This user terminal, located within a first cell that is operated at a first frequency as part of a mobile communication system that supports D2D proximity services, is provided with a transmission unit that, using a radio resource at a second frequency that is different from the first frequency, transmits a discovery signal for discovering nearby terminals located within a second cell that is different from the first cell. The aforementioned radio resource at the second frequency is used exclusively for uplink purposes. |
