The present invention is designed so that communication can be carried out adequately even when the bandwidth to use is limited to partial reduced bandwidths in a system bandwidth. According to an example of the present invention, a user terminal, in which the bandwidth to use is limited to a partial reduced bandwidth in a system bandwidth, has an acquiring section that acquires EPDCCH (Enhanced PDCCH) configuration information based on information that is reported from a radio base station without using a PDCCH (Physical Downlink Control Channel), and a receiving section that detects a user terminal-specific search space (USS: UE-specific Search Space) of an EPDCCH based on the EPDCCH configuration information.
