Communication device, communication method, and communication system

A communication method of a communication device comprising:

• determining that one of the communication device and a counterpart communication device communicating with the communication device is to function as a group owner (GO) device;
• and
• determining a GO intent value of the counterpart communication device,
• transmitting a GO negotiation request frame including a GO intent value of the communication device and the GO intent value of the counterpart communication device to the counterpart communication device, and
• receiving a GO negotiation response frame indicating that the counterpart communication device agrees to the GO intent value of the counterpart communication device, from the counterpart communication device,
• wherein the GO intent value indicates a degree of intention to be the GO device.

A communication system comprising:

• a communication device configured to:
• determine that one of the communication device and a counterpart communication device communicating with the communication device is to function as a group owner (GO) device,
• determine a GO intent value of the counterpart communication device, and transmit a GO negotiation request frame including a GO intent value of the communication device and the GO intent value of the counterpart communication device to the counterpart communication device;
• and the counterpart communication device configured to:
• receive the GO negotiation request frame from the communication device, and transmit a GO negotiation response frame indicating that the counterpart communication device agrees to the GO intent value of the counterpart communication device to the communication device in response to the GO negotiation request frame,
• wherein the GO intent value indicates a degree of intention to be the GO device.

A communication method of a communication device and a counterpart communication device communicating with the communication device, the communication method comprising:

• performing a scan operation, by the communication device and the counterpart communication device, to transmit probe request frames to each other;
• performing a find operation, by the counterpart communication device, in response to a probe request frame transmitted from the communication device, to transmit a probe response frame to the communication device to detect each other;
• and
• performing a group formation operation to determine a device to function as a group owner (GO) device from the communication device and the counterpart communication device, wherein the performing the group formation operation comprises:
• determining, by the communication device, that one of the communication device and the counterpart communication device communicating with the communication device is to function as the group owner (GO) device,
• determining, by the communication device, a GO intent value of the counterpart communication device,
• transmitting, by the communication device, a GO negotiation request frame including a GO intent value of the communication device and the GO intent value of the counterpart communication device to the counterpart communication device;
• and
• transmitting, by the counterpart communication device, to the communication device, a GO negotiation response frame indicating that the counterpart communication device agrees to the GO intent value of the counterpart communication device,
• wherein the GO intent value indicates a degree of intention to be the GO device.
