Abstract: Embodiments of the present invention provide a data transmission method and device. The method includes: when a resource position of a first data packet is preempted, generating, by a first device, first indication information, where the first indication information is used to indicate information about the preempted resource position of the first data packet; and sending, by the first device, the first indication information to a second device, so that the second device receives the first data packet based on the first indication information.
