Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing wireless communication technologies in the 60 GHz frequency band are used, then legacy system compatibility is maintained, but high data rate and low latency requirements for metaverse applications cannot be met
Solution Approach 1:
The patent implements dynamic waveform selection and scalable numerology designs that allow the system to adapt between different subcarrier spacing configurations (e.g., 125 kHz, 250 kHz, 500 kHz, 1 MHz) based on application requirements. This enables the system to dynamically switch between legacy-compatible modes and high-performance modes optimized for metaverse applications, resolving the contradiction between maintaining compatibility and achieving high data rates.
Solution Approach 2:
The patent changes key waveform parameters including subcarrier spacing, cyclic prefix length, and FFT size to create scalable numerology designs. By adjusting these parameters, the system can optimize performance for different application scenarios while maintaining backward compatibility with legacy IEEE 802.11ac/ax/be systems, thereby achieving both high productivity and adaptability.
2Productivity
If new scalable waveform designs are implemented to meet high data rate requirements, then system complexity increases
Solution Approach 1:
The patent segments the waveform design into modular components including separate handling of different subcarrier spacing configurations, independent cyclic prefix structures, and distinct pilot patterns. This modular segmentation allows each component to be optimized independently while maintaining overall system manageability, reducing implementation complexity despite the scalable nature of the design.
Solution Approach 2:
The patent creates a universal waveform framework that can function across multiple application scenarios by supporting both legacy WLAN operations and next-generation metaverse applications through configurable numerology parameters. This multi-functionality is achieved through a unified signal processing architecture that adapts to different requirements without requiring separate dedicated systems, thereby controlling complexity.
3Adaptability or versatility
If flexible numerology options are provided for different applications, then adaptability improves, but system design and standardization difficulty increases
Solution Approach 1:
The patent establishes a systematic parameter change framework where subcarrier spacing, cyclic prefix length, and other numerology parameters are defined in discrete, standardized steps (e.g., 125 kHz, 250 kHz, 500 kHz, 1 MHz). This structured approach to parameter variation provides the needed flexibility for different applications while maintaining manageable standardization complexity through clear, defined parameter sets rather than continuous variations.
