摘要： A frequency band is divided into N subchannels. Sub-channels are first allocated for a power line communication system having a higher priority, such as public communication or the like. Sub-channels for a power line communication system having a relatively low priority, such as in-home communication or the like, are allocated from free subchannels. In this case, the subchannels used by the power line communication system having the high priority are limited to a plurality of consecutive subchannels from an upper side or a lower side of the frequency band.

摘要： When operating as a control terminal and recognizing interference from another logical network, a terminal apparatus determines whether or not a logical network to be controlled is unified with the other logical network. When unification is determined, the terminal apparatus determines whether a control terminal of a logical network newly created by unification is the terminal apparatus or a control terminal of the other logical network.
