Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified transport block size determination method is used across different bandwidth resources, then the device complexity is reduced, but the measurement precision of resource allocation accuracy deteriorates
Solution Approach 1:
The patent segments the bandwidth resource into multiple bandwidth parts (BWPs), each with its own configuration information for transport block size determination. This allows different BWPs to have customized resource allocation parameters while maintaining a structured framework, thus improving accuracy without excessive complexity increase.
Solution Approach 2:
The patent applies local quality by allowing different bandwidth parts to have different configuration information (resource element quantities, modulation orders, code rates) tailored to their specific requirements. This enables optimized transport block size determination for each local bandwidth resource while maintaining overall system coordination.
2Reliability
If different configuration information is used for different bandwidth resources, then the reliability of data transmission is improved, but the device complexity increases
Solution Approach 1:
The patent introduces dynamic switching between different bandwidth parts, each with its own configuration. The system can dynamically select appropriate BWPs based on channel conditions and service requirements, improving reliability through adaptive resource allocation while managing complexity through standardized switching mechanisms.
Solution Approach 2:
The patent creates a universal framework where multiple bandwidth parts with different configurations can coexist under a unified management structure. The same determination method works across different BWPs, providing multi-functionality that handles diverse resource allocation scenarios without proportionally increasing complexity.
3Ease of operation
If transport block size is determined without considering specific bandwidth resource characteristics, then the ease of operation is improved, but the productivity of data transmission deteriorates
Solution Approach 1:
The patent performs preliminary configuration of bandwidth parts with their specific parameters (resource element quantities, modulation orders, code rates) before data transmission. This pre-configuration allows the determination method to operate simply by selecting the appropriate BWP configuration, maintaining ease of operation while ensuring optimized productivity through pre-calculated optimal parameters.
