摘要： A terminal that communicates with a base station monitors a physical downlink control channel allocated in a physical downlink control channel region and an enhanced physical downlink control channel allocated in a physical downlink shared channel region different from the physical downlink control channel region. If the physical downlink control channel is detected, the terminal reports response information via a physical uplink control channel resource corresponding to the resource in which the physical downlink control channel was detected. If the enhanced physical downlink control channel is detected, the terminal reports via a prescribed physical uplink control channel resource.
