Method for determining pair of target receiver and target transmitter distributedly and concentratedly using cooperation header in a multi-hop network performing interference neutralization
First Claim
1. A method of distributedly determining a pair of a transmission node and a reception node in a multi-hop network performing interference neutralization, the method comprising:
- calculating a metric between the transmission node and the reception node;
setting a standby time based on the metric;
determining, according to the standby time, whether another reception node in the multi-hop network broadcasts a pair configuration message to configure a pair between the other reception node and the transmission node;
broadcasting, by the reception node, a pair configuration message to the other reception node and the transmission node to configure the pair between the transmission node and the reception node, in response to determining that the other reception node does not broadcast a pair configuration message to configure the pair between the transmission node and the other reception node; and
recognizing a pair configuration between the other reception node and the transmission node, in response to determining that the other reception node broadcasts the pair configuration message to configure the pair between the transmission node and the reception node.

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.

10. An apparatus for distributedly determining a pair of a transmission node and a reception node in a multi-hop network performing interference neutralization, the apparatus comprising:
-
a reception node configured to calculate a metric between the transmission node and the reception node; set a standby time based on the metric; determine, according to the standby time, whether another reception node in the multi-hop network broadcasts a pair configuration message to configure a pair between the other reception node and the transmission node; broadcast, by the reception node, a pair configuration message to the other reception node and the transmission node to configure the pair between the transmission node and the reception node, in response to determining that the other reception node does not broadcast a pair configuration message to configure the pair between the transmission node and the other reception node; and recognize a pair configuration between the other reception node and the transmission node, in response to determining that the other reception node broadcasts a pair configuration message to configure the pair between the transmission node and the other reception node. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
