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.

transmitting coordination information to nodes that are participating in the communication and the idle devices for the communication between the target transmission node and the target reception node,
receiving channel information from the idle devices through a first communication network;
determining amplifying coefficients to manage the interference based on the channel information; and
transmitting the amplifying coefficients to the idle devices.

2. The method of claim 1 , wherein the determining of the transmission mode comprises:
determining the transmission mode based on a channel capacity of the first communication network and a channel capacity of the second communication network.

3. The method of claim 1 , wherein the determining of the idle devices comprises:
determining the idle devices cooperating to manage interference in the communication among idle devices connected through the second communication network in response to the transmission mode being the second transmission mode that uses the second communication network.

4. The method of claim 1 , further comprising:
identifying the nodes in the multi-hop network and the idle devices.

5. The method of claim 1 , wherein the coordination information comprises at least one of an indicator informing the target transmission node, the target reception node, and the idle devices of participation in the communication and an indicator informing the target transmission node, the target reception node, and the cooperating idle devices of the communication using the second communication network.

6. The method of claim 1 , wherein the first communication network uses a different communication method from a communication method of the second communication network.

7. The method of claim 1 , wherein the first communication network and the second communication network use wireless resources orthogonal to each other when the first communication network and the second communication network use a same communication method.

8. The method of claim 1 , wherein the target transmission node and the target reception node in the multi-hop network, and the cooperating idle devices communicate with one another using the second communication network.

9. A non-transitory computer readable recording medium storing a program to cause a computer to execute the method of claim 1 .
