Trigger Frame Acknowledgement Mechanism for Wireless Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networking technologies face inefficiencies in frame exchange procedures involving Trigger frames, particularly in reducing the number of transmissions and maintaining low latency, due to the need for explicit acknowledgement requests which increase network traffic.
Innovation Solution
Implementing an acknowledgement mechanism where a first wireless device transmits a frame with a field indicating a response frame type, and receives an acknowledgement frame and additional frames without immediate acknowledgement requests, allowing for customized triggering based on wireless station capabilities and operational environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit acknowledgement requests are used in frame exchange procedures, then reliability of frame transmission is improved, but network traffic increases and efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the explicit acknowledgement request mechanism from the frame exchange procedure. By removing this component, the system achieves higher network efficiency while maintaining reliability through implicit acknowledgement mechanisms and trigger frame-based coordination between access points and wireless stations.
Solution Approach 2:
The system implements self-service by having wireless stations automatically respond to trigger frames without requiring explicit acknowledgement requests. The station autonomously manages the frame exchange by detecting trigger frames and generating appropriate responses, thereby reducing network traffic while maintaining reliable communication.
2Productivity
If traditional frame exchange procedures are used, then network traffic is reduced, but latency increases and medium access speed decreases
Solution Approach 1:
The patent applies preliminary action by having the access point send trigger frames in advance that pre-configure the wireless station's response. This allows the station to prepare and transmit responses more quickly, reducing latency while maintaining efficient network operation through structured frame exchange procedures.
Solution Approach 2:
The system introduces dynamics by enabling adaptive frame exchange procedures where trigger frames can be customized based on station capabilities and operational environments. This dynamic approach allows optimization of latency and efficiency by tuning the frame exchange mechanism to specific operational conditions.
3Adaptability or versatility
If customized triggering mechanisms are implemented, then adaptability to different environments is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a trigger frame mechanism that can serve multiple functions and adapt to different operational environments. The same basic trigger frame structure supports various triggering mechanisms and station capabilities, reducing the need for multiple specialized mechanisms while maintaining high adaptability.
