Reference Signal Handover Configuration for Moving Terminals

Solution Overview

Problem

Existing positioning technologies face challenges in configuring reference signals for terminal devices that move between RRC inactive or idle states, leading to improper signal transmissions and resource wastage.

Innovation Solution

A communication method where a first network apparatus sends second information to a second network apparatus to adjust the number of reference signal transmissions based on the terminal device's past situation, reducing improper transmissions and resource waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the first network apparatus sends first information to configure reference signal transmissions for a terminal device, then the terminal device can maintain positioning functionality, but when the terminal device moves to a different network apparatus (second network apparatus), the reference signal transmission configuration becomes improper and causes resource wastage

Engineering Contradiction:

Improvepositioning functionalityVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The first network apparatus calculates and determines the number of reference signal transmissions in advance based on the terminal device's past situation before the terminal device moves. This preliminary calculation ensures that the terminal device has an appropriate transmission configuration when it moves to the second network apparatus, preventing resource wastage while maintaining positioning functionality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first network apparatus sends second information (which includes the calculated number of reference signal transmissions) to the second network apparatus in response to a terminal device context request. This feedback mechanism ensures that the second network apparatus receives updated configuration information that reflects the terminal device's actual positioning needs, avoiding improper transmissions.

Inventive Principle:

Principle #23Feedback

2Stability of the object's composition

If the second network apparatus configures reference signal transmissions based on first information from the first network apparatus, then the terminal device maintains continuity of service, but the transmission configuration does not match the terminal device's current situation causing improper transmissions

Engineering Contradiction:

Improveservice continuityVSAvoidconfiguration accuracy

Core Design Contradiction:

Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The first network apparatus acts as an intermediary that calculates the appropriate number of reference signal transmissions based on the terminal device's past situation and communicates this information to the second network apparatus. This intermediary calculation ensures that the second network apparatus receives accurate configuration information that matches the terminal device's current positioning needs, rather than using outdated first information directly.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the terminal device continues using reference signal transmission configuration from the first network apparatus after moving, then network switching is simplified, but resource wastage increases due to improper transmissions

Engineering Contradiction:

Improvenetwork switchingVSAvoidresource wastage

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The first network apparatus calculates and determines the number of reference signal transmissions in advance based on the terminal device's past situation before the terminal device moves. This preliminary calculation ensures that the terminal device has an appropriate transmission configuration when it moves to the second network apparatus, preventing resource wastage while maintaining positioning functionality.
