Communication method and communication apparatus

Abstract

This application provides a communication method and a communication apparatus. The method includes: a terminal device receives a data packet of a first service from a network device; and when a transmission mode of the first service changes, the terminal device sends data packet receiving status feedback information to the network device. The terminal device feeds back a receiving status of the data packet in time, so that the network device can dynamically switch the transmission mode of the first service based on the feedback information of the terminal device, or can retransmit the data packet in time when a packet loss occurs after the switching. This improves reliability of transmitting first service data.
