Solution Overview

Problem

Existing radio telecommunications networks face inaccuracies in link budget measurements due to changes in antenna configurations between measurement and data communication scenarios, leading to suboptimal beam selection and communication performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If antenna configuration changes are allowed between measurement and data communication scenarios, then beamforming performance and adaptability are improved, but link budget measurement accuracy deteriorates

Engineering Contradiction:

Improveantenna configuration flexibilityVSAvoidlink budget measurement accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by measuring the antenna configuration correction index (ACCI) in advance during a measurement scenario before actual data communication occurs. This pre-measured ACCI value is then stored and applied during beam selection procedures to compensate for any antenna configuration changes that may occur between measurement and data communication, thereby maintaining link budget accuracy while allowing antenna configuration flexibility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism - the antenna configuration correction index (ACCI) - that mediates between the measurement scenario and data communication scenario. The ACCI acts as a correction factor that translates antenna configuration changes into quantized values, allowing the system to account for configuration variations without compromising link budget measurement accuracy. This intermediary correction index enables the system to handle both adaptability and measurement precision requirements simultaneously.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If different antenna configurations are used for measurement and data communication, then beam selection accuracy is improved, but measurement and communication overhead increases

Engineering Contradiction:

Improvebeam selection accuracyVSAvoidmeasurement and communication overhead

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by transforming the complex antenna configuration parameters into a simplified quantized correction index (ACCI). Instead of transmitting and processing the full antenna configuration details during both measurement and data communication, the system uses this compressed ACCI parameter to represent the configuration differences. This parameter transformation reduces the overhead while maintaining the accuracy needed for beam selection procedures.
