摘要：A transmitting apparatus which transmits a transmit symbol in orthogonal-frequency division multiplexing (OFDM) is disclosed. The transmitting apparatus includesa unit which provides a unicast channel; a unit which provides a multimedia broadcastmulticast service (MBMS) channel; a unit which provides a specific pilot channel which isspecific to a specified cell; a unit which provides one or more common pilot channelscommon to a plurality of cells; and a multiplexing unit which multiplexes the unicastchannel, the MBMS channel, the specific pilot channel, and the one or more common pilotchannels, and creates the transmit symbol, wherein the multiplexing unit time-divisionmultiplexes, in the same frequency band, a unicast frame which includes the unicastchannel, and an MBMS frame which includes the MBMS channel, and wherein an insertiondensity of the common pilot channel included in the MBMS frame is larger than aninsertion density of the specific pilot channel included in the unicast frame.
