Engineering Contradiction Analysis
1Productivity
If a throughput strategy is adopted to improve transmission rate, then transmission efficiency is improved, but latency increases
Solution Approach 1:
The patent implements dynamic transmission rate adjustment by continuously monitoring packet error rates and transitioning between different transmission rates based on channel conditions. The system dynamically switches between a first transmission rate and a second transmission rate to optimize both throughput and latency performance according to real-time wireless scene characteristics.
Solution Approach 2:
The patent changes the transmission rate parameter based on packet error rate measurements. When the packet error rate exceeds a threshold, the system transitions from a higher transmission rate to a lower transmission rate, and vice versa. This parameter adjustment resolves the contradiction by adapting the transmission rate to channel conditions, achieving both high efficiency and low latency when appropriate.
2Reliability
If a lower transmission rate is used to reduce packet error rate, then transmission reliability is improved, but transmission efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts transmission rate based on real-time packet error rate measurements. Instead of using a fixed low transmission rate, the system transitions between different transmission rates according to channel conditions, maintaining high reliability when needed while preserving transmission efficiency when channel conditions permit.
Solution Approach 2:
The patent implements parameter changes by adjusting the transmission rate based on packet error rate thresholds. When packet error rate is acceptable, the system uses higher transmission rates for better efficiency. When packet error rate exceeds thresholds, the system switches to lower transmission rates to improve reliability, thus resolving the contradiction between reliability and efficiency.
3Productivity
If rate adaptation mechanism is optimized for single user mode, then performance is improved, but adaptability to multi-user scenarios deteriorates
Solution Approach 1:
The patent creates a universal rate adaptation mechanism that functions effectively across multiple wireless scenarios including single user mode, multi-user mode, spatial reuse mode, and resource unit mode. The same core mechanism with packet error rate monitoring and dynamic transmission rate adjustment applies universally to all these different operational modes, achieving both optimized performance and broad adaptability.
Solution Approach 2:
The adaptive rate adjustment mechanism dynamically adapts to different wireless scenarios and user conditions. The system monitors packet error rates and adjusts transmission rates according to the specific characteristics of each scenario, whether single-user or multi-user, thereby maintaining high performance across diverse operational contexts without requiring scenario-specific optimizations.
