Repeater Leakage Reporting for Oscillation-Aware Gain Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face issues with repeater device oscillation due to excessive signal leakage and oscillation, leading to reduced signal quality, increased recovery errors, and data throughput reduction, especially in beamforming and millimeter wave communications.
Innovation Solution
A repeater device transmits a repeater leakage report indicating signal leakage metrics, allowing a network node to select a gain configuration that mitigates oscillation, thereby improving signal quality and data throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeater device amplifies pass-through signals to improve signal coverage, then signal quality improves, but signal leakage increases causing oscillation
Solution Approach 1:
The repeater device measures signal leakage metrics (such as self-interference levels) and feeds this information back to the network node. The network node uses this feedback to adjust the gain configuration, creating a closed-loop control system that dynamically balances signal amplification with leakage prevention.
Solution Approach 2:
The system dynamically adjusts the gain parameter of the repeater device based on measured signal leakage metrics. By changing the gain configuration in response to leakage conditions, the system optimizes the balance between signal quality and harmful signal leakage.
2Productivity
If repeater device uses high gain configuration to boost signal strength, then data throughput improves, but oscillation increases reducing reliability
Solution Approach 1:
The network node receives leakage reports from the repeater device and uses this feedback information to determine optimal gain configurations. This feedback mechanism ensures that high throughput is achieved only when signal leakage remains within acceptable thresholds, preventing oscillation-induced reliability degradation.
Solution Approach 2:
The gain configuration is made dynamic rather than static. The system continuously monitors signal leakage conditions and adjusts the gain in real-time, allowing the repeater to adapt between high-throughput modes and stable oscillation-free operation based on current network conditions.
3Reliability
If repeater device transmits leakage reports frequently to enable optimal gain configuration, then signal quality improves, but network overhead increases
Solution Approach 1:
Instead of continuous transmission, the repeater device transmits leakage reports periodically or at specific trigger events (such as when leakage metrics cross thresholds). This periodic reporting mechanism maintains signal quality while minimizing unnecessary network overhead and energy consumption.
