1. A wireless communication system comprising:
one or more communications apparatuses; and
a relay device, which is mobile,
wherein the relay device includes a transmitter configured to transmit a channel change signal to the one or more communications apparatuses, the channel change signal containing channel information that indicates results corresponding to interference levels of a plurality of channels in a frequency band available for use in uplink transmission from the one or more communications apparatuses to the relay device and specifying information used to specify a communications device subject to channel change, and
the one or more communications apparatuses include a channel setter configured to set a channel having an interference level lower than a threshold as a channel to be used for communications with the relay device when the specifying information contained in the channel change signal is applicable.
