Solution Overview

Problem

Current wireless communication technologies, such as LTE and NR, face challenges in dynamically adapting user equipment (UE) parameters for power saving and efficient resource management, particularly in scenarios where feedback mechanisms are limited or unreliable, leading to uncertainties in UE configuration and potential power consumption inefficiencies.

Innovation Solution

Implementing a dynamic UE parameter adaptation status report mechanism, where a base station (BS) sends an indication to the UE to transmit a report on its configured parameters, allowing synchronization of adaptation status and enabling dynamic updates to reduce power consumption and improve latency in communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If dynamic UE parameter adaptation is implemented without reliable feedback mechanisms, then power saving and resource management efficiency are improved, but configuration accuracy and reliability deteriorate due to uncertainties in UE configuration status

Engineering Contradiction:

Improvepower consumptionVSAvoidconfiguration accuracy

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the UE sends a status report message to the BS indicating whether it has successfully applied the received UE parameter adaptation. This feedback loop allows the BS to verify configuration status and retransmit or adjust parameters as needed, ensuring reliable configuration while maintaining dynamic adaptation capabilities for power saving.

Inventive Principle:

Principle #23Feedback

2Reliability

If frequent status reports are transmitted to ensure accurate synchronization, then configuration accuracy and reliability are improved, but signaling overhead and network resource consumption increase

Engineering Contradiction:

Improvesynchronization accuracyVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The status report transmission is configured periodically or event-triggered rather than continuously. The UE transmits status reports at scheduled intervals or when specific events occur (e.g., parameter application status changes), balancing synchronization accuracy with reduced signaling overhead compared to continuous reporting.

Inventive Principle:

Principle #19Periodic action

3Adaptability or versatility

If UE parameters are dynamically adapted without verification mechanisms, then adaptability and responsiveness are improved, but loss of information occurs due to BS unawareness of UE configuration status

Engineering Contradiction:

Improveparameter adaptation capabilityVSAvoidconfiguration status information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The BS receives explicit feedback from the UE through status report messages that indicate whether the UE has successfully applied the adapted parameters. This feedback mechanism prevents information loss by ensuring the BS is always aware of the UE's configuration status, enabling informed decisions for subsequent parameter adaptations.

Inventive Principle:

Principle #23Feedback
