Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless LAN technology supports high throughput and high-density environments, then communication speed and capacity are improved, but the complexity of frame structure and signal fields increases
Solution Approach 1:
The patent segments the signal field into multiple sub-fields (first signal sub-field and second signal sub-field) with specific functions. The first signal sub-field contains common information for multiple users, while the second signal sub-field contains user-specific information. This segmentation allows efficient multi-user transmission scheduling while maintaining manageable frame structure complexity through functional decomposition.
2Productivity
If resource allocation information is detailed and comprehensive, then multi-user transmission efficiency is improved, but the overhead of signal fields increases
Solution Approach 1:
The patent applies local quality by providing different levels of detail in different parts of the signal field. The first signal sub-field contains common resource allocation information that applies to multiple users, while the second signal sub-field contains detailed user-specific information only where needed. This differentiated approach optimizes transmission efficiency for targeted users while minimizing overall overhead by avoiding redundant information.
3Productivity
If bandwidth field and resource allocation field are added to enable multi-user transmission, then channel access efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing the signal field structure that serves multiple functions: the first signal sub-field provides common control information for multiple users, while the second signal sub-field provides user-specific resource allocation. This multi-functional design enables efficient multi-user transmission scheduling across different scenarios (downlink, uplink, mixed modes) while keeping the terminal implementation manageable through standardized field definitions.
