Solution Overview

Problem

There is a need for improved validation and management of positioning models in wireless communication systems, particularly in 5G NR, to ensure model validity and reduce latency while accounting for UE hardware limitations.

Innovation Solution

A method and apparatus for a user equipment (UE) to receive a configuration to validate a positioning model, measure positioning signals, calculate model outputs, and transmit a validation report, while a network entity can transmit configurations for model activation, deactivation, and switching, using LTE positioning protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If positioning models are validated before activation, then model validity and positioning accuracy are improved, but validation time and processing latency increase

Engineering Contradiction:

Improvepositioning model validityVSAvoidvalidation latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs positioning model validation in advance before activation, using validation configurations received from the network entity. The UE validates the positioning model by obtaining validation data, processing it through the positioning model, and comparing results against expected outcomes. This preliminary validation ensures model reliability is established before deployment, preventing invalid models from being activated while maintaining acceptable latency through efficient validation procedures.

2Reliability

If multiple positioning models are managed and validated, then positioning accuracy and adaptability are improved, but device complexity and processing requirements increase

Engineering Contradiction:

Improvepositioning accuracyVSAvoidmodel management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments positioning model management into distinct functional components: validation configuration reception, validation data acquisition, model processing, result comparison, and activation control. Each positioning model is validated independently through separate validation configurations, allowing the UE to manage multiple models without overwhelming complexity. The network entity provides individual validation configurations for each model, enabling systematic management of multiple positioning models with different validation requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network entity acts as an intermediary that provides validation configurations and expected validation data to the UE. This intermediary role simplifies device complexity by centralizing the management of validation parameters and criteria. The UE receives structured validation configurations from the network entity, which define the validation process parameters, reducing the burden on the UE to independently manage complex validation logic for multiple positioning models.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If positioning model validation is performed with detailed configurations, then validation precision and model reliability are improved, but processing time and energy consumption increase

Engineering Contradiction:

Improvevalidation precisionVSAvoidprocessing energy

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The validation configuration includes adjustable parameters that define the validation process characteristics, such as validation data selection criteria, processing thresholds, and comparison tolerances. By optimizing these parameters, the system achieves high validation precision while controlling processing energy consumption. The network entity provides validation configurations with parameter settings that balance precision requirements against energy constraints, allowing the UE to perform detailed validation when necessary while reducing processing intensity when energy is constrained.

AI summary

A network entity, for example a location management function (LMF), may transmit a first configuration to validate a positioning model. A user equipment (UE) may receive the first configuration to validate the positioning model. The UE may receive a set of positioning signals. The UE may measure the set of positioning signals based on the first configuration. The UE may obtain a set of positioning model outputs based on the measured set of positioning signals and the first configuration. The UE may transmit a validation report based on the set of positioning model outputs and the first configuration. The network entity may receive the validation report. The validation report may include at least one of a first indicator that the positioning model is valid or a second indicator of a set of positioning model outputs based on the first configuration.
