Abstract:
1. A communication apparatus which forms a beacon group to perform communication, comprising: an acquisition unit constructed to acquire an offset amount between beacon periods of a first beacon group and a second beacon group, wherein the first and the second beacon groups are generated due to the communication apparatus entering a hibernation status, wherein the first beacon group is generated by a first device and the second beacon group is generated by a second device, and wherein the first and the second beacon groups are independent from each other; a determination unit constructed to determine a hibernation period such that an offset amount between beacon periods of the first and the second beacon groups does not exceed a predetermined amount during execution of hibernation on a basis of the acquired offset amount acquired by the acquisition unit; and a hibernation unit constructed to place the communication apparatus in the hibernation status in accordance with the hibernation period determined by the determination unit.
