Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sidelink communication technologies face challenges in efficiently managing sub-channel resources for NR-U and NR sidelink communications, particularly in determining optimal allocations of sub-channel resources based on sidelink resource configuration information.
Innovation Solution
A method is introduced where a terminal device determines the allocation of sub-channel resources by utilizing sidelink resource configuration information, with each sub-channel resource comprising a specific number of interlaces in the frequency domain, enabling efficient transmission or reception of sidelink signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sub-channel resources are allocated based on traditional NR sidelink methods, then compatibility with existing standards is maintained, but spectral efficiency and resource management flexibility are insufficient
Solution Approach 1:
The frequency resources are segmented into interlaces, which are further combined to form sub-channel resources. This segmentation allows flexible allocation of resources based on different communication scenarios while maintaining compatibility with existing NR sidelink standards. The terminal device can determine allocations of sub-channel resources by utilizing sidelink resource configuration information, enabling efficient transmission or reception of sidelink signals.
2Productivity
If more sub-channel resources are allocated to improve spectral efficiency, then resource utilization increases, but the complexity of determining optimal allocations increases
Solution Approach 1:
The network side device performs preliminary configuration of sub-channel resources and provides configuration information to the terminal device. This preliminary action simplifies the terminal device's task to merely determining the allocation based on provided configuration information, reducing the complexity of resource allocation determination while maintaining high spectral efficiency.
