A radio communication system includes one master station which performs
transmission without being controlled by another radio station and which
is configured to independently set a channel for use in a radio
communication, and at least one slave station which belongs to the one
master station and whose radio communication channel used and
transmission/reception operations are controlled by the master station.
When detecting an interference signal which disturbs the radio
communication during operation, the one master station or the at least
one slave station sets a first modulation scheme applied to the radio
communication to the same second modulation scheme as a modulation scheme
used in broadcast in order to convey information necessary for an evasive
action to move to another radio communication channel.
