An embodiment of the present invention provides a method, UE and base station for data transmission. The method comprises: User Equipment (UE) determining that spectrum resources of an unauthorized cell are not available; and the UE communicating with the unauthorized cell by means of an authorized cell. On the basis of the embodiment of the present invention, the UE and the unauthorized cell can communicate with each other by means of the authorized cell when the spectrum resources of the unauthorized cell are not available, thereby reducing the impact on the data transmission when the spectrum resources of the unauthorized cell are not available, increasing a data transmission rate, improving spectrum utilization, and reducing waste of resources.
