Fuente: Wipo "IOT" One disclosure of the present specification provides a method in which a UE performs communication. The method comprises steps in which an A-IoT intermediate node: transmits information about an A-IoT signal to a base station, the A-IoT signal being a signal that activates an A-IoT device for an A-IoT operation, and the information about the A-IoT signal including information about a candidate frequency of the A-IoT signal; receives activation information from the base station on the basis of the information about the A-IoT signal, the activation information including information about a frequency that can be used for the A-IoT signal; and transmits the A-IoT signal to the A-IoT device on the basis of the activation information.
