Sidelink Positioning Range Filtering for 5G UE

Solution Overview

Problem

Current wireless communication systems, particularly in the context of 5G, face challenges in efficiently managing positioning requests and responses between user equipment (UEs) within specific range zones, which affects sidelink positioning accuracy and communication efficiency.

Innovation Solution

The method involves a UE receiving a positioning request with a zone identifier and determining whether to transmit a positioning response based on being within a minimum positioning range (Min-PR) and maximum positioning range (Max-PR) of the target UE, allowing for precise sidelink positioning sessions and zone identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If UEs transmit positioning responses to all positioning requests, then positioning availability is improved, but communication overhead and resource consumption increase

Engineering Contradiction:

Improvepositioning availabilityVSAvoidcommunication overhead

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by differentiating the response behavior based on the assisting UE's location relative to the target UE. UEs within the minimum positioning range (Min-PR) transmit positioning responses, while UEs outside this range do not, creating location-dependent quality in the positioning service delivery.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements preliminary action by having the assisting UE determine its distance to the target UE before responding to positioning requests. This pre-check of the minimum positioning range condition allows the system to avoid unnecessary responses from UEs that are too far away, reducing communication overhead while maintaining positioning availability for relevant UEs.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If UEs outside minimum positioning range transmit positioning responses, then positioning coverage is improved, but positioning accuracy deteriorates

Engineering Contradiction:

Improvepositioning coverageVSAvoidpositioning accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies local quality by differentiating the response behavior based on the assisting UE's location relative to the target UE. UEs within the minimum positioning range (Min-PR) transmit positioning responses, while UEs outside this range do not, creating location-dependent quality in the positioning service delivery.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses the minimum positioning range (Min-PR) as an intermediary filter between the positioning request and response. This intermediary mechanism selectively allows or blocks responses based on the assisting UE's distance to the target UE, ensuring that only UEs close enough to provide accurate positioning information respond to requests.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Speed

If UEs continuously monitor positioning requests, then positioning responsiveness is improved, but energy consumption increases

Engineering Contradiction:

Improvepositioning responsivenessVSAvoidenergy consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by having the assisting UE determine its distance to the target UE before responding to positioning requests. This pre-check of the minimum positioning range condition allows the system to avoid unnecessary responses from UEs that are too far away, reducing communication overhead while maintaining positioning availability for relevant UEs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies self-service by having each assisting UE autonomously determine whether it should respond to positioning requests based on its own location relative to the target UE. This self-evaluation mechanism eliminates the need for continuous monitoring and responding to all requests, reducing energy consumption while maintaining responsiveness for relevant positioning requests.

Inventive Principle:

Principle #25Self-service

AI summary

Disclosed are techniques for wireless communication. In an aspect, an assisting user equipment (UE) receives a positioning request from a target UE, the positioning request including a zone identifier (ID) identifying a zone in which the target UE is located, based on the assisting UE being outside a minimum positioning range (Min-PR) and within a maximum positioning range (Max-PR) of the target UE, determines whether to transmit a positioning response to the target UE, and based on the assisting UE being within the Min-PR of the target UE, transmits the positioning response to the target UE.
