Original Abstract Submitted
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.
