1. A base station, comprising:
a transmitter, which, in operation, transmits, to a terminal, downlink control information, and transmits, to the terminal, a plurality of downlink data on a plurality of component carriers, respectively; and
a receiver, which, in operation, receives uplink control information that includes a response signal for the plurality of downlink data, that is transmitted from the terminal, wherein:
the response signal represents a combination of one or more of an Acknowledgement (ACK), a Negative Acknowledgment (NACK), and a Discontinuous Transmission (DTX) as outcomes of decoding of the plurality of downlink data,
wherein when the uplink control information includes only the response signal for the plurality of downlink data, the receiver, in operation, receives the uplink control information including a symbol on an uplink control channel resource that are both selected by the terminal, based on the combination, from a plurality of symbols and a plurality of uplink control channel resources, respectively, that are assigned to the response signal,
wherein a first symbol of the uplink control information and a first uplink control channel resource are selected by the terminal, based on the combination, to represent a three-outcome combination including a NACK for third downlink data of the plurality of downlink data and an outcome other than an ACK for first and second downlink data of the plurality of downlink data irrespective of whether the outcome is DTX or NACK,
wherein the first symbol of the uplink control information and a second uplink control channel resource, different from the first uplink control channel resource, are selected by the terminal, based on the combination, to represent a three-outcome combination including DTX for the third downlink data of the plurality of downlink data, a NACK for the second downlink data and an outcome other than an ACK for the first downlink data of the plurality of downlink data irrespective of whether the outcome is DTX or NACK, wherein the first symbol represents a maximum of four states,
wherein when the uplink control information includes both the response signal for the plurality of downlink data and a scheduling request (SR), the receiver, in operation, receives the uplink control information on an uplink control channel resource that is assigned to the SR and is identified regardless of the combination.
