Solution Overview
Problem
Existing cellular network positioning technologies are inadequate for sidelink positioning, particularly in out-of-coverage scenarios and high-speed environments, lacking a resource configuration solution adapted to sidelink positioning needs.
Innovation Solution
A method and apparatus for resource configuration that selects and transmits sidelink-positioning reference signals (SL-PRS), positioning data, and positioning control channels from dedicated or non-dedicated resource pools, optimizing channel allocation to support sidelink positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular network positioning technologies are used for sidelink positioning, then positioning functionality can be provided, but the positioning performance is inadequate in out-of-coverage scenarios and high-speed environments
Solution Approach 1:
The patent segments the positioning functionality into separate channels: positioning control channels for scheduling information, positioning data channels for measurement data, and positioning reference signal channels for actual positioning signals. This segmentation allows each channel to be optimized independently for sidelink positioning requirements, improving overall reliability and adaptability.
Solution Approach 2:
The patent creates a universal resource pool configuration that can serve multiple purposes: dedicated positioning resource pools for positioning-specific operations and non-dedicated resource pools for general sidelink communication. This multi-functionality enables the system to adapt to both out-of-coverage and high-speed scenarios while maintaining positioning reliability.
2Productivity
If resource pools are configured for sidelink positioning channels, then transmission efficiency is improved, but channel collision probability increases without proper resource management
Solution Approach 1:
The patent implements dynamic resource allocation within the resource pools, where resources can be flexibly assigned and reconfigured based on current positioning needs and channel conditions. This dynamic approach allows the system to maintain high transmission efficiency while adapting to varying traffic patterns and reducing collision probability through intelligent resource management.
Solution Approach 2:
The patent incorporates feedback mechanisms through positioning control channels that provide scheduling information and resource allocation decisions. This feedback loop enables the system to monitor channel usage, detect potential collisions, and dynamically adjust resource allocation to maintain transmission efficiency while minimizing collision probability.
