Solution Overview

Problem

In vehicle platooning, existing systems face challenges in reasonably scheduling communication resources among group members and group heads, leading to resource conflicts and interference.

Innovation Solution

A method where group members report their location information to group heads, allowing the group heads to assign resources based on this information, ensuring that distant terminals reuse resources and proximal terminals use different resources, thereby reducing interference and enabling efficient resource scheduling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the group head uniformly schedules all communication resources, then the scheduling process is simple, but the resource scheduling becomes unreasonable and causes conflicts

Engineering Contradiction:

Improvescheduling process complexityVSAvoidresource scheduling reasonability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the uniform resource scheduling approach into segmented, location-based scheduling. Group members report their location information to the group head, which then segments the resource allocation based on spatial distribution. This allows distant terminals to reuse resources while proximal terminals use different resources, eliminating conflicts without overly complicating the scheduling process.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by differentiating resource allocation based on the local location of each group member. Instead of uniform scheduling, the system assigns resources according to the specific spatial characteristics of each terminal within the platoon, enabling reasonable scheduling that accounts for local conditions and reduces interference.

Inventive Principle:

Principle #3Local quality

2Productivity

If distant terminals reuse the same resource, then resource utilization efficiency improves, but interference between terminals increases

Engineering Contradiction:

Improveresource utilization efficiencyVSAvoidinterference between terminals

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a spatial dimension to resource scheduling by considering the location information of group members. Terminals are assigned resources based on their spatial coordinates, allowing distant terminals to reuse resources while proximal terminals use different resources. This dimensional approach to scheduling simultaneously achieves high resource utilization efficiency and minimizes interference by leveraging spatial separation.

AI summary

An information reporting method applied to a first terminal includes: reporting first location information to a second terminal. The first terminal is a group member in a first group, and the second terminal is a group head in the first group.
