Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G wireless communication, especially in high-frequency bands like mmWave, maintaining a strong line-of-sight signal is challenging due to increased attenuation and interference from obstacles, which affects the Quality of Service (QoS) in transportation vehicles using Vehicle-to-Everything (V2X) communications.
Innovation Solution
The method involves determining the attenuation characteristic of a line-of-sight communication channel and adjusting the antenna radiation pattern of user equipment based on this characteristic to enhance signal strength, including adjusting beam width and angle of departure to compensate for attenuation and avoid obstacles, thereby improving communication reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-frequency bands like mmWave are used for 5G wireless communication, then data transmission speed and capacity are improved, but signal attenuation increases and line-of-sight communication becomes more challenging
Solution Approach 1:
The patent applies dynamics by making the antenna radiation pattern adjustable and adaptive rather than fixed. The system dynamically changes beam width and angle of departure based on real-time attenuation characteristics and environmental conditions, allowing the communication system to adapt to varying signal loss conditions in mmWave bands
Solution Approach 2:
The patent changes physical parameters of the antenna system by adjusting the radiation pattern parameters (beam width and angle of departure) according to the determined attenuation characteristics. This parameter adjustment compensates for signal attenuation and maintains effective communication in high-frequency bands
2Reliability
If obstacles are present in the communication path, then signal reliability deteriorates due to interference and blockage, but the system needs to maintain consistent Quality of Service
Solution Approach 1:
The patent applies preliminary action by determining attenuation characteristics and adjusting the antenna radiation pattern in advance before communication degradation occurs. The system proactively adapts to environmental conditions and obstacle positions to maintain reliable communication rather than reacting after signal loss is detected
Solution Approach 2:
The patent implements feedback by continuously determining attenuation characteristics of the line-of-sight communication channel and using this information to adjust the antenna radiation pattern. This closed-loop control ensures consistent Quality of Service by constantly adapting to changing environmental conditions and obstacle interference
3Strength
If the antenna radiation pattern is adjusted to avoid obstacles and compensate for attenuation, then signal strength increases, but system complexity increases due to additional processing requirements
Solution Approach 1:
The patent applies self-service by enabling the user equipment to autonomously determine attenuation characteristics and adjust its own antenna radiation pattern without requiring complex external coordination. The system self-adapts to environmental conditions, reducing the need for complex network-side processing and control
