Transceiver Resource Selection Using Dual Threshold Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sensing scheme in wireless communication systems, particularly in NR V2X, fails to accurately segregate and prioritize resources, leading to suboptimal resource selection and potential interference due to the inability to distinguish between resource quality and occupancy status.
Innovation Solution
A transceiver configured to perform long-term sensing by decoding control data and power sensing, allowing for precise estimation of resource usability and quality, and scheduling transmissions based on this information, while also utilizing multiple threshold values for prioritizing resources based on different priority classes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the transceiver uses a single threshold value for resource selection, then the device complexity is reduced, but the resource selection accuracy deteriorates because it cannot distinguish between resource quality and occupancy status
Solution Approach 1:
The patent segments the resource selection process into two distinct stages: (1) occupancy detection using a first threshold to identify resources currently in use, and (2) quality evaluation using a second threshold to assess resource suitability. This segmentation allows the transceiver to separately handle occupancy status and resource quality, improving measurement precision without overwhelming complexity
Solution Approach 2:
The patent changes the threshold parameter from a single fixed value to multiple adjustable values (first threshold for occupancy, second threshold for quality). This parameter change enables the system to adapt to different resource conditions and transmission requirements, achieving higher accuracy in resource selection by evaluating both occupancy and quality dimensions
2Quantity of substance
If the transceiver increases the threshold value to find more free resources, then the quantity of available resources increases, but the resource quality deteriorates because lower quality resources are included
Solution Approach 1:
The patent segments resources into different categories based on their evaluation results: resources passing the first threshold are identified as available (quantity), while resources passing the second threshold are identified as high quality (precision). This segmentation allows the system to report both the quantity of available resources and the quality metric separately, resolving the contradiction between finding more resources and maintaining quality
Solution Approach 2:
The patent uses two different threshold parameters (first threshold for occupancy detection, second threshold for quality assessment) to evaluate resources. By changing and adjusting these threshold parameters independently, the system can control the trade-off between quantity and quality of selected resources, ensuring that higher threshold values for quantity do not automatically degrade quality metrics
3Reliability
If the transceiver performs long-term sensing to accurately estimate resource usability, then the resource selection reliability is improved, but the time consumption increases due to extended sensing duration
Solution Approach 1:
The patent extracts and utilizes decoded control data from the channel to obtain utilization information about resources. By taking out this pre-existing information from control messages and using it for sensing, the system achieves reliable resource selection without requiring extended sensing periods, thus reducing time loss while maintaining or improving reliability
Solution Approach 2:
The patent performs preliminary decoding of control data to obtain utilization information before the actual resource selection process. This preliminary action provides advance knowledge about resource occupancy patterns, enabling the transceiver to make more reliable selections faster, thereby improving reliability while reducing the time needed for the sensing and selection process
