Title: WIRELESS DEVICE AND PROCESSING METHOD FOR WIRELESS DEVICE
Abstract:
The present invention efficiently notifies a counterpart device whether a clock to be synchronized with said counterpart device has been correctly synchronized. This wireless device is provided with: a main control unit; a wireless control unit; and a clock synchronization management unit. In the main control unit, time is managed on the basis of a first clock (clock to be synchronized). In the wireless control unit, time is managed on the basis of a second clock (reference clock). The clock synchronization state is managed by the synchronization management unit. Information about the clock synchronization state is notified to another wirelessly-connected wireless device through transmission of frames.
