Abstract: Disclosed by the present application are a data transmission method, device and apparatus, the method comprising: a terminal transmitting data to a base station by means of normal resources; when the base station adjusts the configuration of the normal resources so that the terminal transmits data when the normal resources are unavailable, or when the normal resources cannot complete a configured number of repeated transmissions, data is transmitted to the base station on potential resources, wherein the normal resources and the potential resources are resources used for transmitting data which are semi-statically configured for the terminal by the base station; and when the normal resources are unavailable and the potential resources do not serve as a third type of resource for other terminals, the base station and the terminal determine a potential resource for transmitting data that needs to be used according to the same mode.
