Solution Overview

Problem

Current wireless communication systems face inefficiencies in beam management and alignment, particularly in millimeter-wave frequencies, due to harsh propagation conditions and the lack of standardized mechanisms for coordinating beam correspondence between devices, leading to suboptimal link performance.

Innovation Solution

The proposed solution involves influencing the behavior of network nodes, such as user equipment (UE) and base stations, by modifying their response to stimuli through sensitivity matrices, allowing for coordinated beam selection and alignment, even in harsh propagation conditions, by altering the criteria used for beam correspondence procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam correspondence procedures are implemented without standardized coordination mechanisms, then device autonomy is maintained, but beam alignment performance deteriorates in millimeter-wave conditions

Engineering Contradiction:

Improvebeam alignment performanceVSAvoidcoordination mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent modifies the criterion parameters used by network nodes for beam correspondence procedures. By changing the parameters that devices use to select response beam patterns, the system achieves coordinated beam alignment without requiring complex standardized coordination mechanisms. The network node receives a signal to influence these criteria and adjusts them accordingly, improving beam alignment performance while maintaining relatively simple device operation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If network nodes use default beam selection criteria, then device operation is simple, but link performance is suboptimal in harsh propagation conditions

Engineering Contradiction:

Improvelink performanceVSAvoidbeam selection operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the network node receives a signal from another network node indicating a request to influence the beam correspondence criterion. This feedback loop allows the system to adapt beam selection criteria based on actual propagation conditions and performance requirements, improving link performance while keeping the basic operation simple through automated adjustment.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If beam correspondence criteria are fixed, then device complexity is reduced, but adaptability to different propagation conditions deteriorates

Engineering Contradiction:

Improveadaptability to propagation conditionsVSAvoidcriterion adjustment complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the beam correspondence criterion dynamic rather than fixed. The network node can adjust its criterion for selecting response beam patterns based on received signals and propagation conditions. This dynamic adjustment capability allows the system to adapt to different millimeter-wave propagation conditions without requiring complex manual configuration or standardized coordination protocols.

Inventive Principle:

AI summary

A network node configured for wirelessly transceiving signals for operating in a wireless communication network is to form a response beam pattern responsive to a recognized stimulus of a stimulating node based on a criterion. The network node is to receive a signal indicated a request to influence the criterion and is to influence the criterion based on the request.
