1. An electronic device comprising:
- processing circuitry configured toreceive a first beacon from a first neighboring station and a second beacon from a second neighboring station;
determine a first offset value of the first beacon, the first offset value being calculated based on timing information received from the first neighboring station and first information held in the electronic device;
determine a second offset value of the second beacon, the second offset value being calculated based on timing information received from the second neighboring station and second information held in the electronic device;
determine a maximum offset value based on at least the first offset value and the second offset value; and
adjust a beacon transmitting timing according to the maximum offset value.

Abstract
In order to solve problems arising when a communication system such as a wireless LAN is constructed as a decentralized distributed type network without a relationship of control station and controlled stations such as a master station and slave stations, in a wireless communication system composed of a plurality of communication stations without a relationship of control station and controlled stations, respective communication stations transmit beacons with information concerning a network written thereon with each other to construct the network, and it becomes possible to make sophisticated judgment such as communication states of other communication stations by those beacons.

11. A method comprising:
-
receiving a first beacon from a first neighboring station and a second beacon from a second neighboring station; determining a first offset value of the first beacon, the first offset value being calculated based on timing information received from the first neighboring station and first information held in an electronic device; determining a second offset value of the second beacon, the second offset value being calculated based on timing information received from the second neighboring station and second information held in the electronic device; determining, by processing circuitry, a maximum offset value based on at least the first offset value and the second offset value; and adjusting, by the processing circuitry, a beacon transmitting timing according to the maximum offset value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
