Sidelink Positioning Resource Duration for Efficient UE Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication systems face challenges in efficiently managing resource allocation for relative positioning between user equipment (UEs), leading to potential resource waste and reduced utilization due to continuous allocation without consideration of duration and network load.
Innovation Solution
Implementing a method for resource processing that includes sending and receiving resource configuration information with available duration details for relative positioning resources, allowing for timely reclamation and optimized allocation based on load and positioning accuracy, thereby reducing waste and improving resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous resource allocation is used for relative positioning, then positioning availability is improved, but resource waste increases
Solution Approach 1:
The patent implements dynamic resource allocation where the network device configures positioning resources with specific available durations rather than continuous allocation. The UE releases resources after the configured duration expires, creating a dynamic on-demand resource usage pattern that balances availability with efficiency.
Solution Approach 2:
The patent changes the parameter of resource allocation from continuous to time-limited by introducing the 'available duration' parameter. This parameter controls how long positioning resources remain allocated to the UE, allowing the system to optimize between availability and resource efficiency by adjusting duration based on positioning requirements.
2Measurement precision
If long duration resource allocation is used, then positioning accuracy is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts resource allocation duration based on actual positioning needs. The network device configures appropriate available durations considering positioning accuracy requirements and current network load, allowing resources to be allocated long enough for accurate positioning while being released promptly to maintain high utilization efficiency.
3Reliability
If resource allocation is not reclaimed timely, then positioning reliability is maintained, but resource waste increases
Solution Approach 1:
The patent applies preliminary action by configuring the available duration parameter in advance. The UE is notified of the exact duration for which positioning resources are allocated, enabling it to automatically release resources at the appropriate time without requiring continuous monitoring or manual intervention, thus preventing resource waste while maintaining reliability.
Solution Approach 2:
The system implements feedback through the resource configuration mechanism where the network device specifies the available duration and the UE confirms resource usage within this timeframe. This feedback loop ensures resources are allocated appropriately and released timely, balancing reliability with efficiency.

AI summary
A method for resource processing is performed by a base station which sends resource configuration information. The resource configuration information at least includes available duration information which indicates the available duration for the relative positioning resource for relative positioning between UEs. A method for resource processing, performed by a user equipment (UE), includes receiving the resource configuration information indicating an available duration of a relative positioning resource for relative positioning between UEs.
