Solution Overview

Problem

In 5G NR systems, terminals face challenges in determining which bandwidth parts (BWP) to report measurement results for, as existing methods lack clarity on measurement configuration and reporting procedures.

Innovation Solution

A measurement reporting method and configuration method are introduced, where the terminal reports measurement results of a pre-defined BWP, and the network side device sends configuration information to determine the to-be-reported BWP and its measurement results, ensuring clear measurement reporting and improving system performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If dynamic and flexible bandwidth allocation is implemented with multiple BWPs configured for terminals, then system adaptability and energy-saving capability are improved, but measurement reporting determination complexity increases

Engineering Contradiction:

Improvebandwidth allocation flexibilityVSAvoidmeasurement reporting determination

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-defining specific BWPs (first pre-defined BWP and second pre-defined BWP) for measurement reporting purposes before actual measurement and reporting occur. The network side device configures these BWPs in advance through measurement configuration information, so that terminals already know which BWPs to measure and report on, eliminating the need for complex real-time determination logic.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the bandwidth parts into different categories: first pre-defined BWPs dedicated for measurement reporting and second pre-defined BWPs for other purposes. This segmentation allows the system to handle measurement reporting separately from other BWP operations, simplifying the determination process by clearly distinguishing which BWPs are relevant for measurement purposes.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If measurement reporting is based on existing configuration without pre-defined BWPs, then device complexity is reduced, but measurement precision and reporting accuracy deteriorate

Engineering Contradiction:

Improvemeasurement configurationVSAvoidmeasurement result accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

By pre-defining specific BWPs for measurement reporting through configuration information from the network side device, the patent ensures that terminals measure and report on the most relevant bandwidth parts. This preliminary definition of measurement targets improves measurement precision by focusing resources on critical BWPs rather than using generic measurement approaches.

Inventive Principle:

Principle #10Preliminary action
