Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed labeling configuration is used for modulation constellations, then device complexity is reduced, but throughput and communication reliability deteriorate due to sub-optimal utilization of UE capabilities
Solution Approach 1:
The patent implements dynamic selection of labeling configurations based on UE capability information. The network node receives capability indicators from the UE and dynamically chooses between different labeling configurations (e.g., first labeling configuration for legacy UEs, second labeling configuration for advanced UEs). This dynamic adaptation enables the system to optimize throughput for capable devices while maintaining compatibility with simpler devices, resolving the contradiction between productivity improvement and device complexity.
Solution Approach 2:
The patent changes the parameter of labeling configuration selection based on UE capability information. By introducing capability indicators that specify which labeling configurations a UE supports, the system can adjust the labeling parameter dynamically. This allows advanced UEs to use optimal labeling configurations for higher throughput while legacy UEs continue using standard configurations, thereby improving overall system productivity without forcing complexity on all devices.
2Reliability
If capability information exchange and dynamic configuration selection are implemented, then throughput and reliability improve, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies preliminary action by having the UE transmit capability information indicating supported labeling configurations before actual data transmission begins. This capability exchange occurs during initial connection or configuration phases, allowing the network node to pre-determine the appropriate labeling configuration. By resolving the configuration selection in advance, the system avoids repeated signaling during data transmission, thereby improving communication reliability while minimizing signaling overhead.
Solution Approach 2:
The patent implements feedback mechanisms where the UE provides capability information about supported labeling configurations to the network node. The network node uses this feedback to select an appropriate configuration and communicates the selection back to the UE. This feedback loop ensures that both parties use consistent labeling configurations, improving communication reliability. The feedback is efficiently designed to convey only necessary capability indicators, balancing reliability improvement with minimal signaling overhead.
3Productivity
If legacy UE compatibility is maintained with standard labeling configurations, then ease of operation is preserved, but performance and throughput are limited
Solution Approach 1:
The patent achieves universality by designing the labeling configuration system to serve multiple UE types simultaneously. The network node can select from multiple labeling configurations based on UE capability - using standard configurations for legacy UEs to maintain ease of operation, and advanced configurations for capable UEs to maximize productivity. This multi-functional approach allows the same system to accommodate both legacy and advanced devices without compromising either compatibility or performance.
Solution Approach 2:
The patent applies local quality by allowing different labeling configurations to be applied to different UEs based on their individual capabilities. Rather than forcing a uniform configuration across all devices, the system tailors the labeling configuration to each UE's specific capabilities. Legacy UEs receive standard configurations ensuring ease of operation, while advanced UEs receive optimized configurations maximizing data transmission efficiency, thus resolving the contradiction through localized optimization.
