Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-vehicle (V2V) communication, existing systems face challenges in managing transmission resource pools effectively, leading to radio signal collisions due to multiple devices using the same resources, and lack efficient methods for selecting optimal transmission resources based on location and congestion.
Innovation Solution
A communication device with a controller and transmitter that identifies its geographical zone and selects a predetermined transmission resource region from a pool based on measurements, congestion levels, and priority of data transmission, to minimize collisions and optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple communication devices use the same transmission resource pool, then resource utilization is improved, but radio signal collisions increase
Solution Approach 1:
The transmission resource pool is segmented into multiple transmission resource regions based on geographical zones. Each communication device identifies its current geographical zone and selects transmission resources from the corresponding region, thereby dividing the shared resource pool into zone-specific subsets that reduce collision probability while maintaining overall resource utilization
Solution Approach 2:
Different transmission resource regions are allocated to different geographical zones, creating local resource quality variations. Devices in each zone access resources locally optimized for that area, improving reliability within each zone while collectively utilizing the entire resource pool across all zones
2Device complexity
If transmission resources are statically allocated, then device complexity is reduced, but adaptability to congestion and location changes deteriorates
Solution Approach 1:
The transmission resource allocation becomes dynamic through automated zone identification and measurement-based selection. Devices automatically adapt their resource selection based on current geographical location and measured congestion levels, eliminating the need for manual configuration while improving adaptability to changing conditions
Solution Approach 2:
Communication devices autonomously perform zone identification, congestion measurement, and transmission resource region selection without external control. This self-service mechanism reduces device complexity by using standardized procedures while achieving high adaptability to local conditions through autonomous decision-making
3Ease of operation
If transmission resources are selected without considering congestion, then ease of operation is improved, but communication reliability deteriorates
Solution Approach 1:
Devices perform preliminary congestion measurements in candidate transmission resource regions before finalizing resource selection. This advance assessment of channel conditions allows devices to choose reliable resources without complex real-time adjustments, maintaining ease of operation while improving communication reliability through informed selection

AI summary
A communication device according to one embodiment includes a controller and a transmitter. The controller is configured to identify a zone that is a geographical section where the communication device is located, and select a predetermined transmission resource region from a plurality of transmission resource regions included in one transmission resource pool associated with the identified zone. The transmitter is configured to transmit a direct radio signal to another communication device by using a resource in the predetermined transmission resource region.
