Solution Overview

Problem

Current 3GPP positioning measurement methods do not effectively determine optimal positioning measurements from multiple receiver units in 5G NR systems, leading to inaccuracies due to factors like multipath propagation.

Innovation Solution

A method and device that measure and determine optimal positioning measurements by receiver units in a receiver unit array, using modes such as maximum, minimum, average, or weighted average calculations based on parameters like SNR, SINR, and received power, to minimize the influence of multipath propagation and improve measurement precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple receiver units independently measure reference signals to improve positioning reliability, then measurement precision improves, but determining the optimal measurement becomes complex

Engineering Contradiction:
Improvepositioning measurement precisionVSAvoidmeasurement determination complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-defining multiple determination modes (maximum, minimum, average, weighted average) for selecting optimal positioning measurements. These modes are established in advance to systematically handle the complexity of processing measurements from multiple receiver units, enabling automated selection without real-time complex decision-making.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by introducing different determination modes that transform the raw measurements into optimal positioning measurements through various mathematical operations (maximum, minimum, average, weighted average). This allows flexible adjustment of the determination process based on different scenarios and requirements.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If all receiver units provide measurements to ensure comprehensive data, then positioning reliability improves, but processing time increases

Engineering Contradiction:
Improvepositioning reliabilityVSAvoidmeasurement processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies the taking out principle by extracting only the necessary information from multiple receiver unit measurements to determine the optimal positioning measurement. Instead of processing all measurements equally, it selectively extracts the most relevant data through predefined modes (e.g., selecting maximum, minimum, or average values), thereby reducing processing time while maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If receiver units process measurements independently to improve processing efficiency, then productivity improves, but measurement accuracy deteriorates due to multipath propagation

Engineering Contradiction:
Improvemeasurement processing efficiencyVSAvoidpositioning measurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent applies merging by combining measurements from multiple receiver units through predefined determination modes (maximum, minimum, average, weighted average). This consolidation approach leverages the collective data from all receiver units to counteract the effects of multipath propagation and improve overall measurement accuracy while maintaining processing efficiency through automated mode-based selection.

Inventive Principle:
Principle #5Merging (Combining)
