Abstract
A method and system of a relay node managing interference in a multi-hop network and a relay node that manages interference is provided. The relay node may determine whether an interference neutralization condition for neutralizing interference among pairs of transmitting nodes and receiving nodes is satisfied, select one of a full interference neutralization and a partial interference neutralization, based on a result of the determination and perform the selected interference neutralization with respect to the pairs of the transmitting nodes and the receiving nodes.
Claims20
A method of a relay node managing interference in a multi-hop network, the method comprising:
- determining, by comparing a number of relay nodes included in the network to a value calculated based on a number of pairs of transmitting nodes and receiving nodes included in the network, whether an interference neutralization condition to neutralize interference among the pairs of transmitting nodes and receiving nodes is satisfied;
- selecting one of a full interference neutralization and a partial interference neutralization based on a result of the determination;
- and
- performing the selected interference neutralization with respect to the pairs of transmitting nodes and receiving nodes.
A relay node for managing interference in a multi-hop network, the relay node comprising:
- a processor configured to control one or more processor-executable units;
- a determining unit configured to determine, by comparing a number of relay nodes included in the network to a value calculated based on a number of pairs of transmitting nodes and receiving nodes included in the network, whether an interference neutralization condition for neutralizing interference among the pairs of transmitting nodes and receiving nodes is satisfied;
- a selecting unit configured to select one of a full interference neutralization and a partial interference neutralization, based on a result of the determination;
- and
- a performing unit configured to perform the selected interference neutralization with respect to the pairs of transmitting nodes and receiving nodes.
A terminal including at least one of a transmitting node and a receiving node, the at least one of the transmitting node and receiving node being configured to transmit a signal to a relay node in a multi-hop network, the relay node comprising:
- a determining unit to determine, by comparing a number of relay nodes included in the network to a value calculated based on a number of pairs of transmitting nodes and receiving nodes included in the network whether an interference neutralization condition for neutralizing interference among the pairs of transmitting nodes and receiving nodes is satisfied;
- a selecting unit to select one of a full interference neutralization and a partial interference neutralization, based on a result of the determination;
- and
- a performing unit to perform the selected interference neutralization with respect to the pairs of transmitting nodes and receiving nodes.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a computer, cause the computer to perform a method of a relay node managing interference in a multi-hop network, the method comprising:
- determining, by comparing a number of relay nodes included in the network to a value calculated based on a number of pairs of transmitting nodes and receiving nodes included in the network, whether an interference neutralization condition to neutralize interference among the pairs of transmitting nodes and receiving nodes is satisfied;
- selecting one of a full interference neutralization and a partial interference neutralization based on a result of the determination;
- and
- performing the selected interference neutralization with respect to the pairs of transmitting nodes and receiving nodes.
