<P>PROBLEM TO BE SOLVED: To provide an interference determination method capable of determining presence or absence of interference appropriately in wireless communication between two communication devices, and to provide a communication device and a communication system. <P>SOLUTION: When transmitting a wireless signal from a transmission node to a reception node, the reception node determines presence or absence of interference, as follows, by an interference determination method. At first, the distance between the transmission node and the reception node is estimated. Subsequently, the reference value of reception power of a signal to be received from the transmission node is calculated by the distance thus estimated. The reception power of a signal thus received is compared with the reference value, and presence or absence of interference is determined based on the comparison results. <P>COPYRIGHT: (C)2012,JPO&INPIT |
