Batch Positioning Reporting for 5G PRS Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication systems face challenges in efficiently reporting positioning reference signal (PRS) measurements across multiple instances, leading to inconsistencies and increased latency, which affects positioning accuracy and energy consumption.
Innovation Solution
A method for batch reporting of PRS measurements, where a telecommunication device establishes a positioning session with a network entity and transmits a capability report indicating its measurement reporting capacity, including the quantity of measurement sub-reports and elements per PRS instance, ensuring consistent PRS level measurements and processing priority, while also requesting reporting consistency parameters from a server to optimize measurement reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If batch measurement reporting is implemented for multiple PRS instances, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the measurement reporting process by dividing PRS instances into different batches based on device capability. The capability report structure separates measurement elements into groups, allowing the network to selectively request measurements from specific batches. This segmentation enables positioning accuracy improvement through multi-instance reporting while managing device complexity by allowing selective processing of different instance batches.
Solution Approach 2:
The patent implements dynamic measurement reporting where the device adapts its reporting behavior based on capability assessments. The capability report dynamically indicates the maximum number of PRS instances the device can handle, and the network dynamically adjusts measurement requests based on this capability. This dynamic approach allows the system to optimize positioning accuracy while preventing overwhelming the device with excessive measurement tasks.
2Measurement precision
If measurements of multiple PRS instances are reported in batch, then positioning accuracy is improved, but latency increases
Solution Approach 1:
The patent employs periodic measurement reporting where PRS instances are measured and reported in structured batches at defined intervals. The capability report specifies the device's capacity to handle periodic measurement cycles across multiple instances. This periodic approach allows the system to accumulate measurements from multiple instances for improved positioning accuracy while maintaining predictable latency through regular reporting cycles rather than continuous or ad-hoc reporting.
3Measurement precision
If batch measurement reporting is implemented, then positioning accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent changes key parameters of the measurement reporting process based on device capability. The capability report communicates parameters such as the maximum number of PRS instances the device can measure and report, the supported measurement batches, and the processing priority levels. By adjusting these parameters according to device capability, the system achieves improved positioning accuracy through multi-instance reporting while preventing excessive energy consumption by limiting measurements to what the device can efficiently handle.
4Stability of the object's composition
If capability reporting for batch measurement is implemented, then measurement consistency is improved, but signaling overhead increases
Solution Approach 1:
The patent implements a universal capability report structure that serves multiple functions simultaneously. The capability report not only indicates the device's maximum measurement capacity but also establishes the framework for consistent measurement reporting across multiple PRS instances. This multi-functional approach improves measurement consistency by providing a standardized reporting structure while minimizing signaling overhead by consolidating capability information into a single comprehensive report rather than requiring separate signaling for each measurement parameter.
