Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems often use common channel access parameters for all stations within a basic service set, which may not be optimal for various applications, leading to suboptimal key performance indicators such as throughput and latency.
Innovation Solution
Implementing individually set channel access parameters for each station or group of stations, allowing for tailored settings that differentiate access categories and traffic types, and are conditional on specific conditions or features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If common channel access parameters are used for all stations within a basic service set, then system complexity is reduced and ease of operation is improved, but key performance indicators such as throughput and latency deteriorate
Solution Approach 1:
The patent segments the channel access parameters by creating separate parameter sets for different stations rather than using a single common set for all stations. This allows each station to have customized parameters optimized for its specific traffic characteristics and service requirements, thereby improving throughput while maintaining manageable complexity through structured parameter organization.
Solution Approach 2:
The patent applies local quality by allowing different stations to use different channel access parameters tailored to their specific needs. Each station can have customized AIFSN, CWmin, CWmax, and TXOP limit values based on its traffic type and performance requirements, enabling optimal local performance rather than compromising for global uniformity.
2Adaptability or versatility
If common channel access parameters are used for all stations, then device complexity is reduced, but adaptability to different applications and traffic types deteriorates
Solution Approach 1:
The patent divides the parameter configuration into multiple station-specific sets, allowing the system to adapt to different applications and traffic types. Each station can be assigned parameters appropriate for its specific requirements, enhancing adaptability while the segmented structure keeps complexity manageable through organized parameter groups.
Solution Approach 2:
The patent enables local quality by customizing channel access parameters for individual stations based on their specific traffic characteristics and service requirements. This allows high-priority traffic to receive aggressive parameters while low-priority traffic uses conservative parameters, achieving high adaptability without requiring complete system redesign for each scenario.
3Productivity
If individually set channel access parameters are implemented for each station, then throughput and latency performance are improved, but device complexity and parameter management complexity increase
Solution Approach 1:
The patent manages the complexity of individualized parameters by segmenting them into organized sets for each station. This structured approach allows the system to track and manage multiple parameter sets efficiently, reducing the operational burden despite the increased number of parameters. The segmentation enables systematic updates and modifications without overwhelming complexity.
4Productivity
If individually set channel access parameters are implemented for each station, then key performance indicators such as throughput and latency are improved, but ease of operation deteriorates
Solution Approach 1:
The patent eases operation despite individualized parameters by segmenting the parameter management into structured sets. This organization allows operators to manage parameters systematically rather than dealing with a chaotic array of individual settings, maintaining ease of operation while achieving high throughput through customized parameter assignments.
