1. A communication apparatus comprising:circuitry configured to:
receive first beacons from at least one peripheral communication station;
generate a second beacon on which beacon timing information related to a reception time of a first beacon having an indication among the first beacons received from the at least one peripheral communication station is placed, based on a change in reception state of at least one of the first beacons, wherein the circuitry places information on the second beacon indicating whether or not a reception state of a first beacon has changed and wherein the change in the reception state of the first beacon comprises at least one of the following: disappearance of a first beacon which has been periodically received thus far, starting of reception of a first beacon which has not been observed thus far, change in the transmission interval of a first beacon which has been received thus far, and change in proximity in reception intervals of first beacon signals received from different peripheral communication stations;
transmit the second beacon generated by the circuitry; and
control transmission timing of the second beacon so as to avoid a collision with the first beacons transmitted from the at least one peripheral communication station.
