Abstract
The present invention is designed so that the decrease of spectral efficiency can be reduced even when coverage enhancement is attempted in communication by user terminals in which the bandwidth to use is limited to partial reduced bandwidths in a system bandwidth. A radio base station communicates with a user terminal in which the bandwidth to use is limited to partial reduced bandwidths in a system bandwidth, and this radio base station has a transmission section that transmits a downlink signal to the user terminal in repetitions, and a control section that controls transmission by applying a transmission method to use frequency hopping or a transmission method to use frequency scheduling to the downlink signal, and the transmission section transmits information about the transmission method to apply to the downlink signal to the user terminal.
