Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sidelink resource pool selection is used, then resource allocation is simple, but urgent packet transmission experiences delays and inefficiencies
Solution Approach 1:
The patent implements dynamic resource pool selection where the UE adapts its resource pool choice based on real-time conditions including traffic load, packet size, and network state. This allows the system to respond flexibly to urgent packet requirements rather than using static resource allocation, thereby improving delivery reliability while managing complexity through conditional decision-making
Solution Approach 2:
The patent changes multiple parameters simultaneously to optimize urgent packet transmission: selecting from multiple resource pools based on traffic load conditions, adjusting resource pool size based on packet size, and modifying selection criteria based on network conditions. This multi-parameter adaptation enables the system to prioritize urgent packets effectively
2Productivity
If dynamic resource pool selection based on multiple parameters is implemented, then urgent packet transmission efficiency improves, but system complexity increases
Solution Approach 1:
The patent employs parameter changes by selecting different resource pools based on traffic load conditions, adjusting resource allocation based on packet size, and modifying selection behavior based on network conditions. This allows efficient urgent packet transmission through adaptive parameter adjustment while keeping the underlying mechanism manageable
Solution Approach 2:
The patent applies local quality by implementing different resource pool selection strategies for different types of traffic and network conditions. Instead of a uniform approach, the system tailors resource pool characteristics (size, location, availability) to specific transmission requirements, improving urgent packet efficiency without requiring complete system redesign
3Loss of time
If resource pools are selected based on traffic load and network conditions, then latency is reduced, but measurement and detection difficulty increases
Solution Approach 1:
The patent implements feedback mechanisms where the UE monitors network conditions, traffic load, and transmission outcomes to inform subsequent resource pool selections. This feedback loop enables latency reduction through adaptive decision-making while managing measurement complexity by focusing on key performance indicators and using historical data to guide future selections
Data Source
AI summary
A wireless device receives one or more messages indicating transmission resource pools of a sidelink, where the transmission resource pools comprise a first transmission resource pool and a second transmission resource pool. In some cases, the wireless device is allowed to use the second transmission resource pool based on one or more thresholds associated with sidelink transport blocks. Based on a transport block meeting the one or more thresholds, the wireless device selects one or more sidelink resources from the second transmission resource pool. The wireless device transmits the transport block via the one or more sidelink resources.
