Abstract: Disclosed is a relay method for relaying temporal-spatial block code scheme-based data using a plurality of relay terminals. An embodiment comprises the steps of: generating an effective interference channel matrix on the basis of interference channel matrixes between source terminals and destination terminals; calculating a basis matrix indicating a null space of the effective interference channel matrix; generating an effective channel matrix on the basis of channel matrixes between the source terminals and the destination terminals; and generating beamforming matrixes for relay terminals on the basis of the effective channel matrix and the basis matrix.

Abstract: Provided are a base station and a plurality of member nodes for transmitting and receiving network coding based multicast traffic. The base station may transmit multicast traffic, and the member node may transmit an acknowledgement (ACK) signal based on received multicast traffic. A determination made be made as to whether the multicast traffic is to be retransmitted, based on a number of member nodes transmitting ACK signals.

Abstract: A method of determining a pair of a target transmission node and a target reception node distributedly and concentratedly using a cooperation header in a multi-hop network performing interference neutralization, is provided. The method of distributedly determining the pair of the transmission node and the reception node includes determining whether any of other reception nodes broadcasts a pair configuration message to configure a pair between a corresponding one of the other reception nodes and the transmission node. The method further includes configuring the pair between the transmission node and the reception node based on the determination.

Abstract: A method and apparatus to manage interference between idle devices is provided. The method may include determining a pair of a target transmission node and a target reception node among nodes included in a multi-hop network. The method includes determining idle devices cooperating to manage interference in the communication based on a transmission mode determined for communication. The method determines and transmitting coordination information for communication between the pair of the target transmission node and the target reception node, to nodes participating in the communication and the cooperating idle devices.
