Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed resource selection method is used for inter-UE coordination messages, then the procedure is simple, but the available resources may be insufficient and interference with data transmissions cannot be minimized
Solution Approach 1:
The patent implements dynamic resource selection by allowing the UE to adjust the resource selection window size based on real-time available resource conditions. The window size is dynamically modified to ensure sufficient available resources for inter-UE coordination messages while adapting to changing network conditions, thereby resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent changes the parameter of resource selection window size dynamically. By adjusting this parameter based on available resource ratios and interference conditions, the system can ensure adequate resources for coordination messages without requiring overly complex procedures, thus improving reliability while managing complexity through parameter adaptation.
2Reliability
If the resource selection window is enlarged to ensure sufficient available resources, then the availability of resources improves, but the time for resource selection increases
Solution Approach 1:
The patent dynamically adjusts the resource selection window size based on real-time available resource conditions. When resources are abundant, a smaller window is used to reduce selection time. When resources are scarce, the window is enlarged to ensure adequate available resources, thus balancing time loss with reliability through dynamic adaptation.
Solution Approach 2:
The system incorporates feedback mechanisms where the UE continuously monitors available resource conditions and adjusts the resource selection window size accordingly. This feedback loop ensures that the window size reflects actual resource availability, preventing excessive time consumption while maintaining sufficient resource availability for coordination messages.
3Reliability
If dynamic resource adjustment is implemented to ensure sufficient available resources, then the reliability improves, but the processing complexity increases
Solution Approach 1:
The patent implements dynamic resource adjustment by modifying the resource selection window size based on available resource conditions. This dynamic approach ensures reliable resource availability for inter-UE coordination messages while managing processing complexity through straightforward conditional adjustments rather than overly complex algorithms.
Solution Approach 2:
The system adjusts the resource selection window size parameter dynamically based on available resource ratios. By changing this key parameter rather than implementing complex multi-parameter optimization, the patent achieves improved reliability while keeping processing complexity manageable through single-parameter adaptation.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for selecting a resource for a transmission of a self-contained inter-UE coordination message, wherein the configuration indicates an initial time interval, a step size for incrementing the initial time interval, and an available resource ratio associated with a resource selection window, and wherein the initial time interval is incremented by the step size until a quantity of available resources within the resource selection window satisfies the available resource ratio. The UE may select, based at least in part on the configuration, the resource for the transmission of the self-contained inter-UE coordination message from the quantity of available resources within the resource selection window. The UE may transmit the self-contained inter-UE coordination message via the selected resource. Numerous other aspects are described.
