Find Innovative SolutionsGenerate Solutions
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 resource utilization and interference.
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 identify and release the resource, thereby avoiding resource occupation and improving cell capacity.
Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The patent implements dynamic resource management by introducing a release mechanism that allows positioning reference signal resources to be released when no longer needed. The network device receives indication information about terminal device status (releasing, re-applying, or updating positioning resources) and accordingly releases the positioning reference signal resource on the positioning reference signal resource pool, making the resource occupation state changeable rather than static.
Solution Approach 2:
The patent changes the state parameter of the positioning reference signal resource from a fixed occupied state to a variable state that can transition between occupied and released. By introducing a release mechanism triggered by terminal device status changes, the resource allocation parameter is dynamically adjusted to match actual positioning needs, resolving the contradiction between maintaining positioning reliability and improving cell capacity.
2Measurement precision
If the positioning reference signal resource is always occupied, then positioning accuracy is maintained, but resource utilization deteriorates
Solution Approach 1:
The patent implements a resource recovery mechanism where positioning reference signal resources are released back to the pool when terminal devices release, re-apply, or update their positioning resources. This allows previously occupied resources to be discarded from current allocation and made available for recovery and reuse by other terminal devices, improving overall resource utilization while maintaining positioning accuracy for active devices.
Solution Approach 2:
The patent introduces dynamic resource allocation where the positioning reference signal resource occupation state is no longer fixed but changes based on terminal device positioning status. The network device dynamically releases resources based on received indication information, creating a flexible system that adapts resource allocation to actual positioning needs, thereby improving resource utilization without compromising positioning accuracy.
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 network performance deteriorates
Solution Approach 1:
The patent implements periodic resource allocation where positioning reference signal resources are allocated to terminal devices only when needed for positioning operations. Instead of continuous occupation, resources are released when terminal devices release, re-apply, or update their positioning resources, creating a periodic on-demand allocation pattern that reduces continuous interference while maintaining positioning capability when required.
Solution Approach 2:
The patent extracts the positioning reference signal resource from permanent occupation and makes it available for release under specific conditions. By taking out the resource from the always-occupied state and introducing a release mechanism triggered by terminal device status changes, the system reduces harmful interference generated by continuous resource occupation while maintaining the ability to provide continuous positioning when actually needed.
