Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted to multiple terminals using individual MAC protocol data units, then data transmission reliability is improved, but transmission efficiency deteriorates due to increased overhead and channel occupancy time
Solution Approach 1:
The patent combines multiple individual MAC protocol data units into a single aggregate MAC protocol data unit that can be transmitted to multiple terminals simultaneously. This merging approach maintains data transmission reliability by preserving individual terminal identification and data separation while improving transmission efficiency by reducing channel occupancy time and overhead associated with multiple separate transmissions.
2Speed
If channel bandwidth is increased to improve data transmission speed, then communication efficiency is improved, but device complexity increases due to requirements for advanced MIMO and modulation technologies
Solution Approach 1:
The patent segments the aggregated data into multiple spatial streams that are transmitted through multiple antennas using MIMO technology. This segmentation allows the system to achieve higher data transmission speeds by utilizing multiple parallel channels while managing device complexity through standardized MIMO implementations that are already integrated into modern wireless communication hardware.
Solution Approach 2:
The patent employs high-density modulation schemes such as 256-QAM to increase the amount of data transmitted per symbol, thereby improving data transmission speed. This parameter change in modulation depth allows the system to achieve higher throughput while utilizing existing modulation capabilities in contemporary wireless devices, thus managing complexity effectively.
3Reliability
If multiple antennas are deployed to improve data transmission reliability through MIMO, then communication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple spatial streams from multiple antennas into a unified aggregate MAC protocol data unit transmission framework. This approach maximizes the reliability benefits of MIMO technology by ensuring that all spatial streams contribute to the same aggregated data transmission, while managing device complexity through a unified processing architecture that handles multiple antennas systematically.
