Idle-State UE Signal Reception Based on Coverage Signal Quality

Solution Overview

Problem

Non-BL UEs in enhanced coverage mode experience increased power consumption and reduced user experience due to unnecessary reading of system information in both regular and enhanced coverage modes, leading to inefficient network resource usage and mobility issues.

Innovation Solution

A signal reception method for UEs in idle-state that monitors signal quality and receives system information on demand based on the signal quality, allowing UEs to transition between coverage modes as needed, reducing unnecessary power consumption and optimizing system information retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If UEs in enhanced coverage mode read system information in both regular and enhanced coverage modes, then coverage reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecoverage reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic adaptation by enabling UEs to flexibly switch between reading system information in enhanced coverage mode and regular coverage mode based on real-time signal quality measurements. The UE dynamically determines which reading mode to use, transitioning from a static always-read-both approach to a dynamic conditional approach that adapts to current radio conditions, thereby reducing unnecessary power consumption while maintaining coverage reliability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of system information reading by introducing signal quality as a decision criterion. When signal quality exceeds a threshold, the UE changes its behavior to read only regular coverage mode system information; when signal quality is below the threshold, it reads enhanced coverage mode system information. This parameter-based adaptation resolves the contradiction by adjusting reading behavior based on actual network conditions.
