Correlating Downlink and Uplink Measurement Data for Link Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication network technologies face challenges in accurately determining link coverage problems, particularly uplink coverage issues, due to reliance on downlink measurement data alone, which fails to analyze or locate unbalanced uplink and downlink coverage problems effectively.
Innovation Solution
A method that correlates downlink and uplink measurement data using a time window, user equipment identifier, or cell identifier to comprehensively analyze link coverage problems, enabling accurate determination of radio link coverage issues by considering both downlink and uplink situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only downlink measurement data is used for analysis, then the analysis process is simple, but the accuracy of determining link coverage problems is insufficient
Solution Approach 1:
The patent combines downlink measurement data and uplink measurement data into a unified analysis framework. By merging these two types of measurement data and correlating them through time windows and identification information, the system achieves comprehensive link coverage problem determination that accurately identifies both downlink and uplink coverage issues, resolving the limitation of using only downlink data.
2Measurement precision
If downlink and uplink measurement data are correlated using multiple parameters (time window, UE identifier, cell identifier), then the accuracy of problem localization is improved, but the processing complexity increases
Solution Approach 1:
The patent segments the data correlation process into distinct functional modules: time window determination module, identification information matching module, and coverage problem determination module. This segmentation allows the system to handle complex multi-parameter correlation by breaking it down into manageable steps, where each module processes specific aspects of the correlation independently, reducing overall processing complexity while maintaining high localization accuracy.
3Measurement precision
If a time window is used for correlating measurement data, then the correlation accuracy is improved, but the processing time increases
Solution Approach 1:
The patent applies partial action by using a time window that covers only the necessary correlation range rather than analyzing all possible time periods. The time window is configured to include sufficient historical measurement data for accurate correlation while excluding unnecessary extended periods, thus achieving good correlation accuracy without excessive processing time consumption.

AI summary
A method, apparatus, and system for determining link coverage problem are disclosed. Downlink measurement data and uplink measurement data are correlated to perform analysis, so that determining of a link coverage problem no longer depends only on the downlink measurement data, but depends on a combination of the downlink measurement data and the uplink measurement data. In this way, the determining of the link coverage problem is more accurate, which facilitates subsequent use of a correct solution.
