Method and Device for Hybrid Automatic Repeat Request of Dynamic Frame Structure

摘要

The present disclosure discloses method for Hybrid Automatic Repeat Request (HARQ) of a dynamic frame structure, including: determining, by a system device, that a predefined sub-frame of a current frame contains Downlink Control Information (DCI) indicating a frame structure; in all Time Division Duplexing (TDD) frame structures, selecting 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. The present disclosure also discloses a HARQ device of a dynamic frame structure. Through the solution of the present disclosure, during switching the dynamic frame structure of a TDD system, a corresponding HARQ timing can be selected for each data sub-frame in each frame, thus increasing NN resolution and real-time performance, ensuring a quantity of a HARQ process, and reducing transmission delay and blocking rate.
