Solution Overview

Problem

Existing communication systems face challenges in implementing low-latency positioning due to the limitations of measurement gaps, which require terminals to interrupt data transmission for PRS measurements, leading to excessive positioning delays.

Innovation Solution

The method allows terminals to perform measurements on multiple positioning reference signals within a first positioning measurement window without interrupting data transmission, enabling low-latency positioning by configuring a first positioning measurement window based on various parameters such as time and frequency domain information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If terminals perform measurement on positioning reference signals within a measurement gap, then positioning measurement can be conducted, but positioning delay increases and data transmission is interrupted

Engineering Contradiction:

Improvepositioning measurementVSAvoidpositioning delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The network device pre-configures a positioning measurement window that includes the positioning reference signal, allowing the terminal to perform measurements without waiting for a measurement gap. This preliminary configuration enables the terminal to immediately measure the positioning reference signal when the window occurs, reducing positioning delay while maintaining measurement accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a dynamic positioning measurement window configuration that can be independently set from traditional measurement gaps. The window's time domain parameters (start position, length) are dynamically adjustable based on positioning requirements, allowing flexible optimization between measurement precision and positioning speed without being constrained by fixed measurement gap periodicity

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If terminals interrupt data transmission for PRS measurement, then measurement can be performed, but positioning delay increases

Engineering Contradiction:

ImprovePRS measurementVSAvoiddata transmission continuity

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the positioning measurement process from the traditional measurement gap framework. By creating an independent positioning measurement window with its own time domain configuration, the measurement function is separated from data transmission constraints, allowing measurements to occur without interrupting ongoing data transmissions and maintaining both measurement precision and transmission continuity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning measurement window is designed to serve multiple purposes: it enables PRS measurement while allowing data transmission to continue in parallel. This multi-functional approach eliminates the need to choose between measurement and transmission, as both can occur simultaneously within the configured window structure

Inventive Principle:

Principle #6Universality (Multi-functionality)
