Broadcast service data transmission/reception method and the system in the radio communication system

摘要

This invention rises inside one frame and offers the method and the system in order to transmit the broadcast service data the crossing frequency division multiplex connection which transmits the data through link and descent link (OFDMA) in the radio communication system which uses system. The aforementioned system is connected to the broadcast server. The aforementioned system and method, through the aforementioned descent link, the connected identifier (CID) allot to each broadcast service for identifying the broadcast service packet which is transmitted receive the broadcast packet from step, and the aforementioned broadcast server who transmit the information of broadcast service for each broadcast service the physical hierarchical transmission information element which includes the broadcast service CID for the aforementioned broadcast packet (DL-MAP) through the aforementioned descent link, include with the step which transmits.
