  • Publication number: 20200228287
    Abstract: A communication method, a communications apparatus, and a device are described. The communication operation carried out by a terminal includes receiving BWP indication information sent by a network device. The BWP indication information instructs the terminal to activate a BWP and/or deactivate a BWP. The communication operation further includes sending BWP feedback information to the base station. The BWP feedback information indicates that the terminal successfully received the BWP indication information. In this way, in the event of a data transmission failure because the UE cannot receive or cannot correctly parse the BWP indication information, the UE and the base station communicating by using different BWPs can be avoided, thereby improving communication quality.
