Solution Overview

Problem

In vehicle-to-vehicle (V2V) communication, the increased number of terminals receiving and transmitting safety messages leads to higher traffic and resource wastage, necessitating a method to efficiently allocate radio resources.

Innovation Solution

A method and apparatus for resource allocation using location information and additional situation information from sensors and CCTV, allowing the base station to dynamically allocate resources based on the terminal's location and situation, minimizing resource collisions between neighboring terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resources are allocated without considering location information, then the allocation process is simple, but resource collision and wastage increase

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidallocation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the service area into multiple zones based on location information, and assigns different resource pools to each zone. This segmentation prevents resource collision between neighboring terminals while maintaining simple allocation within each zone, resolving the contradiction between reliability and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different resource allocation strategies to different zones based on their location characteristics. Each zone receives resources tailored to its specific spatial requirements and traffic patterns, improving overall allocation efficiency without requiring a completely complex unified system.

Inventive Principle:
Principle #3Local quality

2Loss of energy

If location information is collected and used for resource allocation, then resource wastage is reduced, but system complexity increases

Engineering Contradiction:
Improveresource wastageVSAvoidsystem complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The base station performs preliminary actions by pre-dividing the service area into zones and pre-assigning resource pools to each zone before actual communication occurs. This preliminary organization allows efficient resource allocation based on location information without adding significant complexity to the real-time allocation process.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If dynamic resource allocation based on situation information is implemented, then adaptability improves, but processing complexity increases

Engineering Contradiction:
Improvesituation adaptation capabilityVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic resource allocation by allowing the base station to adjust resource assignments based on real-time situation information such as terminal speed and location changes. The system dynamically adapts resource allocation to current conditions while maintaining a structured zone-based framework that limits processing complexity.

Inventive Principle:
Principle #15Dynamics
