Method and system for transmitting/receiving data in a communication system

A method for receiving data in a communication system, the method comprising:

• receiving, from a Base Station (BS) of a serving cell frame where a Mobile Station (MS) is currently located, a frame having a data transmission region that is divided into a first region and a second region;
• detecting information included in a preamble region and a MAP message region of the received frame, and determining a region where the MS is located depending on the detected information;
• and
• detecting data included in the first region if the MS that receives the data is located in a non-interference region, and detecting data included in the second region if the MS that receives the data is located in an interference region according to the determination result,
• wherein the second region divided from a data transmission region of a neighbor cell frame and the second region divided from a data transmission region of a serving cell frame have the same size and position, and
• wherein the second region divided from the data transmission region of the neighbor cell frame and the second region divided from the data transmission region of the serving cell frame are divided into a plurality of unit regions having the same size in a frequency domain and a time domain.

An apparatus for transmitting data by a Base Station (BS) in a communication system, the system comprising:

• a controller for determining, when data to be transmitted to at least one Mobile Station (MS) is generated, a region where an MS that receives the generated data among the at least one MS is located based on feedback information received by the at least one MS,
• a MAP and data allocator for allocating resources of a data transmission region divided into a first region and a second region to the MS that receives the data according to the determination result, including the generated data in a region where the resources are allocated, including, in a MAP message region, resource allocation information representing the region where the generated data is included and information on the MS that receives the data included in the resource-allocated region, and transmitting, to the MS, a frame including the region in which the generated data is included, and the MAP message region;
• and
• wherein the second region divided from the data transmission region of a neighbor cell frame and the second region divided from the data transmission region of a serving cell frame have the same size and position, and
• wherein the second region divided from the data transmission region of the neighbor cell frame and the second region divided from the data transmission region of the serving cell frame are divided into a plurality of unit regions having the same size in a frequency domain and a time domain.
