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

VSEngineering 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

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidshielding detection time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvebeam switching speedVSAvoidbeam reporting mechanism complexity
Core Design Contradiction:
SpeedVSDevice complexity

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvebeam quality measurement precisionVSAvoidbeam report sending efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

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.

Inventive Principle:
Principle #23Feedback
