Beam Pattern Recovery via RF Path Failure Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G networks, beam pattern recovery is needed to address issues such as insufficient coverage, RF path failures, and the need for improved beam coverage and cell capacity, especially when RF paths operate abnormally, leading to beam distortion and reduced service quality.
Innovation Solution
A method and apparatus for recovering a beam pattern by generating a default beam pattern based on RF paths, detecting path failures, identifying beamforming parameters, and creating a recovered beam pattern that maintains similar coverage, involving communication nodes and servers that manage and transmit beamforming parameters to ensure optimal beam coverage.

Engineering Contradiction Analysis
1Area of stationary object
If beamforming is used to increase signal gain, then coverage is improved, but the system becomes vulnerable to RF path failures that distort the beam pattern
Solution Approach 1:
The system dynamically changes beamforming parameters (weights, phases, amplitudes) based on detected RF path conditions. When path failures are detected, the beamforming parameters are adjusted to compensate for the failed paths and restore the desired beam pattern, thus maintaining both coverage area and reliability
Solution Approach 2:
The system implements a feedback mechanism where the current beam pattern is monitored and compared against the desired pattern. When deviations are detected due to RF path failures, the system automatically adjusts beamforming parameters to correct the distortion, ensuring continuous maintenance of beam coverage and pattern stability
2Reliability
If hardware changes are made to fix RF path failures, then reliability is improved, but cost and maintenance complexity increase
Solution Approach 1:
Instead of physically replacing failed RF path hardware, the system creates a virtual copy or equivalent functional replacement through software-based beamforming parameter adjustments. This digital compensation approach achieves the same reliability improvement as hardware replacement but with significantly lower cost and complexity
Solution Approach 2:
The system replaces mechanical/hardware-based solutions (physical RF path replacement) with software-based beamforming parameter adjustment. This substitution eliminates the need for costly hardware changes while maintaining RF path reliability through intelligent signal processing
3Area of stationary object
If beamforming parameters are adjusted to compensate for path failures, then beam coverage is maintained, but system complexity increases
Solution Approach 1:
The system pre-calculates and stores alternative beamforming parameter sets that correspond to various RF path failure scenarios. When a failure is detected, the system quickly switches to the pre-prepared parameter set, maintaining beam coverage without requiring complex real-time calculations or sophisticated recovery mechanisms
