Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing power consumption for position estimation procedures in user equipment (UE) due to limitations in determining optimal power usage parameters for positioning frequency layers, PRS resource processing, and measurement types, which affects performance and battery life.

Innovation Solution

A method and system for determining power consumption in UE for position estimation procedures based on specific power consumption parameters such as layer-specific parameters, positioning frequency layer processing capability, PRS resource processing capability, and PRS measurement type capability, allowing for optimized power management and reduced consumption during positioning measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If position estimation procedures are performed with high processing capability, then positioning accuracy and performance are improved, but power consumption increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power consumption modeling that adapts to varying positioning requirements. The system adjusts power consumption parameters based on actual positioning needs, processing capability, and measurement type, allowing the UE to operate at optimal power levels rather than fixed high-power modes. This resolves the contradiction by making power consumption dynamic rather than static, matching energy usage to actual positioning accuracy requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a comprehensive set of power consumption parameters including layer-specific parameters, positioning frequency layer processing capability, PRS resource processing capability, and PRS measurement type capability. By modeling and optimizing these parameters, the system can adjust positioning processing characteristics to achieve required accuracy while minimizing power consumption, directly addressing the trade-off between positioning precision and energy usage.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple positioning frequency layers are processed concurrently, then positioning performance is improved, but power consumption increases

Engineering Contradiction:
Improvepositioning processing capabilityVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by processing only the necessary number of positioning frequency layers concurrently based on actual positioning requirements and power constraints. Rather than always processing maximum layers, the system adjusts the degree of parallel processing to match needs, reducing unnecessary power consumption while maintaining adequate positioning performance. This resolves the contradiction by avoiding excessive parallel processing when full capability is not required.

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If advanced PRS measurement types are used, then positioning accuracy is improved, but power consumption increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidmeasurement processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements local quality by selecting and applying specific PRS measurement types based on local conditions including positioning requirements, channel characteristics, and power constraints. Rather than uniformly applying the most advanced measurement types everywhere, the system adapts measurement complexity to local needs, using advanced types only when they provide necessary accuracy improvements. This resolves the contradiction by making measurement complexity location and situation-dependent rather than uniformly high.

Inventive Principle:
Principle #3Local quality
