    • A transmitting apparatus which transmits a transmit symbol in orthogonal-frequency division multiplexing (OFDM) is disclosed. The transmitting apparatus includes a unit which provides a unicast channel; a unit which provides a multimedia broadcast multicast service (MBMS) channel; a unit which provides a specific pilot channel which is specific to a specified cell; a unit which provides one or more common pilot channels common to a plurality of cells; and a multiplexing unit which multiplexes the unicast channel, the MBMS channel, the specific pilot channel, and the one or more common pilot channels, and creates the transmit symbol, wherein the multiplexing unit time-division multiplexes, in the same frequency band, a unicast frame which includes the unicast channel, and an MBMS frame which includes the MBMS channel, and wherein an insertion density of the common pilot channel included in the MBMS frame is larger than an insertion density of the specific pilot channel included in the unicast frame.
    • 公开了一种在正交频分复用(OFDM)中发送发送符号的发送装置。 发送装置包括提供单播信道的单元; 提供多媒体广播多播服务(MBMS)信道的单元; 提供特定于特定小区的特定导频信道的单元; 提供一个或多个公共导频信道对于多个小区共同的单元; 以及复用单元,其对所述单播信道,所述MBMS信道,所述特定导频信道以及所述一个以上的公共导频信道进行复用,并且生成所述发送符号,其中,所述复用单元对相同频带进行时分复用, 包括单播信道的单播帧和包括MBMS信道的MBMS帧,并且其中包括在MBMS帧中的公共导频信道的插入密度大于包括在单播帧中的特定导频信道的插入密度。
