Provided is a base station capable of SFN transmission of multicast data by using an empty section of an allocated resource. In this base station, an arrangement unit (109) arranges unicast data, multicast data, control information for downlink line unicast data, control information for uplink line unicast data, and a pilot for unicast data in one of sub-carriers in a plurality of OFDM symbols and outputs them to an IFFT unit (110). The IFFT unit (110) performs IFFT on a plurality of sub-carriers to generate an OFDM symbol. The arrangement unit (109) arranges control information for downlink line unicast data according to an arrangement pattern common to a plurality of cells in a sub-frame where unicast data is arranged and no multicast data is arranged and arranges multicast data according to the same arrangement pattern as the common arrangement pattern in a sub-frame where multicast data is arranged.
