Terminal SL PRS Resource Configuration for Flexible Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in sidelink communication systems is determining the appropriate resource unit for sidelink positioning reference signal (SL PRS) resource exclusion during resource selection, particularly in the second mode where a single slot resource is used as a unit, which can lead to inefficiencies and potential interference.
Innovation Solution
A method for determining configuration information to configure sidelink positioning reference signal (SL PRS) resources in a resource pool, allowing for flexible selection of resource units for exclusion, thereby improving resource allocation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single slot resource is used as a resource unit for SL PRS resource exclusion, then the resource selection process is simplified, but resource allocation efficiency deteriorates and interference increases
Solution Approach 1:
The patent segments the resource pool into multiple resource units, where each resource unit can contain one or more slot resources. This segmentation allows the terminal device to perform resource exclusion at the resource unit level rather than at the individual slot level, thereby improving resource allocation efficiency while maintaining operational simplicity. The resource unit acts as a higher-level abstraction that groups multiple slot resources together.
2Ease of operation
If a single slot resource is used as a resource unit for SL PRS resource exclusion, then the resource selection process is simplified, but interference between resources increases
Solution Approach 1:
By segmenting resources into units that can encompass multiple slot resources, the patent enables more effective interference management. The terminal device can exclude entire resource units that may cause interference, rather than dealing with individual slot resources, thus reducing the complexity of interference avoidance while improving the effectiveness of interference mitigation.
3Productivity
If flexible resource unit selection is implemented for SL PRS resource exclusion, then resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal resource unit structure that can accommodate different configurations of slot resources within a single framework. The resource unit design is multi-functional, allowing it to represent various resource aggregation patterns (e.g., different numbers of slots per unit, different resource types within units) without requiring fundamentally different mechanisms. This universality reduces device complexity while maintaining flexibility and efficiency.
