Patent ID: 8681678

Claim:
A multicast and broadcast service (MBS) data transmission method for use in a multicast broadcast single frequency network (MBSFN) zone, the method comprising: constructing a resource region in a downlink subframe for transmitting the MBS data by sequentially allocating predetermined resource blocks to the resource region according to a frequency axis and a time axis; dividing the MBS data into one or more segments which has the size of a predetermined resource block; mapping the divided MBS data to each of the resource blocks of the resource region; and transmitting a first MBS data among the mapped MBS data to mobile stations located at an edge of the MBSFN zone, when a mobile station is within a common area between an edge of the MBSFN zone and an edge of a neighbor MBSFN zone, wherein the resource blocks are sequentially allocated to the resource region according to the frequency axis, and then are repeatedly allocated to the resource region according to the time axis, wherein a second MBS data, which is among MBS data provided from the neighbor MBSFN zone, and the first MBS data are the same, wherein the first MBS data and the second MBS data are transmitted to the same time zone according to a time division multiplexing (TDM) method by using a same method for allocating the resource region, and wherein the divided MBS data are mapped to the resource region using a symbol offset value and predetermined consecutive resource blocks.
