    • PURPOSE: A communication method of relay nodes and destination nodes for interference neutralization arranged in an interference channel is provided to utilize channel compatibility based on information for an arrangement space which is shared by a first source node and a second source node, thereby reducing channel feedback between the source node and a relay node. CONSTITUTION: A first relay node receives streams from first and second source nodes(510). The first relay node transmits a signal which an X stream, a Y stream, and a Z stream are arranged to first and second destination nodes(520). The first relay node calculates a transmission beam forming vector of the first source node which is used for transmission of the Y stream based on a vector which shows the same space(530). The first relay node calculates a transmission beam forming vector of the second source node which is used for transmission of the Z stream based on the vector(540). [Reference numerals] (510) Receive streams from a first source node and a second source node; (520) Transmit a signal which an X stream, a Y stream, and a Z stream are arranged to a first destination node and a second destination node; (530) Calculate a transmission beam forming vector of the first source node; (540) Calculate the transmission beam forming vector of the second source node; (AA) Start; (BB) End
    • 目的:提供一种布置在干扰信道中的中继节点和干扰中和目的节点的通信方法,以便利用第一源节点和第二源节点共享的布置空间信息的信道兼容性,从而减少信道反馈 在源节点和中继节点之间。 构成:第一中继节点从第一和第二源节点(510)接收流。 第一中继节点发送X流,Y流和Z流被布置到第一和第二目的地节点(520)的信号。 第一中继节点基于显示相同空间的向量计算用于Y流的传输的第一源节点的传输波束形成向量(530)。 第一中继节点基于向量计算用于Z流的传输的第二源节点的传输波束形成向量(540)。 (附图标记)(510)从第一源节点和第二源节点接收流; (520)将X流,Y流和Z流的信号发送到第一目的地节点和第二目的地节点; (530)计算第一源节点的传输波束形成向量; (540)计算第二源节点的传输波束形成矢量; (AA)开始; (BB)结束
