Beam Detection Method for Downlink Quality Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam detection methods in communication technologies lack detailed information about downlink beam quality, making it difficult for network devices to improve communication with user equipment.
Innovation Solution
A method where user equipment receives beam quality monitoring signals from a network device, determines signal qualities, and generates detailed detection reports indicating beam qualities that do or do not meet specific thresholds, allowing the network device to adjust beam usage accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user equipment reports only that all downlink beams are unavailable when beam quality is poor, then the reporting format is simple, but the network device receives less information and cannot effectively improve communication
Solution Approach 1:
The detection report is segmented into multiple fields: a first field indicating whether beam quality meets a first threshold, and a second field indicating whether beam quality meets a second threshold. This segmentation allows detailed beam quality information to be conveyed in an organized manner, resolving the contradiction between information completeness and report complexity.
Solution Approach 2:
The patent introduces multiple threshold parameters (first threshold and second threshold) to evaluate beam quality. By changing the evaluation parameters from a single binary judgment to a multi-level assessment, the system can provide richer information about beam quality while maintaining clear report formatting.
2Reliability
If the network device uses multiple downlink beams for PDCCH transmission, then the spatial diversity gain is improved, but the complexity of beam management and quality assessment increases
Solution Approach 1:
The beam quality monitoring is segmented into multiple independent evaluation dimensions (first threshold assessment and second threshold assessment). This allows the network device to manage multiple beams systematically by evaluating each beam's quality against multiple criteria, reducing the overall complexity of beam management while maintaining high reliability.
Solution Approach 2:
The user equipment provides feedback in the detection report about which beams meet which thresholds. This feedback mechanism enables the network device to automatically identify suitable beams for PDCCH transmission without complex manual assessment, improving reliability while simplifying the monitoring process.
