Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly 5G NR, face challenges in optimizing antenna tilt angles and beam widths to ensure effective communication, especially in environments with varying user equipment (UE) altitudes.
Innovation Solution
The method involves a UE reporting its altitude and connection metrics to a network node, which then adjusts the antenna tilt angles and beam widths for more suitable beamforming, thereby improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed antenna tilt angle and beam width are used, then the system is simple to operate, but communication effectiveness deteriorates in environments with varying UE altitudes
Solution Approach 1:
The patent implements dynamic adjustment of antenna tilt angles and beam widths based on real-time UE altitude information. The network node receives altitude data from the UE and automatically configures appropriate antenna parameters, transforming the static antenna configuration into a dynamic adaptive system that responds to changing environmental conditions.
Solution Approach 2:
The patent changes the antenna configuration parameters (tilt angle and beam width) based on UE altitude. Different altitude ranges correspond to different optimal parameter settings, allowing the system to adapt to varying propagation conditions by selecting appropriate parameter combinations for each altitude scenario.
2Reliability
If antenna parameters are optimized for specific altitude, then signal quality improves, but the system loses versatility across different altitudes
Solution Approach 1:
The patent creates a universal antenna configuration system that serves multiple altitude ranges. The network node maintains multiple antenna parameter sets and selects the appropriate one based on current UE altitude, enabling a single system to effectively serve diverse altitude scenarios from ground level to elevated positions.
Solution Approach 2:
The patent implements a feedback mechanism where the network node receives UE altitude information and uses it to automatically adjust antenna parameters. This closed-loop feedback system ensures the antenna configuration continuously adapts to the actual operating conditions, maintaining optimal signal quality across varying altitudes.
3Reliability
If manual antenna configuration is used, then device complexity is low, but communication performance deteriorates in varying altitude environments
Solution Approach 1:
The patent enables the system to self-configure antenna parameters automatically based on UE altitude information. The network node autonomously selects and applies appropriate antenna configurations without manual intervention, allowing the system to serve itself in optimizing communication performance across different altitude conditions.
Solution Approach 2:
The patent uses feedback from UE altitude reporting to trigger automatic antenna reconfiguration. When the network node receives altitude updates from UEs, it automatically adjusts the antenna parameters accordingly, creating an automated response mechanism that improves communication performance without requiring manual configuration changes.
