Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in Wi-Fi networks, lack efficient mechanisms for peer wireless stations to coordinate and manage communication pauses during coexistence events without relying on intermediate access points, leading to inefficiencies in power usage and communication time.
Innovation Solution
Implementing a mechanism where peer wireless stations can transmit a pause indication frame, including a time duration field, to pause and resume peer-to-peer data communication sessions using Wi-Fi control or management frames, allowing for coordinated management of coexistence events and power savings.

1Use of energy by moving object
If peer wireless stations transmit pause indication frames to coordinate communication pauses during coexistence events, then power usage efficiency is improved and communication time losses are reduced, but device complexity increases due to the need for additional frame structures and coordination protocols
Solution Approach 1:
The pause indication frame structure is designed to be multi-functional, serving both as a coordination signal for coexistence events and as a general-purpose communication pause mechanism. This universal design allows the same frame structure to handle multiple scenarios (coexistence events, buffer empty conditions, flow control) without requiring separate dedicated frames for each case, thereby improving power efficiency across different operational contexts while minimizing the increase in device complexity.
Solution Approach 2:
The invention utilizes parameter changes within existing Wi-Fi frame structures to convey pause indication information. By modifying parameters such as setting specific bits in control fields or adjusting timing parameters in management frames, the system can signal pause conditions without fundamentally changing the frame structure. This approach enables effective coordination of coexistence events and power savings while keeping the increase in device complexity minimal.
2Loss of time
If peer wireless stations implement pause indication mechanisms for coexistence event coordination, then communication time efficiency is improved, but the complexity of communication protocols increases
Solution Approach 1:
The pause indication mechanism enables preliminary action by allowing wireless stations to proactively signal upcoming coexistence events before they occur. By transmitting pause indication frames in advance, stations can coordinate their communication schedules ahead of time, preventing communication time losses during coexistence events. This advance coordination reduces the need for complex real-time protocol negotiations, thereby improving communication time efficiency while keeping protocol complexity manageable.
Solution Approach 2:
The invention implements a feedback mechanism where receiving stations acknowledge pause indication frames and provide status information about their communication state. This feedback loop allows stations to coordinate their pause and resume actions efficiently, ensuring that communication resumption occurs at optimal times. The feedback mechanism simplifies the overall protocol by providing clear state information, reducing the complexity of coordination while improving communication time efficiency.
