Provided are a signal retransmitting method and an apparatus thereof. In a network environment where at least two pairs of nodes exist and signals are transmitted and received between each pair of nodes, a transmission node receives feedback information including acknowledgment/non-acknowledgment (ACK/NACK) for initial transmission from an interference node and its own reception node. The transmission node performs signal retransmission by considering both the feedback information of its own reception node and the feedback information of the interference node. Accordingly, the present invention can improve a transmission success rate and efficiently retransmit the signals.
