D2D Resource Pool Segmentation to Reduce Selection Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in efficiently managing scenarios where devices with different types of resource selection mechanisms for D2D transmissions coexist in the same resource pool, leading to increased collision probabilities and degraded system performance.
Innovation Solution
A resource pool is divided into multiple subsets, each associated with a specific type of selection mechanism, and prioritization rules are applied to steer resource selection based on the type of mechanism used by the wireless communication device, ensuring that devices with higher collision risk are directed to specific parts of the pool.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of selection mechanisms are allowed to coexist in the same resource pool, then device complexity and adaptability are improved, but collision probability increases and system performance degrades
Solution Approach 1:
The resource pool is divided into multiple subsets, where each subset is associated with a specific type of selection mechanism. This segmentation isolates different selection mechanisms into separate resource domains, preventing interference and collisions between them while maintaining the diversity of selection mechanisms in the system.
Solution Approach 2:
Different subsets of the resource pool are assigned different characteristics based on the selection mechanism type. Each subset has localized resource allocation rules and priorities tailored to its associated selection mechanism, ensuring optimal performance for each mechanism type without affecting others.
2Use of energy by moving object
If autonomous resource allocation is used to reduce network interaction and power consumption, then power efficiency is improved, but resource selection optimization deteriorates
Solution Approach 1:
The wireless communication device autonomously determines its own resource selection mechanism type and automatically applies the corresponding prioritization rules without network assistance. The device self-configures its resource selection strategy based on its capabilities and conditions, reducing network interaction while maintaining optimized resource selection.
Solution Approach 2:
The system changes the parameter of resource pool configuration to include subset divisions and prioritization rules that adapt to different selection mechanism types. These parameter changes enable autonomous devices to efficiently select resources by following predefined rules associated with their specific mechanism type.

AI summary
A resource pool for selection of radio resources for D2D transmissions by wireless communication devices is divided into multiple subsets (S1, S2, S3) of radio resources which are each associated with at least one of multiple types of selection mechanisms. Depending on which of the multiple types of selection mechanisms is applied by a wireless communication device for selection of radio resources for D2D transmissions, the wireless communication device performs prioritization of the subsets (S1, S2, S3). Based on the prioritization of the subsets (S1, S2, S3), the wireless communication device selects at least on radio resource from the resource pool. Further, the wireless communication device performs one or more D2D transmissions on the selected at least one radio resource.
