Solution Overview

Problem

User devices in communication systems are restricted to having only one active antenna panel at a time, leading to challenges in maintaining effective beam correspondence and radio connectivity due to frequent panel switching, especially in scenarios with high switching rates.

Innovation Solution

Implementing a mechanism for user devices to determine and report antenna panel switching rates based on a moving averaging window, allowing network nodes to optimize communication parameters and improve connectivity by adjusting beam widths or other settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple antenna panels are used in user devices, then communication reliability and beam correspondence are improved, but device complexity increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The antenna system is segmented into multiple independent antenna panels, each capable of independent operation. This allows the device to divide the communication function across multiple panels, improving reliability through diversity while managing complexity by treating each panel as a separate unit that can be activated or deactivated independently based on channel conditions.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If antenna panel switching rate is increased, then adaptability to channel changes is improved, but beam correspondence and radio connectivity deteriorate

Engineering Contradiction:
Improveadaptability to channel changesVSAvoidradio connectivity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The antenna panel selection is made dynamic rather than static, allowing the system to adapt to changing channel conditions. The device can switch between panels based on real-time measurements of channel quality, beam correspondence metrics, and interference levels, optimizing performance while maintaining connectivity through intelligent adaptation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where the device measures channel conditions and beam correspondence for each antenna panel, then uses this information to determine optimal panel selection. This feedback loop allows the system to adapt to channel changes while maintaining stable connectivity by selecting panels that preserve beam correspondence.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If frequent antenna panel switching occurs, then communication flexibility is improved, but beam management and connection stability worsen

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system performs preliminary evaluation of beam correspondence and channel conditions for multiple antenna panels before making a switching decision. This preliminary action allows the device to predict the impact of potential panel switches on connection stability, enabling flexible adaptation while avoiding switches that would disrupt ongoing communications or break beam correspondence.

Inventive Principle:
Principle #10Preliminary action
