Method for transmitting and receiving broadcast service data in an OFDMA wireless communication system

摘要

A method for providing two or more broadcast services in an orthogonal frequency division multiple access (OFDMA) wireless communication system. The method comprises the steps of separately receiving broadcast services to be transmitted, and independently performing coding, interleaving and modulation on the broadcast services according to a required quality for each of the broadcast services; segmenting each of the modulated broadcast signals into minimum transmission units; time-division-multiplexing the segmented broadcast service signals; configuring a frame comprising information on the broadcast service in physical layer transmission information transmitted together with the broadcast service; and transmitting the frame.
