Solution Overview

Problem

Current wireless communication systems face challenges in supporting reliable vehicle-to-everything (V2X) services, particularly in managing channel busy ratios (CBR) and resource pool configurations to ensure continuous and reliable communication for vehicles.

Innovation Solution

A method and terminal configuration for V2X services that involve receiving threshold information for reporting CBR, measuring the CBR, and identifying whether a reporting condition is satisfied, allowing for the reporting of the measured CBR to ensure efficient resource allocation and service continuity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If CBR measurement and reporting mechanisms are implemented for V2X services, then resource allocation efficiency is improved, but system complexity and overhead increase

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent changes the parameter of CBR reporting by introducing threshold-based triggering mechanisms. Instead of continuous or periodic reporting, the system only triggers CBR reports when the measured CBR exceeds or falls below predefined thresholds. This parameter change reduces unnecessary reporting while maintaining effective resource allocation monitoring, thus improving productivity without proportionally increasing device complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms where CBR measurements are continuously monitored and compared against thresholds, triggering reports only when conditions warrant attention. This feedback approach ensures resource allocation efficiency is maintained through timely information while avoiding the overhead of constant reporting, effectively balancing productivity improvement with complexity management.

Inventive Principle:
Principle #23Feedback

2Reliability

If frequent CBR reporting is performed to ensure service continuity, then reliability is improved, but network overhead and energy consumption increase

Engineering Contradiction:
Improveservice continuityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent employs periodic CBR measurement with event-triggered reporting based on threshold conditions. Instead of continuous reporting, the system periodically measures CBR and only reports when thresholds are crossed, creating a rhythm of measurement and selective reporting. This ensures service continuity through regular monitoring while significantly reducing energy consumption compared to continuous reporting mechanisms.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The terminal autonomously determines when CBR reporting is necessary by comparing measured values against thresholds without requiring constant network intervention. This self-service approach ensures service continuity through reliable monitoring while minimizing energy consumption by avoiding unnecessary reporting transmissions, allowing the system to serve itself efficiently.

Inventive Principle:
Principle #25Self-service

3Reliability

If comprehensive resource pool monitoring is implemented, then service reliability is improved, but processing complexity and signaling overhead increase

Engineering Contradiction:
Improveservice reliabilityVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts only the essential information needed for resource allocation decisions by implementing threshold-based CBR reporting. Instead of reporting all measured data, the system extracts and reports only when CBR values cross significant thresholds, reducing signaling overhead while maintaining service reliability. This selective extraction eliminates unnecessary information transmission while preserving critical resource status data.

Inventive Principle:
Principle #2Taking out (Extraction)
