Solution Overview

Problem

Current 5G communication systems lack an efficient method for managing multicarrier-based vehicle-to-everything (V2X) communication services, particularly in sharing V2X service carrier information between terminals and base stations, which hinders effective resource management and load balancing.

Innovation Solution

A method where a terminal and a base station exchange system information including multiple V2X carriers, frequencies, and pools, with the terminal transmitting sidelink user equipment information indicating interest carriers and capability for simultaneous transmission and reception, enabling efficient resource management and handover processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multicarrier-based V2X communication is implemented, then communication capacity and service support are improved, but resource management complexity and information sharing overhead increase

Engineering Contradiction:
ImproveV2X communication capacityVSAvoidResource management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments V2X communication resources by dividing them into multiple carriers, each with dedicated resource pools for transmission and reception. This segmentation allows independent management of each carrier's resources, reducing overall management complexity while maintaining high communication capacity through parallel operations on multiple carriers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension for resource management by implementing carrier-specific resource pools and adding carrier indication fields to uplink grants. This dimensional extension allows the system to manage multiple carriers simultaneously with distinct resource allocations, resolving the contradiction between increased capacity and management complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple V2X carriers are supported, then service versatility is improved, but information exchange overhead between terminal and base station increases

Engineering Contradiction:
ImproveV2X service versatilityVSAvoidInformation exchange overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates a universal framework where a single uplink grant message structure can indicate multiple carriers through carrier indication fields. This multi-functional approach allows the same signaling mechanism to handle resource allocation across different carriers, reducing information overhead while maintaining service versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the parameter representation by using compact carrier indication fields within uplink grants rather than separate signaling for each carrier. This parameter optimization reduces the amount of information that needs to be exchanged while still supporting multiple carriers and diverse V2X services.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If carrier-specific resource pools are implemented, then resource management efficiency is improved, but system configuration complexity increases

Engineering Contradiction:
ImproveResource management efficiencyVSAvoidSystem configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring carrier-specific resource pools for each V2X carrier before actual communication occurs. This advance configuration allows the system to efficiently manage resources during operation without real-time negotiation, improving resource management efficiency while the configuration complexity is handled once during system setup.

Inventive Principle:
Principle #10Preliminary action
