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.

Abstract: The present disclosure relates to delay measurement methods and apparatus. In one example method, a first communications device receives a data unit from a second communications device, where the data unit includes time information, the time information is used to indicate a first moment at which the second communications device sends the data unit, and the time information indicates the first moment based on a part of bits of a frame number. The first communications device determines a delay from the second communications device to the first communications device based on the first moment and a second moment, where the second moment is a moment at which the first communications device receives the data unit.

Abstract: This application provides an Ethernet data-based communication method and apparatus. The method includes: receiving, by a terminal device from a network device, a parameter used to indicate a first Ethernet compression capability; generating a first Ethernet packet based on the parameter of the first Ethernet compression capability; and sending the first Ethernet packet to the network device. Therefore, not only a manner in which the network device enables the terminal device to use an Ethernet compression capability is proposed, but also the terminal device and the network device can transmit compressed Ethernet data in a wireless network, thereby effectively saving resources.

Abstract: A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.
