Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spatial reuse is implemented only on main channel (20 MHz), then the mechanism is simple and reliable, but the space utilization rate is low and cannot be applied to high-bandwidth channels
Solution Approach 1:
The patent changes the parameter of channel bandwidth from fixed 20 MHz to variable bandwidths (20/40/80/160 MHz) by dynamically determining working bandwidth and rate based on target throughput calculations, enabling spatial reuse across multiple bandwidths while maintaining manageable complexity through standardized calculation procedures
Solution Approach 2:
The patent makes the spatial reuse mechanism universal by enabling it to work on multiple bandwidths (20/40/80/160 MHz) rather than being limited to a single main channel, allowing the same basic mechanism to serve different bandwidth requirements through standardized parameter determination procedures
2Productivity
If spatial reuse is extended to high-bandwidth channels, then the space utilization rate improves, but the channel parameter determination becomes more complex
Solution Approach 1:
The patent manages complexity by establishing clear parameter determination procedures that calculate working bandwidth and rate based on target throughput, which is derived from standardized SNR and MCS parameter relationships, making the extended high-bandwidth spatial reuse manageable through systematic calculation rather than ad-hoc adjustments
3Productivity
If multiple bandwidths are supported for spatial reuse, then the data transmission efficiency improves, but the calculation and determination process becomes more complex
Solution Approach 1:
The patent simplifies multi-bandwidth management by using standardized parameter relationships where target throughput is calculated from target SNR and reference MCS sets, which are determined through clear procedures based on channel state information, making the calculation process systematic rather than complex
Solution Approach 2:
The patent incorporates feedback mechanisms where the data receiving end provides channel state information including initial SNR values, which are then used by the data sending end to calculate target SNR and determine working parameters, creating a closed-loop system that manages complexity through coordinated information exchange
