本发明公开了一种HARQ反馈方式的指示、确定方法及装置，属于通信技术领域。HARQ反馈方式的指示方法，应用于发送端，包括：确定目标HARQ反馈方式，所述目标HARQ反馈方式选自第一HARQ反馈方式和第二HARQ反馈方式，所述第一HARQ反馈方式为接收端数据接收失败反馈NACK信息，数据接收成功不反馈ACK信息；所述第二HARQ反馈方式为接收端数据接收失败反馈NACK信息，数据接收成功反馈ACK信息；通过控制信息和/或数据信息将所述目标HARQ反馈方式指示给接收端。本发明的技术方案，可以使接收端获知HARQ反馈方式，并根据HARQ反馈方式进行反馈，提升系统性能。 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 i
