1Productivity
If a resource pool is shared between SL PRS transmission and other SL information, then resource utilization efficiency is improved, but resource allocation complexity increases
Solution Approach 1:
The resource pool is segmented into different resource types (SL PRS resources and other SL information resources) with distinct configurations. The first resource configuration specifically parameters SL PRS resources while the second resource configuration parameters other SL information resources, allowing organized management within the shared pool and reducing allocation complexity through structured division.
Solution Approach 2:
The system dynamically selects between different resource configurations based on positioning requirements and communication conditions. The first device can flexibly choose to use the first resource configuration for SL PRS transmission or the second resource configuration for other SL information, enabling adaptive resource allocation that improves efficiency while managing complexity through conditional selection.
2Reliability
If SL PRS resources are configured in a shared resource pool, then positioning functionality is enhanced, but resource interference increases
Solution Approach 1:
Different regions of the resource pool are assigned different qualities and purposes: SL PRS resources receive dedicated configuration parameters (first resource configuration) optimized for positioning accuracy, while other SL information resources receive separate configuration (second resource configuration). This local differentiation ensures positioning functionality is maintained with high reliability while minimizing interference through specialized resource zones.
Solution Approach 2:
The resource configuration mechanism acts as an intermediary layer between the shared resource pool and the actual transmissions. By introducing configuration parameters that define resource characteristics, the system mediates potential conflicts between SL PRS and other SL information, allowing both to coexist in the shared pool with reduced interference through configured separation.
