Abstract
In order to minimize reduction of the usage efficiency of radio resources even when a radio base station performs LBT in an LTE/LTE-A operating system, the present invention provides a user terminal capable of communicating with a radio base station of a given operator using an unlicensed band. The user terminal has: an obtaining section that obtains a PLMN-ID (Public Land Mobile Network Identifier) of a cell that is detected in a cell search; a detecting section that detects the cell of an other operator cell that is different from the given operator based on the PLMN-ID; and a transmission section that transmits an identifier to specify the cell of the other operator and the PLMN-ID of the other operator to the radio base station.
