Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing positioning technologies face challenges in efficiently managing bandwidth part (BWP) switching and measurement gap (MG) configurations, leading to increased latency, complexity, and power consumption, particularly for low accuracy and low latency use cases.

Innovation Solution

A device performs positioning measurements of a first set of reference signals within a specific frequency range and transmits a measurement report only when quality of service (QoS) requirements are satisfied, without requiring BWP switching or MG configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If BWP switching and measurement gap configurations are implemented for positioning measurements, then positioning accuracy is improved, but latency and device complexity increase

Engineering Contradiction:

Improvepositioning accuracyVSAvoidlatency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments positioning measurements into two categories: those that require BWP switching/MG configurations and those that do not. The terminal device performs measurements on reference signals that can be measured without BWP switching first, and only initiates BWP switching for measurements that require it. This segmentation reduces overall latency by avoiding unnecessary BWP switching operations while still achieving required positioning accuracy.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If BWP switching and measurement gap configurations are implemented for positioning measurements, then positioning accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidcomplexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the positioning measurement process into simplified stages: (1) check if reference signals can be measured in current BWP, (2) perform measurements without BWP switching if possible, (3) only switch BWP if absolutely necessary for accuracy. This segmented approach reduces device complexity by avoiding the need to manage complex BWP switching sequences and measurement gap configurations for all positioning measurements.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If BWP switching is performed for positioning measurements, then measurement coverage is improved, but power consumption increases

Engineering Contradiction:

Improvemeasurement coverageVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by performing BWP switching only for the minimum necessary subset of positioning measurements that cannot be completed in the current BWP. Instead of switching BWP for all positioning reference signals, the terminal device identifies and switches only for those specific signals required to meet positioning accuracy requirements, thereby reducing overall power consumption while maintaining adequate measurement coverage.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Embodiments of the present disclosure relate to positioning. A first device performs positioning measurements of a first set of reference signals in a first frequency range. If the first device determines that quality of service requirements for positioning the first device are satisfied, the first device transmits a first measurement report to a second device. The first measurement report only comprises a first set of measurement results associated with the first set of reference signals.
