Sidelink Signal Transmission Resource Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing methods fail to optimally select or exclude resources for sidelink signal transmission, particularly when channel states vary among multiple antenna units, leading to suboptimal signal quality.
Innovation Solution
A method for transmitting sidelink signals by acquiring measurement information for each antenna unit, determining candidate resources based on RSSI, RSRP, and CBR, and adjusting threshold values to ensure optimal channel state selection, allowing for independent resource management per antenna unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single resource pool is used for all antenna units, then device complexity is reduced, but signal transmission quality deteriorates due to inability to account for per-antenna channel state variations
Solution Approach 1:
The patent divides the resource pool into multiple antenna-specific resource pools, with each pool dedicated to a specific antenna unit. This segmentation allows each antenna unit to independently select resources based on its own channel state measurements (RSSI, RSRP, CBR), thereby improving signal transmission quality while maintaining manageable complexity through structured organization.
Solution Approach 2:
The patent implements local quality by allowing each antenna unit to have its own resource pool configuration and selection criteria tailored to its specific channel conditions. Each antenna unit independently measures channel state and selects resources from its designated pool, enabling optimized performance for each antenna's local environment rather than using a uniform approach for all antennas.
2Ease of operation
If resource selection is centralized for all antenna units, then ease of operation is improved, but adaptability to per-antenna channel conditions deteriorates
Solution Approach 1:
The patent enables each antenna unit to autonomously perform channel state measurements (RSSI, RSRP, CBR) and independently select resources from its own resource pool without centralized coordination. This self-service approach allows each antenna to adapt to its specific channel conditions while maintaining operational simplicity through standardized autonomous selection procedures.
Solution Approach 2:
The patent implements dynamic resource selection where each antenna unit can adaptively adjust its resource choices based on real-time channel state variations. The resource pools are configured to allow flexible selection according to measured channel conditions, enabling each antenna to dynamically respond to changing environmental factors such as interference levels and signal strength.
