Claim 2:
3. A system comprising:
a terminal that comprises:
a processor that determines to use, in a same slot, both of a first uplink control channel with one symbol or two symbols and a second uplink control channel that is transmitted in a longer period than two symbols, based on information to indicate that uplink control information (UCI) includes channel state information (CSI), the information being configured by radio resource control (RRC) signaling; and
a transmitter that transmits the UCI using the determined uplink control channel in the same slot,
wherein a number of symbols in the same slot is fourteen,
a format of the first uplink control channel is different from a format of the second uplink control channel,
the first uplink control channel does not overlap with the second uplink control channel, and
when both the first uplink control channel and the second uplink control channel are determined to be used in the same slot, the transmitter transmits different UCI over the first uplink control channel and the second uplink control channel, and

a base station that comprises:
a receiver that receives the UCI that is transmitted using the determined uplink control channel in the same slot.
