ABSTRACT:
In-home communication systems110and130and an access communication system120that are capable of co-existing. The communication systems110and130and the access communication system120are able to co-exist by utilizing TDM that is in synchronization with a power cycle. Further, communication system that needs to secure AV-QoS assigns transmission timing to a slave station within itself by synchronizing a beacon cycle with a cycle of a power line.
