Communication apparatus, communication system and communication method

A communication system comprising a slave station and a plurality of communication apparatuses capable of controlling the slave station, wherein

• a first communication apparatus that is one of the communication apparatuses comprises:
• a controller to acquire slave station information including information indicating a slave station controlled by a second communication apparatus other than the first communication apparatus among the communication apparatuses, to obtain, as a controlled slave station, the slave station that does not overlap with a slave station to be controlled by the second communication apparatus among slave stations to be controlled by the first communication apparatus based on the slave station information, and to generate control information for controlling the controlled slave station;
• and
• a transmitter to transmit the control information to the controlled slave station.

A communication method in a communication apparatus capable of controlling a slave station, the communication method comprising:

• acquiring slave station information including information indicating slave stations to be controlled by another communication apparatus capable of controlling a slave station;
• obtaining, as a controlled slave station of the communication apparatus, a slave station that does not overlap with a slave station to be controlled by the other communication apparatus based on the acquired slave station information;
• generating control information for controlling the controlled slave station of the communication apparatus;
• and
• transmitting the control information to the controlled slave station of the communication apparatus.
