Wireless apparatus and wireless apparatus processing method

A wireless apparatus, comprising:

• processing circuitry configured to
• manage time using a first clock;
• manage time using a second clock;
• manage a clock synchronization state between the first clock and the second clock;
• and
• transmit a frame to another wireless apparatus that is wirelessly connected to the wireless apparatus, wherein
• the frame includes synchronization information regarding the clock synchronization state including at least a synchronization status between the first clock and the second clock, and the frame further includes associating information for associating the first clock with the second clock, and
• the associating information includes information regarding a clock difference between the first clock and the second clock.

A wireless apparatus, comprising:

• processing circuitry configured to
• manage time using a first clock;
• manage time using a second clock;
• and
• detect synchronization information regarding a clock synchronization state by receiving a frame from another wireless apparatus wirelessly connected to the wireless apparatus;
• and
• a display configured to display a user interface based on the information regarding the clock synchronization state, wherein
• the synchronization information includes information regarding a synchronization status between the first clock and the second clock;
• and
• the synchronization status indicates:
• two types of status, synchronous and asynchronous, or
• three types of status, synchronous, asynchronous, and unsynchronizable due to vigorous synchronization criteria.
