Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different signaling is used for different scenarios or information fields to indicate cell scheduling mechanism, then scheduling flexibility is improved, but signaling overhead increases
Solution Approach 1:
The patent applies universality by designing a unified indication mechanism where a single signaling field can indicate transmission parameters for multiple cells across different scheduling scenarios. Instead of having separate indication mechanisms for each scenario or cell, the invention creates a universal indication structure that adapts to various scheduling configurations, thereby reducing signaling overhead while maintaining scheduling flexibility.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the interpretation of indication information based on scheduling configuration parameters. The indication field values are mapped to different transmission parameter sets depending on the scheduling scenario, allowing the system to adapt to different conditions without requiring separate signaling for each case. This parameter-based adaptation resolves the contradiction by enabling scenario-specific behavior through unified signaling.
2Measurement precision
If separate indication mechanisms are used for each cell, then transmission parameter accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies merging by combining multiple cell indication mechanisms into a single unified indication structure. Instead of maintaining separate indication fields for each cell, the invention merges them into one compact indication mechanism that can represent transmission parameters for multiple cells. This reduces device complexity while preserving the ability to accurately indicate parameters for each scheduled cell through the unified structure.
3Quantity of substance
If compact indication format is used, then signaling overhead is reduced, but information completeness deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the indication information into multiple fields or segments within the unified indication structure. Each segment carries specific transmission parameter information for different cells or scenarios. This segmentation allows compact representation of multiple parameters without losing information completeness, as each necessary parameter is systematically organized in dedicated segments within the compact format.
Solution Approach 2:
The patent utilizes another dimension by organizing indication information in a multi-dimensional structure rather than a simple linear format. The unified indication mechanism employs multiple dimensions (such as different field segments, bit positions, or hierarchical levels) to encode transmission parameters for multiple cells. This dimensional organization enables compact representation while preserving complete information, as the multi-dimensional structure efficiently packs more information into fewer bits through systematic encoding.
