Abstract: A terminal is disclosed that includes a processor that determines a cyclic shift to be applied to a demodulation reference signal, based on a plurality of candidates configured by higher layer signaling and based on a field, for indicating a physical uplink control channel (PUCCH) resource for an uplink control information (UCI), included in a downlink control information. The terminal further includes a transmitter that transmits the UCI using a PUCCH format, in which the determined cyclic shift is applied to the demodulation reference signal and to which an orthogonal code having a sequence length less than 5 is applied, where the processor controls a frequency-domain orthogonal cover code (freq-domain OCC) to be applied for the PUCCH format, and where a number of bits of the UCI is more than 2. In other aspects, a base station and another terminal are also disclosed.
