Abstract
A user terminal according to an embodiment comprises a receiver; and a controller. The receiver receives, from a base station, a message including first and second information. The first information is information regarding to a configuration for reporting a power measured by the user terminal in the unlicensed band, and includes period information indicating a period of a measurement in the unlicensed band. The second information is information regarding to a configuration of carrier aggregation. The controller periodically measures the power in the unlicensed band according to the period information; reports to the base station on information classified according to the measured power as information indicating the measured power, based on the first information; performs a configuration for using the unlicensed band as a secondary carrier in the carrier aggregation, based on the second information; and communicates a communication with the base station by using the secondary carrier.
