Abstract

A user terminal according to a first aspect is used in a mobile communication system. The user terminal comprises: a receiver configured to receive, from a base station, candidate timing information indicating candidate timings of an uplink transmission on an unlicensed band channel that is a frequency channel of an unlicensed band; a controller configured to determine, by monitoring the unlicensed band channel, a transmission timing at which the uplink transmission to the base station is performed, from the candidate timings indicated by the candidate timing information; and a transmitter configured to transmit, at the transmission timing, uplink data via the unlicensed band channel to the base station.
