Method and apparatus for transmitting data in a wireless communication system

A data transmission method in a wireless communication system, the method comprising:

• dividing, by at least one base station, a multicast broadcast single frequency network MBSFN zone including a plurality of cells into at least one sub-zone including at least one cell,
• wherein the at least one sub-zone is configured only with all edge cells of the plurality of cells included in the MBSFN zone;
• transmitting first multicast broadcast service (MBS) data through the plurality of cells belonging to the MBSFN zone;
• and
• transmitting second MBS data through the all edge cells belonging to the at least one sub-zone transmitted,
• wherein the second MBS data is retransmission data of the first MBS data only if the at least one sub-zone is configured with all edge cells in the MBSFN zone.
