Solution Overview

Problem

In wireless communication systems, user equipment (UE) currently performs early measurement reporting (EMR) measurements continuously, consuming battery power and resources, even when not required, which can lead to unnecessary power consumption and unreliable measurement results, especially when transitioning between RRC states.

Innovation Solution

The implementation of an enhanced early measurement reporting (EMR) procedure where the UE determines its configuration for EMR and initiates measurements only when necessary, using cell reselection measurements as EMR measurements, and saving configurations to perform measurements after transitioning to an RRC_IDLE or RRC_INACTIVE state, allowing for efficient power conservation and reliable reporting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user equipment performs early measurement reporting measurements continuously, then measurement availability is improved, but battery power consumption increases

Engineering Contradiction:
Improvemeasurement availabilityVSAvoidbattery power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by transitioning from continuous static measurement to conditional dynamic measurement. The UE determines whether to perform EMR measurements based on current RRC state and network configuration, adjusting measurement behavior dynamically rather than continuously operating.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements periodic measurement reporting where the UE reports measurements at specific intervals or trigger events rather than continuously. Measurements are performed periodically based on RRC state transitions and network indications, consuming power only when needed.

Inventive Principle:
Principle #19Periodic action

2Reliability

If user equipment performs early measurement reporting measurements continuously, then measurement reliability is improved, but measurement accuracy deteriorates due to unnecessary measurements

Engineering Contradiction:
Improvemeasurement reliabilityVSAvoidmeasurement accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent employs feedback mechanisms where the network provides indications to the UE about whether EMR measurements are required. The UE uses this feedback information to determine when to perform measurements, ensuring measurements are conducted only when necessary for accurate reporting.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by having the UE determine configuration status before performing measurements. The UE checks whether it is configured for EMR and whether measurements are needed based on current state, avoiding unnecessary measurements that would reduce accuracy.

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If user equipment saves configuration for later measurements, then power consumption is reduced, but measurement timing flexibility is limited

Engineering Contradiction:
Improvepower consumptionVSAvoidmeasurement timing flexibility
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent resolves this contradiction through dynamic measurement execution. While configurations are saved to reduce power consumption, the UE can still perform measurements dynamically when triggered by RRC state transitions or network indications, maintaining timing flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies self-service by having the UE autonomously determine when to execute saved measurements based on its own state and received indications. The UE manages its own measurement timing without external control, balancing power savings with operational flexibility.

Inventive Principle:
Principle #25Self-service
