Abstract:
A terminal is disclosed including a transmitter that transmits uplink control information including a Hybrid Automatic Repeat reQuest-ACKnowledge (HARQ-ACK) in an uplink control channel; and a processor that uses a cyclic shift in the transmission of the uplink control information, the cyclic shift being determined based on a sum of an index and a value mapped to the uplink control information, wherein a value mapped to first uplink control information including HARQ-ACK information and a negative Scheduling Request (SR) is equal to a value mapped to second uplink control information including the HARQ-ACK information and not including a positive SR or the negative SR. In other aspects, a radio control method and a base station are also disclosed.
