Engineering Contradiction Analysis
1Length of stationary object
If relay communication is used to extend communication distance for wearable terminals, then communication coverage is improved, but communication quality and reliability deteriorate
Solution Approach 1:
The patent segments the resource pool into multiple sub-resource pools and further divides them into individual resource units for different wireless links. This segmentation allows independent management and optimization of resources for each relay connection, ensuring that quality requirements can be met for each segment while achieving extended communication distance through multiple relays
Solution Approach 2:
The patent applies local quality by allocating different resource pool configurations to different wireless links based on their specific requirements. Each link between a relay communication apparatus and a remote communication apparatus receives individually optimized resource allocation, ensuring that local communication quality requirements are met while enabling long-distance communication through the relay chain
2Device complexity
If resource pool is shared among multiple relay communication apparatuses, then device complexity is reduced, but communication quality deteriorates
Solution Approach 1:
The resource pool is segmented into sub-resource pools and further divided into resource units that can be individually allocated to different wireless links. This hierarchical segmentation maintains manageable complexity at each level while ensuring dedicated resources for each communication link, preventing quality deterioration despite serving multiple relays
Solution Approach 2:
The patent implements dynamic resource allocation where the base station individually controls allocation of resource units to each wireless link based on acquired communication state information. This dynamic adjustment allows the system to adapt to changing conditions while maintaining communication quality, and the segmented structure keeps the complexity of this dynamic management tractable
3Reliability
If individualized resource allocation is implemented for each wireless link, then communication quality is improved, but device complexity increases
Solution Approach 1:
The patent reduces allocation complexity through hierarchical segmentation: the resource pool is divided into sub-resource pools, which are further divided into resource units. This segmentation allows individualized allocation to be performed at the fine-grained resource unit level while managing complexity at higher levels through the structured hierarchy, enabling quality improvement without prohibitive complexity increase
