Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed code block segmentation manner is used in the LTE system, then the encoding and decoding processes are simple, but the flexibility of encoding and decoding processes is limited
Solution Approach 1:
The patent applies dynamics by enabling the terminal device to dynamically select from multiple preset code block segmentation manners based on received indication information. Instead of a fixed segmentation approach, the system allows adaptive switching between different segmentation strategies (e.g., different numbers of code blocks, different segmentation positions) to match varying channel conditions and terminal capabilities, thereby improving flexibility without permanently increasing device complexity
Solution Approach 2:
The patent utilizes parameter changes by varying the code block segmentation parameters (number of code blocks, segmentation points) according to different indication information values. The terminal device can adjust segmentation parameters based on the received indication, allowing the system to optimize encoding/decoding performance for different scenarios while maintaining a manageable level of complexity through preset options
2Productivity
If parallel encoders are used to reduce encoding delay, then encoding speed is improved, but the existing fixed segmentation manner cannot fully utilize parallel processing capabilities
Solution Approach 1:
The patent enables dynamic adaptation of code block segmentation to match the terminal's parallel processing capabilities. By receiving indication information that specifies different segmentation manners, the system can dynamically adjust the number and size of code blocks to fully utilize the available parallel encoders, thereby maximizing encoding speed improvement while maintaining adaptability to different hardware configurations
Solution Approach 2:
The patent applies segmentation by dividing the data into multiple code blocks with flexible boundaries based on the indication information. This allows the system to create an optimal number of segments that matches the parallel encoder architecture, enabling each encoder to process a code block simultaneously and thus fully utilizing parallel processing capabilities to improve encoding productivity
3Reliability
If code block segmentation is performed to handle large data quantities, then data processing capability is improved, but the fixed segmentation manner reduces flexibility for future communication requirements
Solution Approach 1:
The patent achieves universality by designing a multi-functional code block segmentation system that can adapt to various future communication requirements. The terminal device stores multiple preset segmentation manners and can select appropriate ones based on received indication information, making the system universally applicable to different scenarios including URLLC, eMBB, and other future 5G services, thereby maintaining flexibility while ensuring reliable data processing capability
