Solution Overview

Problem

In the new radio (NR) system, there is a need for efficient handling of measurement configuration and reporting between base stations and user equipment to manage measurement bandwidth and location on carriers, which is not adequately addressed by existing technologies.

Innovation Solution

A communication device and method where a base station transmits a measurement configuration to user equipment, specifying the allowed measurement bandwidth and its location on a carrier, and receives a measurement report based on reference signals within that bandwidth, enabling accurate measurement and potential handover operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement configuration is transmitted without specifying bandwidth and location, then the system is simpler, but measurement precision and system performance deteriorate

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by specifying the measurement bandwidth and its location on the carrier in the measurement configuration. Instead of uniform measurement across the entire carrier, the configuration identifies a particular bandwidth portion (e.g., specific resource blocks) where measurements should be performed. This localized measurement approach improves measurement precision for critical bandwidth regions while avoiding unnecessary measurements elsewhere, thus resolving the contradiction between measurement precision and device complexity.

Inventive Principle:
Principle #3Local quality

2Productivity

If measurement bandwidth is increased to improve system capacity, then more data can be measured, but device complexity and processing requirements increase

Engineering Contradiction:
Improvesystem capacityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the essential measurement information by identifying and configuring only the specific bandwidth portion that is critical for system capacity assessment. Instead of requiring measurements across the entire carrier bandwidth, the measurement configuration extracts and specifies only the relevant bandwidth segments (e.g., resource blocks carrying critical reference signals). This extraction approach enables effective system capacity monitoring while reducing device complexity and processing requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If measurement configuration specifies detailed bandwidth and location information, then measurement accuracy improves, but signaling overhead increases

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidsignaling overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies partial action by providing measurement configuration information that is sufficient for accurate measurements without being excessive. The measurement configuration specifies the necessary bandwidth and location details (such as resource block assignments and carrier frequencies) required to achieve measurement accuracy, but does not include redundant or overly detailed information. This partial information approach achieves the needed measurement precision while minimizing signaling overhead in the RRC messages.

Inventive Principle:
Principle #16Partial or excessive action
