Abstract: The present application discloses a resource selection method, a data transmission method and a device, relating to the field of communication technology. In the embodiment of the present application, in a case where it is determined that the resource multiplexing mode of the first link and the second link is frequency division multiplexing, by judging whether the selected link is allowed to select a resource that overlaps with the selected resource on another link in the time domain, it may further determine whether to select a resource that does not overlap with the selected resource on another link in the time domain to transmit a service packet to be sent, such that it can also be adjusted according to actual needs based on the pre-configuration, thereby greatly increasing the flexibility of resource selection and the efficiency of spectrum use.
