Solution Overview

Problem

In wireless communication systems, the correlation between location information and measurement results is often low due to timing discrepancies, leading to inaccurate indication of the measurement location of user equipment, which hinders network optimization.

Innovation Solution

A method and apparatus for evaluating the correlation between location information and measurement results by determining the time interval or distance section between the acquisition times, and transmitting reporting messages to a base station only when the correlation is high, ensuring accurate location information is reported with the measurement results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If location information is acquired at a different time than measurement result acquisition, then the acquisition timing is flexible and device operation is simplified, but the correlation between location information and measurement result decreases, leading to inaccurate measurement location indication

Engineering Contradiction:
Improveacquisition timing flexibilityVSAvoidmeasurement location indication accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system introduces a correlation evaluation mechanism that provides feedback on the quality of location information. The user equipment evaluates the correlation between location information and measurement results, and only reports location information when the correlation exceeds a threshold, ensuring accurate measurement location indication while maintaining operational flexibility

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts the reporting behavior based on the evaluated correlation value. When correlation is high, location information is reported; when correlation is low, reporting is suppressed. This dynamic approach resolves the contradiction by adapting the system behavior to the actual correlation quality between location and measurement data

Inventive Principle:
Principle #15Dynamics

2Productivity

If location information is always reported with measurement results, then network optimization can be performed, but unnecessary location information transmission occurs when correlation is low, wasting network resources

Engineering Contradiction:
Improvenetwork optimization effectivenessVSAvoidnetwork resource waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

Instead of always reporting location information (excessive action) or never reporting (insufficient action), the system applies partial action by reporting location information only when the evaluated correlation exceeds a predefined threshold. This selective reporting ensures network optimization effectiveness while avoiding waste of network resources on low-correlation data

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Provided is a method for reporting performed by user equipment in a wireless communication system. The method comprises: obtaining an estimation result from a first point in time; obtaining location information from a second point in time; determining a correlation between the location information and the estimation result; and transmitting to a base station a report message including the estimation result. When the location information is determined to have a high correlation to the estimation result through a correlation validity evaluation, the method further comprises transmitting the location information to the base station.
