Wi-Fi GO Intent Negotiation for Stable P2P Group Formation

Solution Overview

Problem

In peer-to-peer (P2P) communication, determining a stable group owner (GO) device is challenging due to ambiguous GO intent value exchanges between devices, leading to inconsistent or unintended connections.

Innovation Solution

A communication device and method that transmit and receive GO intent values using Wi-Fi GO negotiation request and response frames to explicitly determine and confirm the GO device, ensuring stable group formation based on intended device roles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If devices exchange GO intent values in P2P communication, then connection establishment is enabled, but ambiguous intent value exchanges lead to inconsistent or unintended connections

Engineering Contradiction:

Improveconnection establishmentVSAvoidconnection consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by having devices determine their GO intent values before the actual connection establishment process. The communication device determines whether it should function as a GO device or a client device based on pre-configured GO intent values and device types before initiating P2P connection, ensuring that the role assignment is decided in advance rather than ambiguously during connection negotiation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by having the communication device transmit information indicating the determined GO device to the counterpart communication device. This feedback mechanism ensures that both devices have consistent understanding of which device should function as GO, preventing inconsistent or unintended connections by confirming the role assignment through explicit information exchange.

Inventive Principle:

Principle #23Feedback

2Speed

If devices automatically determine GO role without explicit confirmation, then connection speed is improved, but GO device stability is compromised

AI summary

Disclosed are a communication device, a communication method, and a communication system. The communication system includes a communication device configured to determine a device to function as a group owner (GO) device from the communication device and a counterpart communication device communicating with the communication device and transmit information indicating which one of the communication device and the counterpart communication device is the GO device to the counterpart communication device, and the counterpart communication device configured to receive the information indicating which one of the communication device and the counterpart communication device is the GO device from the communication device and transmit, in response to receiving the information, a signal for agreeing to the information indicating which one of the communication device and the counterpart communication device is the GO device to the communication device.
