PROBLEM TO BE SOLVED: To stably and efficiently transmit/receive signals while avoiding collision of signals even in the case where a repeater is used between a controlled device and a control device, in two-way radio communication between the controlled device and the control device in a radio communication system.SOLUTION: A radio communication system 1 comprises a controller 2 (control device) which performs two-way radio communication with a switch 4 (controlled device) directly or via a repeater 5. While defining a control signal to be transmitted as a starting point, the controller 2 sets time slots including a control signal relay slot which is specified in accordance with the number of repeaters 5, a response signal transmission slot which is specified in accordance with the number of switches 4, and a response signal relay slot which is specified in accordance with the number of repeaters 5. The switch 4 determines a slot to be used in accordance with a controlled device number, and the repeater 5 determines a slot to be used in accordance with a repeater number. |
