1. A communication apparatus configured to operate as a first mobile terminal in communication with a first base station and comprising a control circuit that performs control to:
detect a signal that is transmitted by a second mobile terminal to a second base station via a first frequency channel of a plurality of predetermined frequency channels identified for multi-station multi-channel communications;
receive a multichannel information signal from the first base station via a frequency channel of the plurality of predetermined frequency channels that has been predetermined for transmitting multichannel information signals by multiple base stations, the multichannel information signal including channel information and bandwidth information;
in response to the multichannel information signal, based on the channel information and the bandwidth information:
select at least two frequency channels from a plurality of predetermined frequency channels available to the mobile terminal for transmitting data,
wherein the selected at least two of the frequency channels are any of the plurality of predetermined frequency channels other than:
the first frequency channel of the detected first signal, and
the frequency channel of the plurality of predetermined frequency channels that has been predetermined for transmitting multichannel information signals; and

transmit second signals to the first base station via the selected at least two of the frequency channels;

receive the data from the first base station via the selected at least two of the frequency channels; and
transmit an acknowledgement to the received data via at least one of the selected at least two of the frequency channels.
