When radio communication units communicate with each other, communication is performed using a hopping pattern obtained by shifting a hopping pattern that is used in communication between a radio control unit and the radio communication units.

DETAILED DESCRIPTION An object of the present invention is to provide a method through which notification is given of hopping patterns in simple fashion and in a short period of time.
Another object of the present invention is to reduce the memory capacity needed to store the hopping patterns of a terminal device.
Yet another object of the present invention is to select a hopping pattern employed in communication between a main unit and terminal devices and a hopping pattern employed in communication between terminal devices in such a manner that identical frequency channels are not used at the same time.
Other features and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the figures thereof.
