Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent uses a software-defined radio (SDR) platform to generate and process synchronization signal blocks (SSBs) that replicate actual 5G base station signals. This software-based copying approach eliminates the need for expensive conventional test equipment while maintaining testing fidelity

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces conventional hardware-based test equipment with a software-defined radio system that uses programmable processors to generate, transmit, and analyze millimeter wave signals. This substitution of mechanical/electronic systems with software-controlled systems dramatically reduces cost while maintaining functionality

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

Solution Approach 1:

The patent replaces bulky conventional test equipment with a compact software-defined radio platform that integrates signal generation, processing, and analysis in a single portable device. The use of software-controlled FPGA or processor-based architecture enables miniaturization while maintaining full functionality

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The software-defined radio platform is designed to perform multiple functions including SSB generation, signal transmission, reception, and analysis within a single device. This multi-functionality eliminates the need for multiple separate test equipment components, reducing overall device volume

Inventive Principle:

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent employs efficient signal processing algorithms and adaptive processing modes that adjust computational intensity based on actual testing requirements. By dynamically changing processing parameters rather than always using maximum-capacity hardware, the system maintains signal processing capability while minimizing power consumption

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The software-defined radio platform implements selective signal processing that activates only the necessary processing functions for each specific testing scenario. Rather than continuously operating high-power processors and ADCs at full capacity, the system activates only the partial action needed for each test, reducing overall power consumption

Inventive Principle:

Solution Approach 1:

The patent implements automated testing and calibration routines that enable the system to perform self-diagnosis and self-optimization without requiring expert technicians. The software automatically configures test parameters, executes measurement sequences, and generates optimization recommendations, eliminating the need for on-site expert intervention and reducing deployment time while maintaining testing accuracy

AI summary

A repeater system includes a first repeater device that includes a first processor that sets the first repeater device as a source of a Synchronization Signal Block (SSB) signal independent of gNB. The first processor generates a pseudo-SSB signal before establishing any connection with the gNB in a pre-connection stage. The first processor further steers the pseudo-SSB signal across multiple directions to cover a sector of the first repeater device when the first repeater device is set as the source of the SSB signal. The first processor receives feedback including a plurality of signal assessment parameters from a second repeater device based on the pseudo-SSB signal received at the second repeater device. The first processor pre-calibrates the first repeater device and establishes a wireless link with the second repeater device in the pre-connection stage independent of the gNB, based on the feedback received from the second repeater device.
