Abstract
Provided is a method for mitigating, by an interference mitigation apparatus, interference on a home network transmission line. The method includes pairing domain masters with relay terminals by a signal having a unique frequency, grouping the domain masters, performing Tx/Rx synchronization between the domain masters and the relay terminals, and controlling the domain masters and the relay terminals to transmit/receive data according to the Tx/Rx synchronization. The domain masters of the same groups may be controlled not to simultaneously transmit/receive data.
Claims16
A method for mitigating, by an interference mitigation apparatus, interference on a home network transmission line, the method comprising:
- pairing domain masters with relay terminals by a signal having a unique frequency;
- grouping the domain masters;
- performing Tx/Rx synchronization between the domain masters and the relay terminals;
- and
- controlling the domain masters and the relay terminals to transmit and receive data according to the Tx/Rx synchronization,
- wherein the controlling comprises controlling the domain masters of a same groups not to simultaneously transmit/receive data.
An apparatus for interference mitigation comprising:
- a pairing unit configured to pair domain masters with relay terminals by transmitting/receiving a signal with a unique frequency;
- a control unit configured to group the domain masters using status information of channels and to control the grouped domain masters to transmit/receive data,
- wherein the control unit includes a grouping unit configured to group the domain masters causing interference and a synchronizing unit configured to perform Tx/Rx synchronization between the domain master and the relay terminal, which are paired, and
- wherein the control unit is configured to control the domain masters and the relay terminals to transmit/receive data according to the Tx/Rx synchronization and to control the grouped domain masters not to simultaneously transmit/receive data.
A communication system comprising:
- two or more relay terminals paired with domain masters and connected to the paired domain masters via transmission lines;
- an interference mitigation apparatus configured to register the relay terminals paired with the domain masters and synchronize the domain masters to transmit/receive data;
- and
- a server configured to calculate interference data of channels based on a channel status of each port of a respective one of the domain masters and provide the calculated the interference data to the interference mitigation apparatus to synchronize the domain masters.
