timing of a frame structure in which the selected downlink data sub-frame is located as the HARQ timing of the downlink data sub-frame being currently sending the data; or when the eNB receives the data in an uplink data sub-frame, searching, in the TDD LTE frame structure table, uplink data sub-frames having the same number as that of the uplink data sub-frame receiving the data from all frame structures, selecting, in the searched uplink data sub-frames, the uplink data sub-frame having the maximum control channel resolution of the HARQ timing, taking the HARQ timing of the frame structure in which the selected uplink data sub-frame is located as the HARQ timing of the uplink data sub-frame currently receiving the data.
