Abstract: Data transmitting and receiving apparatus and method for control intercell interference efficiently in a mobile communication system. A mobile communication system includes distributed small base stations including a super node and two or more general nodes. Each of the general nodes processes and transmits first data for transmission, and outputs second data independent of the first data to the super node. The super node receives the second data from the respective general nodes, and processes and transmits the second data and third data for transmission.

Abstract: A method for operating a base station in a wireless communication system is provided. In the method, feedback is received from at least one terminal. When the base station configures terminal allocation information, a terminal that the base station is to service is determined based on information included in the feedback. A combination of base stations allowing the determined terminal to obtain maximal performance is determined with consideration of the information included in the feedback and a gain of cooperation between base stations.

Abstract: An apparatus and a method relieve intercell interference in a wireless communication system. In a method for operating a transmission node, a first private message encoding a portion of transmission data of a neighbor transmission node is received. Weight for canceling the first private message of the neighbor transmission node received in a intended reception node is determined. The first private message of the neighbor transmission node multiplied by the weight, a common message encoding a portion of data to be transmitted to the intended reception node, and a second private message encoding the rest of the data are transmitted.
