5G Location Resource Coordination for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G location networks, there is no dynamic coordination mechanism for location resources, leading to additional signal interference and wastage of wireless resources due to redundant location resources.
Innovation Solution
A method for coordinating location resources by sending coordination information to a base station before location measurement, including identity information of a target cell and dedicated location resource information, to activate or update resources efficiently, reducing interference and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant location resources are deployed in 5G networks, then location service coverage and reliability are improved, but signal interference to other network units increases and wireless resources are wasted
Solution Approach 1:
The patent implements dynamic coordination of location resources by establishing a coordination mechanism between network nodes. The system dynamically activates, deactivates, or modifies location resources based on real-time location service requirements, transforming static resource deployment into dynamic resource allocation that adapts to changing network conditions and service demands.
Solution Approach 2:
The patent changes the operational parameters of location resources through coordinated control. Network nodes exchange coordination information that modifies resource parameters such as activation status, time windows, and configuration settings, allowing the same physical resources to be optimally allocated across different services and time periods without causing interference.
2Productivity
If location resources are activated without dynamic coordination, then location measurement can be performed, but wireless resources are wasted due to redundancy
Solution Approach 1:
The patent establishes a feedback loop where network nodes exchange coordination information about location resource usage. The system receives feedback on resource activation status and service requirements, then adjusts resource allocation accordingly, ensuring that location resources are activated only when and where needed for specific measurement tasks, thereby avoiding unnecessary resource waste.
Solution Approach 2:
The patent implements preliminary coordination before activating location resources. Network nodes exchange information about intended location measurements and required resources in advance, allowing the system to pre-configure and activate only the necessary resources for upcoming measurements, rather than maintaining redundant resources in a standby state.
3Measurement precision
If dedicated location resource information is configured for each target cell, then location measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal coordination framework that can be applied across different network nodes and cells. The same coordination mechanism and information exchange protocol serve multiple purposes: resource activation, deactivation, modification, and allocation across different target cells, reducing the need for cell-specific complex configurations while maintaining measurement precision.
Data Source
AI summary
A location resource coordinating method, a location resource coordinating device, a network node, a UE, and a base station are provided. The location resource coordinating method includes: sending location resource coordination information to a base station before performing location measurement for a serving UE; the location resource coordination information includes identity information of a target cell of the base station, and carries dedicated location resource information configured for the target cell, or the location resource coordination information includes the identity information of a target cell for which the base station activates a location resource, and instructs the base station to activate pre-configured dedicated location resource information; the base station is a base station related to the serving UE.
