Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the amount of broadcast network information is increased to include inter-cell interference coordination data, then the network information completeness is improved, but the reliability of broadcast network information deteriorates due to reduced redundancy
Solution Approach 1:
The broadcast network information is segmented into multiple code blocks, which are then encoded separately. This segmentation allows the system to distribute the information across multiple transmission units, maintaining reliability through redundancy while accommodating increased information volume.
Solution Approach 2:
The patent changes the encoding parameters by introducing new code block sizes and code rates specifically for enhanced physical broadcast channels. These parameter adjustments optimize the balance between information capacity and transmission reliability, allowing more information to be transmitted without compromising error protection.
2Adaptability or versatility
If new features for inter-cell interference coordination are introduced, then the network functionality is improved, but latency is increased due to additional processing and transmission requirements
Solution Approach 1:
Multiple network information elements including inter-cell interference coordination data are merged into a single enhanced physical broadcast channel transmission. This consolidation reduces the number of separate transmission operations required, thereby reducing overall latency while maintaining enhanced functionality.
Solution Approach 2:
The broadcast information is prepared and encoded in advance with optimized code block structures, allowing for faster transmission once the signal is sent. This preliminary processing reduces the time required during actual transmission, mitigating latency issues introduced by enhanced functionality requirements.
3Productivity
If redundancy in broadcast channels is reduced to accommodate new information, then the transmission efficiency is improved, but the reliability of information reception deteriorates
Solution Approach 1:
The patent implements dynamic code rate selection and adaptive code block sizing based on channel conditions and information type. This dynamic approach allows the system to optimize transmission efficiency in real-time while maintaining adequate redundancy levels for reliable reception, balancing productivity and reliability requirements.
