A cooperative retransmission scheme in high dense networks

In this paper, we propose a cooperative retransmission scheme in a high dense network. The propose scheme applies a close-loop MIMO scheme for the retransmission. And, we consider the property of which the interference node is similar between the initial transmission and the retransmission. Then the transmitted node can retransmit the precoded signal considering interference for multiple pair nodes. The performance evaluation shows that the proposed scheme results in the performance gain from the point of view of the success probability of data detection in spite of the increase of feedback messages.
