Sidelink Resource Allocation Using Reliability-Aware Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication technologies face challenges in achieving reliable resource allocation and efficient power management, as resource availability reports from monitoring devices may vary due to differing channel characteristics and interference, leading to suboptimal communication performance.
Innovation Solution
A transmitting device combines its own resource availability information with a report from a monitoring device to enhance sidelink communication reliability, selecting the most suitable resource allocation technique based on parameters like channel busy ratio and packet delay budget.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a UE uses resource availability reports from monitoring devices for sidelink resource allocation, then resource allocation efficiency is improved, but communication reliability deteriorates due to varying channel characteristics and interference
Solution Approach 1:
The patent combines multiple resource availability reports from different monitoring devices to create a more reliable resource allocation decision. By merging information from multiple sources rather than relying on a single report, the system achieves both improved resource allocation efficiency and enhanced communication reliability through diversified input data.
Solution Approach 2:
The patent dynamically adjusts resource allocation parameters based on measured communication reliability metrics. When reliability falls below thresholds, the system changes parameters such as selecting different resource pools or adjusting transmission power, thereby adapting to varying channel conditions while maintaining efficient resource utilization.
2Loss of time
If a UE autonomously selects resources from sidelink resource pools, then communication latency is reduced, but resource allocation reliability deteriorates due to lack of coordination
Solution Approach 1:
The patent performs preliminary resource availability assessments by monitoring devices before actual data transmission occurs. This advance preparation allows UEs to quickly select resources with minimal latency while maintaining reliability through pre-validated resource selections that have been checked for availability and suitability.
Solution Approach 2:
The patent implements feedback mechanisms where monitoring devices report resource availability and transmission outcomes are fed back to adjust future resource selections. This continuous feedback loop enables autonomous UEs to make reliable resource allocation decisions without coordination overhead, reducing latency while maintaining high reliability through learned patterns and real-time adjustments.

AI summary
Examples of the disclosure relate to generating a packet for transmission over a sidelink resource pool and transmitting the packet to a second UE on a set of sidelink resources of the sidelink resource pool. The set may be selected based on a resource selection procedure of a plurality of resource selection procedures. The resource selection procedure may be selected based at least in part on one or more utilization parameters corresponding to one or more resources of the sidelink resource pool. Other examples, and features are also claimed and described.
