Solution Overview

Problem

Current beam management processes for 5G NR require expensive active antenna panels, which are narrow band and inefficient for multiple band or full band coverage, leading to resource waste and delays in UE attachment procedures.

Innovation Solution

A device with a single fixed broad beam antenna emulates 5G NR beam scanning processes, generating UE broad beams to cover various bands and frequencies, allowing simultaneous testing of multiple UEs and identifying errors at a base station.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If active antenna panels are used for beam management, then beam scanning capability is achieved, but device cost and complexity increase significantly

Engineering Contradiction:
Improvebeam scanning capabilityVSAvoidantenna panel complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses a single fixed broad beam antenna to emulate or simulate the functionality of complex active antenna panels. Instead of using multiple active antenna elements that physically perform beam scanning, the system creates a simplified copy or simulation of the beam scanning effect through signal processing and emulation techniques, thereby achieving the same functional outcome with much lower complexity

Inventive Principle:
Principle #26Copying

Solution Approach 2:

A single fixed broad beam antenna is designed to perform multiple functions that traditionally required complex active antenna panels. The antenna serves as both the physical radiating element and the basis for emulating various beam scanning patterns, making the system universally applicable for different beam management scenarios without requiring specialized hardware for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If narrow band active antenna panels are used, then beam management is achieved, but resource efficiency decreases for multiple band coverage

Engineering Contradiction:
Improvebeam management reliabilityVSAvoidresource efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The single fixed broad beam antenna is designed to handle multiple frequency bands and beam scanning scenarios universally. Instead of requiring separate narrow band active antenna panels for each band, this universal antenna structure can emulate beam scanning across multiple bands, significantly improving resource efficiency while maintaining beam management reliability through software-defined beamforming techniques

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If traditional beam scanning processes are used, then beam selection is achieved, but UE attachment procedure delays occur

Engineering Contradiction:
Improvebeam selection accuracyVSAvoidUE attachment delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary emulation of beam scanning patterns and pre-calculates beam characteristics before actual UE attachment. By preparing beam emulation data and patterns in advance, the system reduces the time required during the actual attachment procedure while maintaining accurate beam selection through pre-computed beamforming weights and emulation results

Inventive Principle:
Principle #10Preliminary action
