  • System and method for transmitting/receiving multicast/broadcast signal in a communication system
    Patent number: 8194578
    Abstract: A system and method for transmitting/receiving a multicast/broadcast signal in a communication system are provided, in which if the communication system includes at least one zone to which the same service is provided and the zone includes at least one ASN_GW and at least one BS connected to the ASN_GW, the ASN_GW generates a second multicast/broadcast signal using a received first multicast/broadcast signal according to information about the zone, generates time information indicating a time when the BS is to transmit the second multicast/broadcast signal, and transmits the second multicast/broadcast signal and the time information to the BS.
