Sidelink Positioning Error Messaging With Typed Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in error messaging for sidelink positioning, where error messages do not adequately indicate the type of error, leading to incorrect correction attempts and high signaling overhead, which can result in failure of sidelink positioning operations.
Innovation Solution
Implementing a format for error messages in sidelink positioning that includes parameters to specifically indicate the type of error, such as measurement, location, or assistance data information errors, allowing devices to transmit corrected messages effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If error messages do not include specific error type parameters, then the message format remains simple, but devices cannot accurately identify error types leading to incorrect correction attempts
Solution Approach 1:
The error message is segmented into distinct parameters where each parameter corresponds to a specific error type (measurement error, location error, assistance data error). This segmentation allows devices to identify and correct specific error types without needing to parse complex message structures, thus improving measurement precision while keeping the overall format manageable through systematic organization.
Solution Approach 2:
The patent introduces specific parameters to the error message format that indicate the type of error encountered. By changing the message format to include these identifying parameters, the system enables accurate error type identification without requiring fundamental structural complexity, as the parameters are integrated into the existing message framework.
2Reliability
If devices transmit detailed error information, then error correction accuracy improves, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential error type information from potentially detailed error reports and transmits only these critical parameters in the error message. This extraction approach ensures that devices receive sufficient information for accurate correction while minimizing unnecessary data transmission, thus improving reliability without excessive signaling overhead.
Solution Approach 2:
The system implements partial action by transmitting only the necessary error type parameters rather than all possible error details. This partial transmission provides sufficient information for correction while avoiding excessive signaling overhead that would result from transmitting complete error reports with all possible metadata and context information.
3Reliability
If error messages lack specific error type indicators, then message structure remains simple, but correction attempts become incorrect and positioning operations fail
Solution Approach 1:
The error message parameters are designed to serve multiple functions: they identify error types, enable selective correction, and maintain compatibility with existing positioning protocols. This multi-functionality approach improves positioning operation success rates without requiring entirely new message structures, as the parameters integrate with the existing SLPP message framework.

AI summary
Various aspects of the present disclosure relate to error messaging for sidelink positioning. A first device, such as a UE or a location management function (LMF), receives, from a second device, a first sidelink positioning protocol (SLPP) message comprising information associated with sidelink positioning. The first device determines sidelink positioning error information based on an error in the information associated with the sidelink positioning. The first device transmits a second SLPP message comprising at least one parameter that indicates the sidelink positioning error information. The second device transmits, to the first device, a third SLPP message based on the sidelink positioning error information.
