Solution Overview

Problem

In wireless communication systems, networks face challenges in determining whether measurement results reported by user equipment (UE) are based on wideband or narrowband measurements, which affects network optimization and service efficiency, as the UE does not provide signaling to indicate the measurement type.

Innovation Solution

A method where the UE generates and includes measurement bandwidth information in measurement report messages to indicate whether the measurement results are from wideband or narrowband measurements, using a threshold bandwidth of six resource blocks to differentiate between the two, allowing the network to accurately assess and optimize services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the terminal reports measurement results without additional signaling, then the reporting process is simple and fast, but the network cannot determine whether the measurement is wideband or narrowband

Engineering Contradiction:
Improvemeasurement reporting speedVSAvoidmeasurement type information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent merges the measurement type information with the measurement result by including the bandwidth information (wideband or narrowband) directly within the measurement report message. This combination allows the network to identify the measurement type without requiring separate signaling, thus maintaining reporting speed while preventing information loss.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces bandwidth information as an intermediary element that bridges the gap between the measurement result and the network's need to understand the measurement type. This intermediary carries the necessary classification information (wideband/narrowband) within the existing reporting framework, enabling the network to distinguish measurement types without adding complex separate signaling procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the terminal provides detailed measurement bandwidth information, then the network can accurately optimize services, but the signaling overhead increases

Engineering Contradiction:
Improvenetwork optimization accuracyVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the essential bandwidth information (wideband or narrowband classification) from the complete measurement data, including only what is necessary for network optimization decisions. This extraction approach provides sufficient information for accurate service optimization while avoiding the transmission of redundant detailed bandwidth parameters, thus controlling signaling overhead.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the parameter representation by using a simplified bandwidth classification system (wideband/narrowband based on threshold comparison) rather than transmitting detailed bandwidth parameters. This parameter transformation maintains the reliability needed for network optimization while significantly reducing the complexity and overhead of the signaling required.

Inventive Principle:
Principle #35Parameter changes
