Patent ID: 7826337

Claim:
A communication node for relaying a signal between a source node and a destination node, the communication node being used as a first relay node in a system which includes the first relay node, a second relay node, the source node and the destination node, the communication node comprising: a relay signal generation unit configured to generate a transmit signal by reducing, from a receive signal, an interference signal received from the second relay node and by performing a process such that the transmit signal is not received as an interference signal by the second relay node, wherein the first relay node receives a first transmit signal from the source node in a first time slot, and the second relay node transmits a first relay signal to the destination node in the first time slot, and the second relay node receives a second transmit signal from the source node in a second time slot, which is the next time slot relative to the first time slot, and the first relay node transmits a second relay signal generated based on the first transmit signal to the destination node in the second time slot.
