Dynamic Beamforming Disablement for Fading Channel Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless telecommunications networks do not dynamically disable beamforming of a frequency band based on fading levels, leading to potential interference and reduced channel quality for user devices.
Innovation Solution
Implementing a method to dynamically disable beamforming of a frequency band when its fading channel measurement exceeds a threshold, and reconnect user devices to a different frequency band with better channel conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beamforming functionality is enabled on a frequency band, then network capacity and coverage are improved, but channel quality deteriorates when fading occurs above threshold levels
Solution Approach 1:
The patent implements dynamic beamforming enablement/disablement based on real-time fading channel measurements. The system transitions from a static beamforming configuration to a dynamic one where beamforming is enabled when channel conditions are good and disabled when fading exceeds threshold levels, thereby adapting to changing channel conditions to maintain optimal channel quality while preserving network capacity when possible
Solution Approach 2:
The system changes the operational parameter of beamforming (enabled/disabled state) based on fading channel measurements. When the fading channel measurement exceeds a predetermined threshold, the system changes the beamforming parameter from enabled to disabled, directly addressing the contradiction by adjusting system parameters in response to measured channel conditions
2Reliability
If beamforming is continuously enabled, then user device connectivity is maintained, but interference increases due to fading channel conditions
Solution Approach 1:
The patent implements a feedback mechanism where fading channel measurements are continuously monitored and used to control beamforming operation. The system measures the fading channel, compares it to a threshold, and adjusts beamforming accordingly - creating a closed-loop control system that reduces interference by disabling beamforming when fading conditions indicate potential interference problems while maintaining connectivity
Solution Approach 2:
The system uses fading channel measurements (which indicate problematic conditions) as a trigger to disable beamforming, thereby converting the harmful effect of fading into a beneficial control signal that prevents interference. By detecting when fading exceeds thresholds, the system proactively disables beamforming to avoid generating interference, turning a channel impairment into a protective mechanism

AI summary
Methods and systems are provided for dynamically disabling beamforming functionality of one or more frequency bands. For example, a frequency band may have beamforming enabled. One or more user devices may be connected to the frequency band having beamforming enabled for access to a wireless telecommunications network. User devices connected with the frequency band may be at various locations of a network cell of the wireless telecommunications network (e.g., a cell center, middle cell, cell edge). Fading information may be received by one or more of the user devices connected with the frequency band. One or more fading channel measurements of the first frequency band may be above a threshold. In some embodiments, a fading channel measurement of the first frequency band is higher than another available frequency band having beamforming enabled. As such, beamforming of the first frequency band can be dynamically disabled.
