Wireless Communication Apparatus Dynamic Acknowledgement Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies in acknowledging data transmission errors, particularly when the priority of data items is not dynamically adjusted based on changing wireless transmission path conditions, leading to decreased convenience and increased error rates.
Innovation Solution
A wireless communication apparatus with a control unit that generates and adjusts acknowledgement request information based on data unit priorities, error rates, congestion levels, and transmission buffer states to optimally select data units requiring acknowledgement responses, thereby improving transmission efficiency and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed priority-based acknowledgement system is used, then delivery acknowledgement processing is simplified, but convenience decreases when wireless transmission path conditions change
Solution Approach 1:
The patent implements dynamic adjustment of acknowledgement requests based on real-time wireless transmission path conditions. The control unit monitors transmission path state and dynamically determines which data units require acknowledgement responses, transitioning from a static priority-based system to an adaptive system that responds to changing channel conditions, thereby resolving the contradiction between processing simplicity and adaptability.
2Reliability
If acknowledgement requests are sent for all data units, then transmission reliability is improved, but transmission efficiency decreases due to increased overhead
Solution Approach 1:
The patent applies local quality by selectively requesting acknowledgements only for specific data units based on their individual characteristics and current transmission path conditions. Instead of uniformly requesting acknowledgements for all data units, the control unit makes localized decisions about which data units need confirmation, thereby maintaining reliability for critical data while improving overall transmission efficiency by reducing unnecessary acknowledgement overhead.
3Productivity
If priority-based acknowledgement selection is used, then transmission efficiency is improved, but error rate increases when transmission path conditions deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the control unit continuously monitors transmission path conditions and uses this information to adjust acknowledgement request decisions. When transmission path conditions deteriorate, the system receives feedback about increased error rates and responds by requesting acknowledgements for additional data units, thereby maintaining reliability while preserving efficiency through intelligent, condition-based selection rather than rigid priority rules.
