The present invention is designed to transmit UCI adequately even when the formats of multiple UL control channels having different durations are made simple and/or common. A user terminal, according to the present invention, has a transmission section that transmits uplink control information (UCI) by using an uplink (UL) control channel, which has a first duration, or a UL control channel, which contains a plurality of units each constituted by the UL control channel of the first duration, and which has a second duration, and a control section that controls arrangement of a reference signal which is at least time-division-multiplexed with the UCI, and the ratio of the number of symbols in which the reference signal is arranged, to the number of all the symbols in the first duration, is 1/2 or less.
