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 UE beam management by generating and transmitting UE broad beams, allowing simultaneous testing of multiple UEs across different frequency ranges, and determining errors at the base station.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

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

Engineering Contradiction:
Improvebeam direction 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 multiple beam directions through signal processing and simulation techniques. Instead of physically creating multiple antenna panels for different beam directions, the system creates virtual copies of beam scanning behavior by processing signals to simulate what multiple antennas would detect, thereby achieving beam management testing functionality with minimal physical hardware

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The single fixed broad beam antenna performs multiple functions that would traditionally require separate specialized components. It simultaneously handles signal transmission, reception, and emulation of multiple beam directions across different frequency ranges, making one antenna panel serve the role of what would otherwise require multiple specialized antenna panels

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

2Reliability

If active antenna panels are used for beam management testing, then beamforming characteristics can be tested, but resource consumption increases

Engineering Contradiction:
Improvebeam management testing accuracyVSAvoidcomputing and networking resources
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system uses the single fixed broad beam antenna to serve multiple testing purposes simultaneously. By processing signals from this single antenna to emulate multiple UE beam scanning scenarios, the system makes the antenna self-sufficient for what would otherwise require multiple dedicated testing resources, reducing overall computing and networking resource consumption while maintaining testing reliability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent combines multiple beam management testing functions into a single antenna system. By merging the capabilities of what would be separate antenna panels into one unified system with signal processing, the patent reduces resource duplication and optimizes computing and networking resource utilization while maintaining comprehensive beam management testing capability

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If multiple UEs are emulated simultaneously, then testing throughput increases, but beam scanning coherence requirements increase complexity

Engineering Contradiction:

Solution Approach 1:

The system emulates multiple UE beam scanning processes using a single physical antenna through virtual signal processing. Each emulated UE's beam scanning behavior is created as a virtual copy processed through software algorithms, allowing multiple UEs to be tested simultaneously without requiring multiple physical antennas to maintain coherence, thereby simplifying the system while increasing productivity

Inventive Principle:
Principle #26Copying
