Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately identifying and reporting positioning errors during positioning sessions, which can hinder precise location determination in 5G networks.
Innovation Solution
A method and apparatus for a network entity to engage in positioning sessions, determine positioning errors, and report these errors to a second network entity using a bitmap or based on priority assignments, facilitating improved error identification and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple positioning error causes are reported simultaneously, then positioning accuracy improves, but reporting complexity increases
Solution Approach 1:
The patent segments multiple positioning error causes into individual bitmap indicators, where each bit position represents a specific error cause. This allows the system to report multiple errors simultaneously while maintaining a compact, standardized format that reduces reporting complexity despite the multiplicity of errors being reported.
Solution Approach 2:
The patent transitions from reporting error causes in a linear or hierarchical manner to using a bitmap representation where error causes are encoded in a parallel, multi-dimensional space. Each bit in the bitmap represents a different error cause, enabling simultaneous reporting of multiple errors without increasing sequential processing complexity.
2Measurement precision
If all positioning error causes are reported, then error identification accuracy improves, but information processing overhead increases
Solution Approach 1:
The patent uses a bitmap as a compact copy or representation of multiple error causes. Instead of transmitting detailed information about each error cause separately, the system creates a compressed bitmap copy where each bit represents an error cause, significantly reducing information processing overhead while maintaining complete error identification capability.
3Reliability
If positioning error reporting is enhanced with detailed error causes, then positioning reliability improves, but communication protocol complexity increases
Solution Approach 1:
The patent creates a universal bitmap format that can represent multiple different error causes using the same standardized structure. This multi-functional approach allows the communication protocol to handle various error types without requiring separate reporting mechanisms for each error cause, thereby reducing protocol complexity while enhancing positioning reliability through comprehensive error reporting.

AI summary
In an aspect, a first network entity may engage in a positioning session with a second network entity. The first network entity may determine that a plurality of positioning errors associated with a corresponding plurality of positioning error causes occurred during the positioning session. The first network entity may report a positioning error cause of a positioning error of the plurality of positioning errors to the second network entity during the positioning session based on priorities assigned to the plurality of positioning error causes.
