METHOD AND APPARATUS FOR TRANSMITTING MULTICAST DATA IN BROADBAND WIRELESS COMMUNICATION SYSTEMS

摘要

PURPOSE: A method and an apparatus for transmitting multicast data in a broadband wireless communication system are provided to efficiently transmit multicast data to all terminals. CONSTITUTION: A receiver receives multicast data from a source terminal. The multicast data includes a multicast IP address. The multicast IP address is used on a network layer. A controller(511) includes the multicast IP address in the control message of a MAC layer. The controller transmits the multicast data to the terminal.
