Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If OFDMA modulation mode is used to allocate communication resources in a single frequency band, then the effective utilization rate of spectrums is improved, but multiple STAs cannot communicate simultaneously across multiple frequency bands
Solution Approach 1:
The patent segments the communication resource allocation by introducing separate trigger frames for each frequency band (2.4 GHz, 5 GHz, 6 GHz). Each trigger frame independently allocates resources within its specific band, enabling simultaneous multi-band communication while maintaining the OFDMA structure within each band. This segmentation resolves the contradiction by allowing spectrum efficiency within bands while enabling multi-band versatility.
Solution Approach 2:
The patent extends the resource allocation from a single frequency band dimension to multiple frequency band dimensions by using multiple trigger frames. Each trigger frame operates in a different frequency band dimension, allowing STAs to communicate simultaneously across multiple bands. This dimensional extension resolves the contradiction between single-band efficiency and multi-band capability.
2Productivity
If trigger frames are generated to allocate communication resources for multiple STAs in a single frequency band, then uplink communication efficiency is improved, but the system cannot support simultaneous communication in multiple frequency bands
Solution Approach 1:
The patent segments the uplink communication allocation into separate trigger frames for each frequency band. Each trigger frame maintains the efficient OFDMA resource allocation structure for its specific band, while the overall system achieves multi-band capability through this segmentation. This approach preserves uplink efficiency within each band while managing multi-band complexity through structured separation.
Solution Approach 2:
The patent uses preliminary action by generating trigger frames that pre-allocate communication resources for multiple STAs across multiple frequency bands before actual data transmission. This allows the system to establish multi-band communication patterns in advance, improving uplink efficiency while managing complexity through pre-planned resource allocation rather than dynamic coordination during transmission.
3Productivity
If multiple STAs communicate simultaneously in multiple frequency bands, then network throughput is improved, but the complexity of resource allocation increases
Solution Approach 1:
The patent segments the complex multi-band resource allocation problem into separate, manageable trigger frames for each frequency band. Each trigger frame handles resource allocation independently for its specific band, reducing the overall complexity while enabling simultaneous multi-band communication. This segmentation allows the system to achieve high throughput without overwhelming complexity in the allocation mechanism.
