There are provided a base station, a terminal, a communications system, and a communications method which enable efficient transmission and reception of transmission data even in the case where the base station notifies the terminal of control information via an enhanced physical downlink control channel.;A terminal configured to perform communication with a base station monitors a physical downlink control channel mapped to a physical downlink control channel region, and acquires higher-layer control information indicating a plurality of enhanced physical downlink control channel regions different from the physical downlink control channel region. In the case where the terminal has acquired the higher-layer control information, the terminal monitors an enhanced physical downlink control channel mapped to at least one region from among the plurality of enhanced physical downlink control channel regions, in place of the physical downlink control channel mapped to the physical downlink control channel region. |
