Abstract:
A communication apparatus communicates with another communication apparatus connected to a transmission channel and sharing a communication band. The communication apparatus includes: a receiving unit that receives, through the transmission channel, data including time information based on a transmission time when a synchronous signal is transmitted to the transmission channel from a synchronous signal transmitting apparatus at a given cycle, the synchronous signal for synchronizing a plurality of communication apparatuses; a transmitting unit that transmits data to the transmission channel; and a transmission control unit that estimates a synchronous signal non-existing period in which there is no synchronous signal on the transmission channel on the basis of the time information received by the receiving unit and the given cycle, and controls the transmitting unit to transmit data within the estimated synchronous signal non-existing period.
