Abstract: This application provides a data transmission method and an apparatus. The method includes: A first central unit receives data from a user plane function network element, and then determines time information corresponding to the data, where the time information is used by a first distributed unit and a second distributed unit to synchronously transmit the data. Further, the first central unit separately sends the data and the time information to the first distributed unit and the second distributed unit. The first distributed unit and the second distributed unit send the data to a terminal device based on the time information. According to the method, the first distributed unit and the second distributed unit can perform synchronous transmission to the terminal device, to improve data transmission reliability.

Abstract: This application provides a communication method and a communication apparatus. In the method, after a DU sends a first handover message to a terminal device, the DU receives a second handover message from a CU, where the first handover message indicates to hand over the terminal device from a source cell to a first target cell in a first manner, the first manner includes an L1 and/or L2-based cell handover manner, the second handover message indicates to hand over the terminal device from the source cell to a second target cell in a second manner, and the second manner includes an L3-based cell handover manner. The DU determines that a cell handover manner of the terminal device is the first manner or the second manner.

Abstract: Example message transmission methods and apparatus are provided. One example method includes obtaining a first correspondence by a core network device, where the first correspondence includes a correspondence between target device information and first time sensitive networking (TSN) domain information. The target device information is used to identify a target device, and the first TSN domain information is used to identify a TSN domain to which a first TSN device belongs. The core network device receives a multicast message from a second TSN device, where the multicast message includes second TSN domain information which is used to identify a TSN domain to which the second TSN device belongs. The core network device sends the multicast message to the target device when determining, based on the second TSN domain information and the first correspondence, that the second TSN device and the first TSN device belong to a same TSN domain.

Abstract: A data transmission method and corresponding apparatus are provided. The method implemented by a terminal device includes: receiving indication information from a network device, where the indication information includes a bit sequence, a value of an ith bit in the bit sequence indicates a usage status of an ith logical channel in M logical channels associated with a radio bearer, and a duplication transmission function is configured for the radio bearer; transmitting data based on the indication information through at least one logical channel associated with the radio bearer. According to the application, the M logical channels are sorted based on IDs of cell groups associated with the M logical channels and IDs of the M logical channels, and the ith bit indicates the usage status of the ith logical channel, thereby enabling the terminal transmitting data via at least one logical channel associated with the radio bearer.
