Solution Overview

Problem

The issue of resource waste and capacity impact in 5G wireless communication networks due to unreleased positioning reference signal resources, leading to inefficient utilization of cell capacity.

Innovation Solution

A communication method where a first network device sends a message to a first access network device to release a positioning reference signal resource, allowing the access network device to free up resources and avoid capacity impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the positioning reference signal resource is always occupied (not released), then the terminal device can maintain positioning functionality, but the cell capacity is affected and resources are wasted

Engineering Contradiction:
Improvepositioning functionalityVSAvoidcell capacity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic resource management by introducing a release mechanism for positioning reference signal resources. The access network device receives indication information to release the positioning reference signal resource when the terminal device is released, re-applies for, or updates the resource. This transforms the static resource occupation into a dynamic state where resources are allocated and released based on actual positioning needs, thereby resolving the contradiction between maintaining positioning reliability and improving cell capacity.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the positioning reference signal resource is always occupied, then positioning accuracy is maintained, but resource utilization is reduced

Engineering Contradiction:
Improvepositioning accuracyVSAvoidresource utilization
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent applies the discarding and recovering principle by releasing positioning reference signal resources when they are no longer needed. The access network device receives indication information to release the resource when the terminal device releases, re-applies for, or updates the positioning reference signal resource. This allows the system to discard occupied resources and recover them for other uses, improving overall resource utilization while maintaining positioning accuracy when needed.

Inventive Principle:
Principle #34Discarding and recovering

3Duration of action of stationary object

If the positioning reference signal resource is always occupied, then the terminal device can continuously perform positioning, but interference increases and resource efficiency decreases

Engineering Contradiction:
Improvecontinuous positioningVSAvoidinterference
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent implements periodic resource allocation through a release mechanism. Instead of continuous occupation, the positioning reference signal resource is allocated periodically based on terminal device needs. The access network device receives indication information to release the resource at appropriate intervals when the terminal device releases, re-applies for, or updates the resource. This periodic action reduces continuous interference while maintaining positioning capability when required.

Inventive Principle:
Principle #19Periodic action
