Configured Time Window Error Reporting for Wireless Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately reporting errors when positioning measurements for a user equipment (UE) are not obtained within a configured time window, leading to uncertainties and complications in location determination.
Innovation Solution
Implementing a method where an entity in the wireless network receives a configured time window to obtain positioning measurements for a UE, attempts to obtain these measurements, and sends an error message to a positioning entity if they fail to do so within the specified time frame, indicating the timing and cause of the error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If positioning measurements are obtained within a configured time window, then latency is reduced and location determination speed is improved, but uncertainties and complications in error reporting increase
Solution Approach 1:
The error reporting mechanism is segmented into distinct components: error detection flags, error type identification, and optional error details. This segmentation allows for systematic and accurate error reporting within the constrained time window, resolving the contradiction between speed and reliability.
Solution Approach 2:
The patent implements a feedback mechanism where the measuring entity reports errors back to the positioning entity through structured error messages. This feedback loop enables the positioning entity to understand measurement failures and adjust future positioning requests, improving overall system reliability while maintaining tight time windows.
2Measurement precision
If a configured time window is used for positioning measurements, then location determination precision is improved, but device complexity increases due to additional error handling requirements
Solution Approach 1:
Error handling is extracted as a separate, standardized function from the main positioning measurement process. The patent defines specific error types and reporting formats that can be independently implemented, reducing the perceived complexity by isolating error management from core positioning logic.
Solution Approach 2:
The patent introduces parameterized error reporting where error messages include specific parameters such as error type identifiers, timing information, and optional details. This parameterization provides a flexible framework that maintains precision while managing complexity through standardized data structures.
3Reliability
If error reporting is implemented within the configured time window, then control over uncertainties is improved, but the processing load and system complexity increase
Solution Approach 1:
The error reporting mechanism allows for partial reporting where only essential error information is included in the immediate error message, while detailed analysis can be performed separately. This partial action approach provides control over uncertainties without requiring complete processing within the tight time window, thus managing processing load.

AI summary
Positioning measurements to determine the location of a user equipment (UE) may be obtained within a configured time window, such as a measurement time window or positioning reference signal (PRS) processing window. If one or more position measurements cannot be obtained within the configured window, the measuring entity may provide an error report to the positioning entity indicating that it was unable to obtain one or more positioning measurements within the configured time window. The error message may be provided in the provide location information report. The error message may include the timing of the error within the configured time window, e.g., whether the error occurred at the beginning or end of the configured time window. The error message may further indicate the cause of the error, such as failure to receive a PRS processing window, or that the PRS had low priority relative to downlink signals or channels.
