Abstract:
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 enhanced 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 enhanced physical downlink control channel was detected.
