Solution Overview

Problem

In wireless communication networks, there is a lack of clear configuration for deriving and reporting beam level measurements for the serving cell during early measurements performed by a UE in RRC_IDLE or RRC_INACTIVE states, leading to ambiguity and potential misinterpretation of measurement information by the network.

Innovation Solution

A method is introduced where the UE receives a specific configuration for performing and reporting beam level measurements for the serving cell, allowing it to determine whether and how to derive these measurements based on provided settings, ensuring relevant and accurate reporting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the UE performs early measurements for neighboring NR frequencies without a clear configuration for serving cell beam level measurements, then the network can receive measurement information, but the measurement information may be misinterpreted or incomplete

Engineering Contradiction:

Improvemeasurement information completenessVSAvoidconfiguration complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The network node provides a configuration for beam level measurements for the serving cell before the UE transitions to connected state. This preliminary configuration ensures that when the UE performs early measurements in idle or inactive state, it knows exactly what to measure and how to report, preventing information loss or misinterpretation without adding complexity during the measurement execution phase

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The configuration includes parameters that guide the UE on how to derive and report beam level measurements. The network receives the measurement report and can verify it matches the configured parameters, providing feedback mechanism that ensures measurement information completeness and accuracy while maintaining clear configuration boundaries

Inventive Principle:

Principle #23Feedback

2Reliability

If the UE reports beam level measurements for the serving cell without clear configuration, then more measurement data is provided to the network, but unnecessary resource utilization and power consumption occur

Engineering Contradiction:

Improvemeasurement reporting accuracyVSAvoidUE power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network node configures the UE with specific parameters for beam level measurements (such as which beams to measure, reporting thresholds, and measurement types) before the UE enters idle or inactive state. This preliminary configuration ensures the UE only performs measurements that are actually needed, avoiding unnecessary energy consumption while maintaining reporting accuracy for the configured parameters

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The configuration allows the network to adjust measurement parameters dynamically based on network conditions and UE state. The UE can modify its measurement behavior according to the configured parameters (e.g., adjusting measurement frequency or depth), which optimizes the balance between measurement accuracy and power consumption without compromising reliability for the configured measurement types

Inventive Principle:

Principle #35Parameter changes

3Quantity of substance

If the UE performs beam level measurements for the serving cell during early measurements, then comprehensive measurement data is obtained, but the configuration ambiguity leads to potential misinterpretation by the network

Engineering Contradiction:

Improvemeasurement data quantityVSAvoidmeasurement data interpretability

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The configuration separates different types of measurements into distinct categories: beam level measurements for the serving cell and measurements for neighboring frequencies. Each category has its own specific parameters and reporting requirements. This segmentation ensures that when the UE reports comprehensive measurement data, the network can clearly distinguish between serving cell beam measurements and neighboring cell measurements, eliminating interpretability issues while maintaining complete measurement data

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The configuration includes explicit parameters that define how beam level measurements should be derived and reported. The network receives the measurement report and can verify it matches the configured parameters, providing feedback mechanism that ensures measurement information completeness and accuracy while maintaining clear configuration boundaries

Inventive Principle:

Principle #23Feedback
