Engineering Contradiction Analysis
1Adaptability or versatility
If multiple coding schemes are used to support different usage scenarios, then adaptability is improved, but device complexity increases
Solution Approach 1:
The coding unit is divided into multiple independent coding schemes (first coding scheme and second coding scheme), each optimized for specific usage scenarios. This segmentation allows the system to select appropriate coding schemes based on traffic requirements, improving adaptability while keeping each individual coding scheme relatively simple.
Solution Approach 2:
The patent implements dynamic selection between different coding schemes based on real-time traffic conditions and usage scenarios. The coding unit can switch between first coding scheme (suitable for EMBB), second coding scheme (suitable for URLLC), and other coding schemes (suitable for eMTC) according to the specific communication requirements, making the system adaptable without permanently increasing complexity.
2Productivity
If multiple coding schemes with different coding rates are implemented, then communication efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs multiple coding schemes with different coding rates (e.g., different mother code rates for LDPC) to optimize communication efficiency for various usage scenarios. By changing coding parameters according to traffic requirements, the system achieves high communication efficiency without requiring extremely precise manufacturing, as the parameter adjustments provide flexibility to accommodate implementation variations.
