The present invention is designed to reduce the degradation of communication quality even when future radio communication systems support UL control channels of different formats than existing systems. A transmission section that allocates uplink control information and an uplink reference signal to different frequency resources in an uplink control channel allocation field, and transmits the uplink control information and the uplink reference signal, and a control section that controls the allocation of the uplink control information and the uplink reference signal are provided, and the control section makes the frequency resources where the uplink reference signal is allocated hop between different time fields and/or between different resource blocks.
