Patent ID: 8750193

Claim:
A method of transmitting multicast broadcast service (MBS) data in an MBS transmitting apparatus, the method comprising: allocating subbands of an MBS transmission carrier to an MBS region and a non-MBS region; generating region allocation information of the MBS region and the non-MBS region; allocating subbands, allocated to the MBS region, to at least one MBS zone; generating MBS zone allocation information of the at least one MBS zone; transmitting the region allocation information and the MBS zone allocation information; transmitting the MBS data through the subbands allocated to the MBS region; generating multi-input multi-output (MIMO) region allocation information for the MIMO region; and transmitting the MIMO region allocation information to an MBS receiving apparatus, wherein the region allocation information indicates whether each subband is allocated to the MBS region or allocated to the non-MBS region, the region allocation information is broadcast through a system information message, the MBS zone allocation information is broadcast through an MBS-specific message, the MIMO region allocation information is broadcast through the system information message, the MBS transmission carrier corresponds to an MBS dedicated carrier, the non-MBS region corresponds to an unused region, the dedicated carrier is temporally divided for every superframe, the dedicated carrier is divided into a plurality of subbands on a frequency axis, the MBS region is divided into multiple MBS zones on the frequency axis, and an MBS map is transmitted at the beginning of an MBS scheduling interval.
