Solution Overview

Problem

In multi-hop vehicle-to-anything (V2X) communication environments, existing technologies face challenges in managing communication load and establishing connections, particularly at intersections, due to increased complexity and potential obstacles, which can hinder efficient data transmission and warning services for vehicles.

Innovation Solution

A wireless communication apparatus and method that determines operation candidate applications based on vehicle driving information to configure a multi-hop communication node tree, setting communication nodes for vehicles approaching from different directions at intersections, and using intermediate nodes to establish connections when direct paths are obstructed, thereby reducing communication load and ensuring data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multi-hop communication is used to extend communication range, then communication coverage is improved, but communication load increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidcommunication load
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent segments the communication network into hierarchical levels (Level 1, Level 2, Level 3 nodes) based on communication hops from the base station. Level 1 nodes communicate directly with the base station, Level 2 nodes communicate with Level 1 nodes, and Level 3 nodes communicate with Level 2 nodes. This segmentation allows extended communication coverage while distributing the communication load across multiple hierarchical levels rather than concentrating it in a single multi-hop path.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If communication nodes are increased to cover intersections, then communication coverage is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidcommunication node configuration
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies local quality by configuring communication nodes with direction-specific attributes. Each communication node is configured with direction information (first direction, second direction, third direction) corresponding to different approach roads at the intersection. This allows the system to manage complex intersection scenarios by treating each directional approach as a distinct local configuration, reducing overall system complexity through localized management.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces direction information as an intermediary element that mediates between multiple communication nodes at the intersection. By using direction information to identify and differentiate communication nodes approaching from different roads, the system simplifies the configuration and management of multiple nodes without requiring complex direct node-to-node identification mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If direct communication paths are used, then communication speed is improved, but reliability decreases due to obstacles

Engineering Contradiction:
Improvecommunication speedVSAvoidcommunication reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-configuring multiple communication paths (direct paths and relay paths through intermediate nodes) before communication obstacles arise. When a direct communication path is blocked by an obstacle, the system can immediately switch to a pre-established relay path through intermediate communication nodes, maintaining communication reliability without requiring real-time path recalculation.

Inventive Principle:
Principle #10Preliminary action
