Solution Overview

Problem

User equipment (UE) lacks flexibility in entering and exiting reduced power states, leading to potential increased power consumption.

Innovation Solution

A method and apparatus for wireless communication that allows a UE to request and be granted a specific operation state, either a reduced power state or a non-reduced power state, with a network entity accepting or rejecting the request and transmitting an appropriate instruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network entity controls UE power state transitions, then network coordination is improved, but UE flexibility and power management capability deteriorate

Engineering Contradiction:

Improvenetwork coordinationVSAvoidUE flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic power state management where the UE can transition between reduced power state and non-reduced power state based on its energy status. The UE dynamically selects operation states and sends requests to the network entity, allowing flexible adaptation while maintaining network coordination through standardized signaling procedures.

Inventive Principle:

Principle #15Dynamics

2Use of energy by moving object

If the UE frequently transitions to reduced power state, then power consumption is reduced, but communication responsiveness and service quality deteriorate

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication responsiveness

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The UE dynamically adjusts its power state based on energy status thresholds. When energy status indicates sufficient power, the UE operates in non-reduced power state for optimal communication performance. When energy status drops below thresholds, the UE transitions to reduced power state to conserve energy, creating a dynamic balance between power consumption and communication responsiveness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the UE based on energy status. The UE monitors its energy status and adjusts the power state parameter accordingly, switching between reduced power state and non-reduced power state to optimize the trade-off between power consumption and communication service quality.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If the UE monitors energy status continuously, then power state selection accuracy is improved, but additional power consumption increases

Engineering Contradiction:

Improveenergy status monitoring accuracyVSAvoidmonitoring power consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The UE performs self-monitoring of its energy status using its own power management capabilities. The UE autonomously determines its energy status and selects appropriate power states without requiring external monitoring infrastructure, enabling accurate energy status detection while minimizing additional power consumption through efficient self-management.

Inventive Principle:

Principle #25Self-service
