Solution Overview

Problem

In wireless communication systems, wireless devices face challenges in efficiently controlling relaxed measurement processes, which can lead to delays in setting up carrier aggregation (CA) and dual connectivity (DC) due to incomplete measurement results.

Innovation Solution

A method where a wireless device receives measurement configurations from a network, determines whether to perform relaxed measurements or no measurements based on satisfied relaxed measurement conditions, and selectively applies these conditions to specific frequencies not included in the idle or inactive state measurement configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a wireless device performs relaxed measurement to save power, then power consumption is reduced, but measurement results may be incomplete causing delays in CA and DC setup

Engineering Contradiction:

Improvepower consumptionVSAvoiddelay in CA and DC setup

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The measurement frequencies are segmented into two groups: frequencies included in idle mode measurement configuration and frequencies not included. Relaxed measurement conditions are applied only to the second group, while the first group maintains normal measurement requirements. This segmentation allows power saving on non-critical frequencies while ensuring timely measurement on frequencies important for fast CA/DC setup.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different measurement quality requirements are applied to different frequency groups. Frequencies in the idle mode measurement configuration maintain full measurement quality and timing requirements, while frequencies outside this configuration can utilize relaxed measurement conditions. This local differentiation ensures that critical frequencies receive adequate measurement attention while non-critical frequencies contribute to power savings.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If a wireless device performs measurement on all configured frequencies, then measurement completeness is improved, but power consumption increases

Engineering Contradiction:

Improvemeasurement completenessVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The set of all configured measurement frequencies is divided into two segments: those included in idle mode measurement configuration and those excluded. This segmentation enables selective application of measurement strictness, ensuring completeness on critical frequencies while reducing power consumption on non-critical frequencies through relaxed measurement conditions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different measurement quality levels are applied locally to different frequency groups. The first group (in idle mode configuration) receives high-quality full measurements, while the second group (not in idle mode configuration) receives relaxed measurements. This local quality differentiation maintains overall measurement effectiveness while reducing total power consumption.

Inventive Principle:

Principle #3Local quality

3Use of energy by moving object

If a wireless device applies relaxed measurement conditions to all frequencies, then power consumption is reduced, but setup time for CA and DC increases

Engineering Contradiction:

Improvepower consumptionVSAvoidsetup speed for CA and DC

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

Frequencies are segmented based on their inclusion in idle mode measurement configuration. The first segment (included frequencies) maintains normal measurement timing to support fast CA/DC setup, while the second segment (excluded frequencies) applies relaxed conditions for power savings. This segmentation prevents relaxed conditions from impacting critical setup operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different measurement quality and timing requirements are applied locally to different frequency groups. Critical frequencies (in idle mode configuration) maintain strict timing requirements to ensure fast CA/DC setup, while non-critical frequencies (not in idle mode configuration) use relaxed conditions. This local differentiation preserves productivity for critical operations while enabling power savings elsewhere.

Inventive Principle:

Principle #3Local quality

AI summary

A method and apparatus for controlling relaxed measurement in a wireless communication system is provided. A wireless device receives, from a network, a first measurement configuration including at least one of relaxed measurement conditions. A wireless device receives, from the network, a second measurement configuration including a frequency set to be measured in an idle state and/or an inactive state. A wireless device determines to perform a relaxed measurement or no measurement on at least one of frequency which is not included in the frequency set included in the second measurement configuration, based on that the at least one of the relaxed measurement conditions is met.
