METHOD AND DEVICE FOR INDICATING AND DETERMINING HARQ FEEDBACK MODE

摘要

Disclosed are a method and a device for indicating and determining an HARQ feedback mode, belonging to the field of communication technologies. A method for indicating an HARQ feedback mode, applied to a sending end, comprising: determining a target HARQ feedback mode, the target HARQ feedback mode being selected from a first HARQ feedback mode and a second HARQ feedback mode, the first HARQ feedback mode referring to feeding back NACK information if a receiving end fails to receive data, and not feeding back ACK information if the data is successfully received, and the second HARQ feedback mode referring to feeding back NACK information if the receiving end fails to receive the data, and feeding back ACK information if the data is successfully received; and indicating the target HARQ feedback mode to the receiving end by means of control information and/or data information. By means of the technical solution of the present invention, the receiving end can learn the HARQ feedback mode, and perform feedback according to the HARQ feedback mode, thereby improving system performance.
