Abstract
Among plural communications nodes that transfer data to a communications apparatus by multihop communication, a communications node includes a transmitting circuit configured to transmit a synchronization request signal requesting transmission of a synchronization signal for synchronizing the multihop communication at the communications node; a receiving circuit configured to receive the synchronization signal in response to the synchronization request signal transmitted by the transmitting circuit; and a power control circuit configured to control the receiving circuit such that a state of the receiving circuit is a first state where power consumption of the receiving circuit is a first power before the transmitting circuit transmits the synchronization request signal and is a second state where the power consumption of the receiving circuit is a second power that is higher than the first power after the transmitting circuit transmits the synchronization request signal.
