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: The present disclosure relates to wireless communication methods, terminal devices, and network devices. In one example method, a network device sends timing advance timer (TAT) configuration information to a terminal device, where the TAT configuration information is used by the terminal device to configure duration of a TAT. The terminal device receives the TAT configuration information sent by the network device. The terminal device configures the TAT based on the TAT configuration information, and asynchronously sends uplink data to the network de vice based on a running status of the TAT. The network device receives the uplink data sent by the terminal device based on the TAT configuration information.

Abstract: This application provides a communication method and a communication system. A central unit (CU) obtains a quality of service (QoS) parameter of a QoS data flow and performs mapping the QoS data flow to a bearer based on the QoS parameter of the QoS data flow. The CU determines a QoS parameter of the bearer based on the QoS parameter of the QoS data flow and sends a context setup request message to a distributed unit (DU), wherein the context setup request message comprises the QoS parameter of the bearer, the QoS parameter of the QoS data flow and the mapping relationship between the QoS data flow and the bearer.

Abstract: Embodiments of this application provide a communications method and apparatus. The method includes: determining a target cell based on measurement results of N measured cells and a preset value when there is a first cell satisfying a report trigger condition; and sending a measurement result of the target cell to a base station. Based on the foregoing technical solution, the terminal may not only send the measurement result of the cell satisfying the trigger condition to the base station, but also send a measurement result of another cell to the base station. In this way, a quantity of cells that can be selected during determining of handover can be increased, to help the base station select a suitable cell for the terminal.

Abstract: Example data processing methods and apparatuses are disclosed. In one example data processing method, a first terminal obtains packet delay budget adjustment information, where the packet delay budget adjustment information is used to indicate an adjusted packet delay budget, a packet delay budget adjustment amount, or a packet delay budget adjustment range. The first terminal adjusts a size of a jitter buffer based on the packet delay budget adjustment information, and then buffers data based on the adjusted jitter buffer.

Abstract: Example data sending methods and apparatus are described. One example method includes sending a first message to a network device by a terminal device. The first message is used to indicate information about remaining time of each of one or more data packets. The remaining time of each of the one or more data packets is used to indicate that the terminal device needs to finish sending each of the one or more data packets before the end of the remaining time. The terminal device obtains information about a resource configured by the network device for the terminal device, wherein the resource is used to send each of the one or more data packets before the end of the remaining time.

Abstract: This application provides a communication method and a communications apparatus. The communication method may includes receiving, by a first forwarding device in a mobile network, a first data packet, where the first data packet carries first data from a first terminal device, the first data packet includes a target field, information carried in the target field is used to determine target information. The target information may include information about at least one second terminal device or information about a first area, the second terminal device is a terminal device to which the first data needs to be sent, and the first area is an area to which the first data needs to be broadcast. The communications method may also include sending, by the first forwarding device, a second data packet based on the target information, where the second data packet carries the first data, so that the first forwarding device does not need to send the first data to a device such as a server configured to implement a routing and addressing function, thereby reducing a transmission latency.

Abstract: A communications method and apparatus. The communications method includes: transmitting a first request to a network device through a first resource, where the first request is used to request beam failure recovery of a first cell or is used to request system information of the first cell, the first resource is a resource of a second cell, and the first cell and the second cell are serving cells of a same terminal; and receiving a first response corresponding to the first request from the network device. Therefore, when a terminal has a plurality of serving cells, the terminal may transmit a request across cells (or across carriers), to improve transmission reliability.

Abstract: Embodiments of the present invention provide a method for handover between secondary base stations, a network device, and user equipment. A network device instructs each of at least one candidate secondary base station to make a prior path handover preparation, so that each of the at least one candidate secondary base station waits to be selected by user equipment as a target secondary base station. The path handover preparation includes at least one of the following: preconfiguring an access resource for the user equipment or establishing a data transmission channel with the network device. The user equipment is handed over to the target secondary base station in the at least one candidate secondary base station according to configuration information of each of the at least one candidate secondary base station when the user equipment needs path handover.
