Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronization signal block index management is improved, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by utilizing the SS block index as a scrambling parameter for the physical broadcast channel. This changes the scrambling initialization from traditional parameters to include the SS block index, thereby improving communication reliability through better synchronization while managing device complexity through efficient parameter utilization.
Solution Approach 2:
The patent implements multi-functionality by using the SS block index for multiple purposes: synchronization identification and scrambling initialization. This universal use of the SS block index improves communication reliability without requiring additional separate mechanisms, thus managing device complexity effectively.
2Productivity
If synchronization accuracy is improved through SS block index scrambling, then communication efficiency is improved, but information processing complexity increases
Solution Approach 1:
The patent changes the scrambling initialization parameters to incorporate the SS block index, which improves synchronization accuracy and communication efficiency. The parameter change is implemented in a way that leverages existing index structures, thereby limiting the increase in information processing complexity.
Solution Approach 2:
The system performs self-service by using the SS block index that is already generated for synchronization purposes to also drive the scrambling process. This eliminates the need for separate scrambling initialization mechanisms, improving communication efficiency while keeping information processing complexity manageable.
