Abstract: A base station according to a first aspect is used in a mobile communication system. The base station comprises: a transmitter configured to transmit, in an unlicensed band, a control signal and data by using a downlink subframe; and a controller configured to control transmission by the transmitter. The downlink subframe includes a PDCCH interval in which the control signal is arranged and a PDSCH interval in which the data is arranged. In the PDCCH interval, if there is an available region where the control signal is not arranged, the controller arranges a dummy signal in the available region.
