Timing Error Group Reporting for Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, timing errors caused by delays in signal processing from baseband processors to antenna radio frequency ports affect positioning accuracy, which existing methods fail to adequately address.
Innovation Solution
The method involves a positioning management function network element receiving timing error group information from terminal devices or transmission and reception points to correct for these errors, improving positioning accuracy by transmitting and processing first indication information that includes timing error group data.

Engineering Contradiction Analysis
1Measurement precision
If timing error group information is reported and processed, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The timing error is segmented into discrete timing error group (TEG) values, where each TEG represents a specific time delay range. The system divides the continuous timing error into quantized groups that can be efficiently reported and processed, reducing the complexity of handling continuous timing variations while maintaining positioning accuracy.
Solution Approach 2:
The system changes the parameter representation from continuous timing error to discrete TEG indices. By transmitting TEG information instead of raw timing error values, the system simplifies data processing and reduces computational complexity while preserving the essential timing characteristics needed for accurate positioning.
2Measurement precision
If timing error compensation is implemented, then positioning precision is enhanced, but processing time increases
Solution Approach 1:
The system performs preliminary action by pre-calculating and pre-reporting timing error group information before positioning calculations are performed. The TEG data is prepared in advance and made available for use in positioning computations, eliminating the need for real-time timing error analysis and reducing processing time during actual positioning operations.
Solution Approach 2:
The system uses timing error group information as a simplified copy or representation of the actual timing error characteristics. Instead of processing the full complexity of raw timing error data, the system works with compressed TEG representations that capture the essential timing behavior, enabling faster processing while maintaining positioning precision.

AI summary
A method for reporting a timing error is performed by a location management function (LMF) network element. The method includes: receiving first indication information transmitted by a transmission end, wherein the first indication information indicates timing error group (TEG) information of the transmission end, and the transmission end is a terminal device or a transmission and reception point (TRP).
