Solution Overview

Problem

Current wireless communication systems, particularly in 5G NR, face sub-optimal performance due to fixed configurations of dual polarized antenna elements in antenna modules, which lead to increased complexity and reduced efficiency in dynamic polarization combinations.

Innovation Solution

1Reliability

If fixed configurations of dual polarized antenna elements are used, then device complexity is reduced, but communication performance deteriorates

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic polarization combining where the antenna system transitions from fixed to dynamic configuration. The UE determines polarization combinations based on measured signal strength from reference signals, allowing the system to adapt to changing channel conditions. This dynamic approach resolves the contradiction by enabling performance optimization without requiring complex manual configuration, as the system self-adjusts based on environmental feedback.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the polarization parameter dynamically by selecting different polarization combinations (e.g., horizontal-horizontal, vertical-vertical, horizontal-vertical) based on measured signal strength. The system evaluates multiple polarization parameter configurations and selects the optimal one, thereby improving communication performance without permanently increasing device complexity through fixed complex configurations.

2Reliability

If dynamic polarization combination is implemented, then signal strength is improved, but device complexity increases

Engineering Contradiction:
Improvesignal strengthVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies partial action by evaluating only necessary polarization combinations based on measurement results. Instead of exhaustively testing all possible configurations, the system performs measurements on reference signals and selects from predefined polarization combinations, reducing processing complexity while still achieving signal strength improvement through targeted dynamic adjustment.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system implements feedback mechanisms where the UE measures reference signal strength from different polarization combinations and uses this feedback to determine the optimal configuration. This feedback-driven approach improves signal strength by adapting to actual channel conditions while managing processing complexity through efficient measurement and selection algorithms rather than exhaustive optimization.

Inventive Principle:
Principle #23Feedback

3Productivity

If antenna elements are deactivated based on measurements, then communication efficiency is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The antenna system performs self-service by automatically deactivating suboptimal antenna elements based on measured signal strength from reference signals. The UE independently determines which polarization combinations yield the best performance and configures the antenna elements accordingly, improving communication efficiency without requiring complex external control mechanisms. The system serves itself by making autonomous decisions based on environmental feedback.

Inventive Principle:
Principle #25Self-service

AI summary

Method and apparatus for dynamic polarization combining. The apparatus identifies a first polarization of a first set of antenna elements on a first side of an antenna module having two or more sides. The apparatus identifies a second polarization of a second set of antenna elements on a second side of the antenna module. The apparatus determines, for an antenna layer, a dynamic polarization combination between the first set of antenna elements having the first polarization with the second set of antenna elements having the second polarization. The apparatus communicates with a network node via the antenna module based on the dynamic polarization combination.
