Problem

Current 5G communication systems face challenges in providing reliable and efficient data transmission for vehicle communication services, particularly in varying channel environments and service types, leading to resource congestion, latency, and power consumption issues.

Innovation Solution

A method for dynamically changing radio paths based on channel environment and service type, involving configuration information for terminals and base stations to determine and request uplink resources, utilizing parameters like channel measurement thresholds, packet priority, and service priority to optimize resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed radio path is used for vehicle communication, then the system structure is simple, but the data transmission reliability deteriorates in varying channel environments

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidradio path management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic radio path selection by enabling terminals to switch between first radio paths (direct terminal-to-terminal communication) and second radio paths (terminal-to-base station-to-terminal communication) based on real-time channel conditions. The base station configures path change conditions and terminals execute path switching when conditions are met, transforming the static communication path into a dynamic adaptive system that responds to environmental changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback mechanism where terminals monitor channel conditions and report to the base station, which then determines whether to trigger radio path changes. The base station configures path change conditions and receives feedback from terminals about channel state, enabling closed-loop control that continuously optimizes the radio path selection based on actual communication quality.

Inventive Principle:
Principle #23Feedback

2Reliability

If radio path changes are performed frequently to adapt to channel variations, then the data transmission reliability is improved, but the latency increases due to path switching overhead

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidpath switching latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the base station pre-configure radio path change conditions and parameters before they are needed. The base station provides configuration information including path change triggers and procedures in advance, so that when channel conditions deteriorate, the terminal can immediately execute the pre-configured path switching without delay for real-time negotiation or configuration.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If conservative radio path selection is used to minimize changes, then the system stability is maintained, but the adaptability to different service types deteriorates

Engineering Contradiction:
Improveservice type adaptabilityVSAvoidradio path stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements local quality by configuring different radio path change conditions and strategies for different service types and channel locations. The base station can specify different path change thresholds, triggers, and procedures tailored to specific service requirements (e.g., low-latency services may trigger path changes more aggressively than high-throughput services), allowing each service to optimize its performance according to its specific needs while maintaining overall system stability.

Inventive Principle:
Principle #3Local quality
