<p>This slave node receives a synchronization frame transmitted by this master node, thereby initializing a timer of the slave node. The slave node then transmits a transmission received frame to the master node. The master node receives the transmission received frame transmitted by the slave node, and from the difference between the timer time at reception and the timer time when the synchronization frame that was transmitted from the slave node, the master node calculates the round-trip transmission delay time between the master node and the slave node, and transmits a round-trip transmission delay time notification frame notifying the slave node of the calculated round-trip transmission delay time. The slave node receives the round-trip transmission delay time notification frame, and on the basis of the round-trip transmission delay time included in the notification frame, synchronizes the slave node timer with the master node timer.</p> |
