Abstract
The present invention is designed to optimize the uplink access procedure even when the band to use is limited to partial narrow bands in a system band. A user terminal, in which the band to use is limited to a partial narrow band in a system band, has a receiving section that receives system information that includes indication information of an uplink carrier frequency, from a radio base station, as system information for narrow bands, which is different from system information for the system band, and a transmission section that transmits a random access preamble to the radio base station in one of a plurality of narrow bands that are specified by the indication information of the uplink carrier frequency.
