Sidelink Resource Set Reporting for Efficient UE Resource Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication systems lack efficient resource allocation mechanisms, leading to suboptimal resource selection by transmitting UEs without considering the receiving UE's requirements, resulting in inefficient resource utilization.
Innovation Solution
A coordination scheme is introduced where a first UE indicates information to form a resource set report, including configurations of sensing resource pools, parameters, and formats, allowing a second UE to select resources that better align with both UEs' needs, enhancing resource selection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resource allocation is performed without efficient mechanisms in sidelink communication, then device complexity is reduced, but spectral efficiency deteriorates and power consumption increases
Solution Approach 1:
The patent applies preliminary action by having the receiving device perform sensing on the resource pool before resource allocation, identifying suitable resources in advance based on sensing parameters. This pre-selection of resources improves spectral efficiency by avoiding conflicts and reduces power consumption by eliminating the need for repeated sensing and resource selection attempts.
Solution Approach 2:
The patent implements feedback through the resource set report mechanism, where the receiving device provides feedback to the transmitting device about suitable resources identified through sensing. This feedback loop enables the transmitting device to allocate resources efficiently, improving spectral efficiency while reducing power consumption by avoiding unnecessary transmissions on unsuitable resources.
2Productivity
If resource allocation is performed without efficient mechanisms, then device complexity is reduced, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the resource pool into multiple resource sets based on sensing parameters, and further segmenting the allocation process into distinct phases: sensing, resource set formation, and resource allocation. This segmentation improves resource allocation efficiency by organizing resources systematically while managing complexity through structured procedures.
Solution Approach 2:
The patent introduces the resource set report as an intermediary mechanism that facilitates coordination between transmitting and receiving devices. The report acts as a mediator carrying information about suitable resources, improving resource allocation efficiency while reducing direct coordination complexity between devices through standardized information exchange.
3Measurement precision
If resource selection is performed without sensing parameters, then device complexity is reduced, but resource selection quality deteriorates
Solution Approach 1:
The patent applies preliminary action by performing sensing operations before resource selection, where the receiving device measures the resource pool using sensing parameters to identify suitable resources in advance. This preliminary sensing improves resource selection quality by ensuring resources are selected based on actual channel conditions rather than random selection, while managing sensing complexity through structured measurement procedures.
Solution Approach 2:
The patent implements parameter changes by using multiple sensing parameters (such as reference signal received power thresholds, resource pool configurations) to characterize and evaluate resources. These parameter-based evaluations improve resource selection quality by providing quantitative criteria for resource selection, while managing complexity through standardized parameter sets that can be configured and reused.
