1. An operating method of a Base Station (BS) for interference cancellation in a wireless communication system, the method comprising the steps of:

  • gathering resource allocation information relating to an Interference Cancellation (IC) zone of neighbor cells, when a resource of the IC zone is allocated to a terminal traveling in a coverage, wherein the IC zone has a fixed Modulation and Coding Scheme (MCS) format,generating resource allocation information relating to the resource of the IC zone allocated to the terminal, wherein the resource allocation information comprises a bit map that includes information indicating whether the neighbor cells use a same resource as the resource allocated to the terminal; and

    transmitting the resource allocation information relating to the resource of the IC zone allocated to the terminal, to the terminal,wherein generating resource allocation information comprises;

    determining whether a neighbor cell exists that uses the same resource as the resource allocated to the terminal using the resource allocation information of the IC zone of the neighbor cells;

    constituting information relating to whether the neighbor cells use the same resource as the resource allocated to the terminal, as a bit map; and

    generating resource allocation information relating to the resource of the IC zone allocated to the terminal comprising the bit map,wherein the bit map comprises information relating to whether every cell adjacent to the BS or one or more neighbor cells selected based on a receive signal strength among the neighbor cells use the same resource as the resource allocated to the terminal.
