Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The coordination of positioning measurement and paging detection in terminal devices in RRC idle or inactive states is inefficient, leading to increased power consumption and communication delays due to frequent state transitions and synchronization requirements.

Innovation Solution

A method is provided to associate time periods for positioning measurement or SRS transmission with paging detection, ensuring they are either partially or fully overlapping or adjacent, with a defined threshold to minimize synchronization losses, and a mechanism to handle conflicts between positioning measurement and PEI detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the terminal device performs positioning measurement and paging detection separately with frequent state transitions, then the positioning measurement can be performed, but the power consumption increases and communication delays occur

Engineering Contradiction:

Improvepositioning measurementVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent combines positioning measurement and paging detection into a unified time period, allowing the terminal device to perform both functions simultaneously without frequent state transitions. The positioning measurement time period is set to overlap with or be adjacent to the paging detection time period, enabling the terminal to maintain a single operational state while completing both tasks, thereby reducing power consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The network side device determines the first time period for positioning measurement in advance, considering the terminal device's paging detection schedule. By pre-configuring the timing relationship between positioning measurement and paging detection, the terminal device can prepare for both operations simultaneously, avoiding last-minute state transitions and reducing energy consumption.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

Engineering Contradiction:

Improvepositioning measurementVSAvoidcommunication delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges positioning measurement and paging detection into a coordinated time schedule where the first time period for positioning measurement overlaps with or is adjacent to the second time period for paging detection. This eliminates the need for the terminal device to transition between different operational states repeatedly, thereby reducing communication delays and improving overall efficiency.

Inventive Principle:

Principle #5Merging (Combining)

3Use of energy by moving object

If the first time period for positioning measurement is set to overlap with the second time period for paging detection, then power consumption is reduced, but timing coordination complexity increases

Engineering Contradiction:

Improvepower consumptionVSAvoidtiming coordination

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The network side device receives information about the terminal device's paging detection schedule and uses this feedback to determine the first time period for positioning measurement. This feedback mechanism ensures that the timing coordination is automatically adjusted based on actual network conditions, simplifying the complexity through centralized control rather than requiring complex distributed coordination between terminal and network.

Inventive Principle:

Principle #23Feedback

4Use of energy by moving object

If the terminal device performs positioning measurement during DRX cycle, then power consumption is reduced, but positioning measurement accuracy may be affected

Engineering Contradiction:

Improvepower consumptionVSAvoidpositioning measurement accuracy

Core Design Contradiction:

Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The patent applies local quality by configuring the first time period for positioning measurement to specifically overlap with or be adjacent to the paging detection time period within the DRX cycle. This localized timing ensures that positioning measurement occurs during a specific window when the terminal device is already in an active state for paging detection, maintaining measurement accuracy while still utilizing the DRX mechanism for power saving.

Inventive Principle:

Principle #3Local quality
