Abstract: This application provides a wireless communication method and a communication apparatus. The method includes a terminal device receives a data frame from a second device by using a first device, and notifies the first device when the terminal device determines that a communication data block from the first device is not successfully received. After determining a protocol data packet corresponding to the communication data block, the first device notifies the second device that the first protocol data packet is not successfully transmitted. After determining a data unit that is in the data frame and that corresponds to the communication data block, the terminal device notifies the second device through second-step feedback.
