Sidelink Positioning Resource Prioritization for Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing sidelink positioning operations due to conflicts between sidelink and non-sidelink operations, leading to resource allocation inefficiencies and potential interference.
Innovation Solution
The implementation of priority values for sidelink positioning operations, allowing user equipment (UE) to select and reserve resources based on these priorities, thereby resolving conflicts and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resources are allocated for sidelink positioning operations without priority-based management, then resource availability for positioning is maintained, but resource conflicts and interference with other operations occur
Solution Approach 1:
The patent applies parameter changes by introducing priority values as a new parameter to characterize different sidelink operations. This allows the system to differentiate between positioning operations and other sidelink communications, enabling dynamic resource allocation decisions based on operation priority levels rather than treating all operations equally.
Solution Approach 2:
The patent implements dynamics by making resource allocation adaptive and dynamic through priority-based mechanisms. The UE can dynamically select resources for positioning operations based on the priority values assigned to different operations, allowing the system to respond to changing conditions and resolve conflicts in real-time rather than using static resource allocation.
2Productivity
If priority values are assigned to sidelink positioning operations, then resource conflicts are resolved and positioning efficiency improves, but system complexity increases
Solution Approach 1:
The patent uses parameter changes by assigning numerical priority values to different sidelink operations, transforming the resource allocation problem into a parameter-based decision process. This simplifies the complexity by providing a clear, quantifiable metric for resource selection rather than requiring complex conflict resolution logic.
Solution Approach 2:
The patent applies self-service by enabling the UE to autonomously perform resource selection for positioning operations based on pre-configured or dynamically provided priority values. The UE independently resolves resource conflicts without requiring complex network intervention or centralized coordination, reducing overall system complexity while maintaining positioning efficiency.

AI summary
Sidelink (SL) positioning of user equipments (UEs) is supported by assigning priority values to SL positioning operations, e.g., transmission or reception of SL positioning reference signals (PRS). The priority value, for example, may be (pre-)configured or provided to the physical (PHY) layer from higher layers. The UE selects resources for the SL positioning operations based on at least the priority value. The UE may reserve resources for the SL positioning operations, for example, using Layer 1 (L1) and/or Layer 2 (L2) control operations or by transmitting an indication that other UEs are to avoid using the resources. The priority values for the SL positioning operations may be used to resolve in-device conflicts, such as when the SL positioning operations conflict with other sidelink or non-sidelink operations.
