Claim:
1. A method for operating a transmission node in a wireless communication system, the method comprising: encoding a portion of data to be transmitted to an intended reception node as a first common message; encoding a remaining portion of the data to be transmitted to the intended reception node as a first private message; receiving a second private message encoding a portion of transmission data of a neighbor transmission node, wherein a remaining portion of the transmission data of the neighbor transmission node is encoded, by the neighbor transmission node, as a second common message; determining a weight for canceling the second private message of the neighbor transmission node received in the intended reception node; transmitting the second private message of the neighbor transmission node multiplied by the weight, the first common message, and the first private message, wherein the first common message and the second common message are decodable by other reception nodes and the intended reception node, and the first private message is decodable by the intended reception node, wherein the second common message is transmitted, by the neighbor transmission node, to the intended reception node and decoded by the intended reception node.
