Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in the context of 5G, face challenges in accurately positioning user equipment (UEs) due to limitations in reference signal processing and measurement techniques, which affect the precision and efficiency of location estimation.
Innovation Solution
The implementation of a method that involves a wireless node receiving a configuration for a virtual instance of reference signal for positioning (RS-P) resources, performing measurements, and transmitting measurement reports to a position estimation entity, allowing for enhanced positioning accuracy through separate RS-P resource sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional reference signal processing is used for positioning, then the system complexity remains low, but the positioning accuracy is insufficient
Solution Approach 1:
The reference signal resources are segmented into multiple virtual instances (first virtual instance, second virtual instance, etc.), each associated with separate physical RS-P resources. This segmentation allows the wireless node to perform measurements on different virtual instances using separate physical resources, thereby improving positioning accuracy through diversified measurement opportunities while managing system complexity through structured resource organization.
2Measurement precision
If multiple virtual instances of RS-P resources are implemented, then the positioning accuracy improves, but the configuration and management complexity increases
Solution Approach 1:
The position estimation entity serves as an intermediary that receives measurement reports from the wireless node and processes the measurement information related to multiple virtual instances. This intermediary approach simplifies the overall system operation by centralizing the complex processing and calculation tasks for positioning, allowing the wireless node to focus on measurement while the position estimation entity handles the complexity of multi-instance data processing.
3Measurement precision
If separate RS-P resource sets are used for different virtual instances, then the measurement precision improves, but the resource allocation complexity increases
Solution Approach 1:
The patent introduces a virtual instance dimension to organize RS-P resources. Instead of managing resources solely in the physical domain, the system creates virtual instances (first virtual instance, second virtual instance) that map to separate physical resource sets. This dimensional approach allows multiple virtual instances to share the same physical resources in a structured manner, improving measurement precision through virtualization while simplifying resource allocation through the virtual-to-physical mapping framework.

Disclosed are techniques for communication. In an aspect, a wireless node receives a configuration associated with one or more reference signal for positioning (RS-P) resources from a position estimation entity. The wireless node performs measurement(s) of a set of RS-P resources, and derives measurement information associated with a first virtual instance of the one or more RS-P resources based on the measurement(s). The wireless node transmits a measurement report comprising the measurement information to the position estimation entity.
