Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed time interval units and channel mappings are used in LTE system, then system complexity is reduced and implementation is simplified, but adaptability to different service demands and user equipment conditions deteriorates
Solution Approach 1:
The patent divides transmission resources into multiple resource groups (first resource group, second resource group, etc.), each with independent configuration parameters. This segmentation allows different service types to be allocated to different resource groups with customized time interval units and channel mappings, thereby improving adaptability while maintaining manageable system complexity through structured organization.
Solution Approach 2:
The patent introduces dynamic configuration of physical layer transmission parameters, where time interval units and channel mappings can be adjusted based on service requirements and user equipment conditions. This dynamic approach enables the system to adapt to varying demands without requiring complete redesign of the fixed framework, balancing flexibility with implementation complexity.
2Ease of operation
If fixed resource allocation units are used, then resource management is simplified, but resource allocation efficiency for diverse services deteriorates
Solution Approach 1:
The patent applies local quality by configuring different resource allocation parameters for different resource groups. Each resource group can have customized time interval lengths, channel mapping configurations, and resource block allocations tailored to specific service requirements. This allows efficient resource allocation for diverse services while maintaining simplified management through the resource group structure.
3Device complexity
If fixed channel mapping positions are used, then channel management is simplified, but flexibility in optimizing transmission performance deteriorates
Solution Approach 1:
The patent enables dynamic adjustment of channel mapping positions within the resource group framework. Different resource groups can have different channel mapping configurations optimized for their specific service types, while the overall management remains simplified through the standardized resource group structure and configuration signaling.
