Solution Overview

Problem

The existing measurement gap configuration in LTE is inflexible and unable to accurately predict measurement gaps for user equipment (UE) with varying capabilities, particularly in 5G NR systems with flexible reference signal configurations, leading to inefficiencies in network communication.

Innovation Solution

A method for user equipment (UE) to obtain measurement-related information and configuration information from a network device, determining whether a measurement gap is required based on parameters like carrier, bandwidth part, and reference signal, and transmitting this information back to the network device for precise configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed measurement gap patterns are used in LTE, then the configuration is simple and standardized, but it cannot adapt to flexible reference signal configurations in 5G NR systems and varying UE capabilities

Engineering Contradiction:

Improveadaptability to flexible reference signal configurationsVSAvoidmeasurement gap configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic measurement gap configuration where the network device determines measurement gap requirements based on UE feedback. The UE reports its measurement capability and the network device dynamically decides whether to configure measurement gaps, allowing the system to adapt to different UE capabilities and reference signal configurations while maintaining operational simplicity through automated decision-making.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a feedback mechanism where the UE reports measurement-related information and capability to the network device. Based on this feedback, the network device determines whether measurement gaps are required and configures them accordingly. This feedback loop enables adaptive configuration that matches actual UE needs without requiring complex pre-definition for all possible scenarios.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If measurement gaps are configured for all UEs, then measurement accuracy is ensured, but resource consumption increases and network communication efficiency decreases

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidnetwork communication efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent applies local quality by configuring measurement gaps selectively for specific UEs based on their individual capabilities and measurement requirements. Instead of uniformly configuring gaps for all UEs, the network device evaluates each UE's reported measurement-related information and applies measurement gap configuration only where necessary, thereby maintaining measurement accuracy for requiring UEs while preserving network efficiency for others.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements partial action by configuring measurement gaps only for the subset of UEs that actually require them, rather than for all UEs. The network device determines which UEs need measurement gaps based on their capability reports and measurement configurations, applying the measurement gap treatment partially to achieve necessary measurement accuracy without the excessive resource consumption of universal configuration.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If the network device predicts measurement gaps for all UE capability scenarios, then complete coverage is achieved, but the prediction complexity and configuration overhead increase significantly

Engineering Contradiction:

Improvemeasurement gap configuration reliabilityVSAvoidnetwork device prediction complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by having the UE proactively report its measurement capability and measurement-related information to the network device before measurement gap configuration is needed. This advance reporting eliminates the need for the network device to predict and pre-configure measurement gaps for all possible UE capability scenarios, as the actual UE characteristics are already known when configuration decisions are made.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by enabling the UE to autonomously evaluate its own measurement requirements and report this information to the network device. The UE essentially serves itself by determining its own measurement gap needs based on its capability and the configured measurement parameters, reducing the prediction burden on the network device while ensuring reliable configuration decisions.

Inventive Principle:

Principle #25Self-service
