The present invention is designed so as to be able to preferably control the degradation of spectral efficiency even when communication is performed using a plurality of uplink control channel formats carrying different numbers of symbols. A user terminal according to one aspect of the present invention has a transmission section that transmits uplink control information using at least one of a plurality of uplink control channel structures carrying different numbers of symbols, and a control section that exerts control so that, regardless of which of the plurality of uplink control channel structures is used, a reference signal is mapped to a same time resource.
