There are provided a user terminal, a radio base station, and a radio communication method in which a wake-up signal (WUS) is capable of being suitably introduced under the presence of multiple user terminals. The user terminal includes a reception section which receives a wake-up signal, and a control section which detects an identifier associated with the wake-up signal and controls, based on the detected identifier, reception of a control signal associated with the wake-up signal. The number of the wake-up signals is smaller than a number relating to a terminal group.
