Solution Overview
Problem
In vehicular communication systems using high frequency bands like mmWave, periodic beam configuration updates are inefficient and can lead to suboptimal QoS due to beam misalignment, especially in fast-changing and congested scenarios, affecting service performance.
Innovation Solution
A method for adjusting processing gain by requesting and receiving processing gain information, which includes determining a beam configuration and predictive QoS, allowing improved determination of antenna system parameters for optimal communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic beam configuration updates are performed in vehicular communication systems using mmWave, then beam alignment can be maintained, but system complexity and update overhead increase especially in fast-changing scenarios
Solution Approach 1:
The patent implements dynamic beam configuration updates based on predicted QoS and channel conditions rather than fixed periodic updates. The system adjusts the update frequency and timing adaptively, performing updates only when predicted to be beneficial for maintaining beam alignment in varying vehicular scenarios
Solution Approach 2:
The system changes the parameter of update frequency dynamically based on predicted QoS metrics and channel conditions. Instead of using a constant periodic update interval, the update timing is adjusted according to real-time assessments of beam alignment quality and predicted future conditions
2Reliability
If frequent beam configuration updates are performed to maintain beam alignment in fast-changing scenarios, then communication reliability improves, but processing overhead and resource consumption increase
Solution Approach 1:
The system performs preliminary QoS prediction and channel condition assessment before executing beam configuration updates. By predicting future QoS metrics and channel states in advance, the system determines optimal update timing beforehand, avoiding unnecessary updates and reducing processing overhead while maintaining communication reliability
3Ease of operation
If processing gain information is not adjusted dynamically, then system operation is simpler, but QoS performance deteriorates in dynamic vehicular environments
Solution Approach 1:
The system implements self-service through automated QoS prediction and processing gain adjustment based on predicted channel conditions. The communication device autonomously determines optimal processing gain values without requiring complex manual configuration or continuous network control signaling, maintaining both simplicity and performance
