A terminal is disclosed including a processor that controls a transmission of an uplink control information using a cyclic shift that is based on the uplink control information, the uplink control information including a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK), and a transmitter that transmits the uplink control information in an uplink control channel, wherein intervals between two cyclic shifts that are respectively based on two values of a 1-bit HARQ-ACK are each equal to π, and intervals between four cyclic shifts that are respectively based on four values of a 2-bit HARQ-ACK are each equal to π/2. In other aspects, a radio communication method for a user terminal is also disclosed.
