Abstract: A communication apparatus has a receiver and a decoder. The receiver receives a control signal including first downlink control information and second downlink control information, and receives decoding area information that indicates whether the extended Physical Downlink Control Channel (PDCCH) should be decoded for each of a plurality of terminal apparatuses. The decoder decodes each of a plurality of first mapping candidates in the PDCCH area or decodes each of the plurality of first mapping candidates in the PDCCH area and each of the plurality of second mapping candidates in the extended PDCCH. A number of the second mapping candidates included in the user-specific search space equals to or is more than a number of the first mapping candidates included in the common search space.
