Beam Report Method for Antenna Panel Shielding Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies fail to timely detect and report beam shielding events in high-frequency communication systems, leading to transmission interruptions due to antenna panel blocking, which is not effectively addressed by existing beam measurement and reporting mechanisms.
Innovation Solution
A method for a terminal to monitor quality parameters of beam links, detect quality loss, and send a beam report to the network when a preset quantity of beam links on an antenna panel experiences quality loss, indicating a shielding event, including indication information about the affected antenna panel, quality parameters, and recommended beam links for switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal uses existing beam measurement and reporting mechanisms, then the beam report can be sent periodically, but the shielding event cannot be detected and reported timely, causing transmission interruption
Solution Approach 1:
The terminal performs preliminary actions by monitoring beam quality parameters continuously and comparing them against threshold values before actual transmission interruption occurs. The shielding detection mechanism is activated in advance by detecting quality degradation trends, allowing the terminal to report shielding events before they cause complete transmission failure, thus preventing time loss in beam switching.
2Speed
If the terminal switches to alternative beam links quickly, then transmission can be maintained, but the existing beam reporting mechanism does not support fast shielding detection and reporting
Solution Approach 1:
The patent changes the parameter threshold for beam quality monitoring from standard periodic reporting thresholds to shielding-specific threshold values. By adjusting these parameters, the terminal can detect shielding events faster and trigger immediate beam switching without requiring complex new reporting protocols, thus achieving fast beam switching with minimal mechanism complexity.
3Measurement precision
If the terminal monitors beam quality parameters continuously, then shielding events can be detected timely, but the existing periodic reporting mechanism does not enable this continuous monitoring
Solution Approach 1:
The terminal implements feedback by continuously monitoring beam quality parameters and comparing them against predefined thresholds. When the quality parameter exceeds the shielding threshold, the terminal immediately triggers a beam report without waiting for the next periodic reporting cycle. This feedback mechanism maintains measurement precision while improving reporting efficiency by eliminating unnecessary periodic reports and enabling event-driven communication.
