Repeater Gain Bypass Using UE Signal Strength Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current repeaters face challenges in effectively amplifying wireless signals without introducing excessive noise, particularly when downlink signals have high power, and struggle to adjust gain based on user equipment needs to maintain signal quality and compliance with regulatory thresholds.
Innovation Solution
A repeater system that adjusts gain dynamically based on user equipment needs by measuring signal strength indicators and threshold values, reducing or bypassing amplification when signal strength is above a certain threshold to prevent noise introduction and ensure regulatory compliance, using a combination of amplifiers, attenuators, and path activation/deactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the repeater amplifies downlink signals with high power, then the signal strength received by the wireless device is improved, but excessive noise is introduced into the communication system
Solution Approach 1:
The repeater dynamically adjusts the gain of its amplifiers based on real-time measurements of downlink signal strength from the wireless device. When the signal strength indicator exceeds a threshold, the repeater reduces or bypasses amplification, preventing noise introduction while maintaining signal quality. This dynamic adaptation resolves the contradiction between providing strong signals and avoiding noise.
Solution Approach 2:
The system implements a feedback mechanism where the wireless device measures the downlink signal strength indicator and communicates this information back to the repeater. The repeater uses this feedback to adjust its amplification gain, reducing amplification when the signal is already strong enough. This closed-loop control prevents noise introduction while maintaining adequate signal strength.
2Device complexity
If the repeater uses fixed gain amplification, then the implementation is simple, but the repeater cannot adapt to varying user equipment needs and signal conditions
Solution Approach 1:
The repeater transitions from fixed gain to dynamic gain adjustment based on measured signal strength indicators. The system modifies its amplification behavior in real-time according to the wireless device's needs, improving adaptability while adding moderate complexity through gain control mechanisms.
Solution Approach 2:
The repeater changes the gain parameter of its amplifiers based on the measured downlink signal strength. By adjusting this key parameter dynamically, the system adapts to varying signal conditions and user equipment needs without requiring completely different system architectures.
3Power
If the repeater continuously amplifies all signals, then maximum signal strength is maintained, but regulatory thresholds may be exceeded and noise is increased
Solution Approach 1:
The repeater dynamically adjusts its amplification level based on real-time signal strength measurements, reducing or bypassing amplification when the downlink signal strength indicator exceeds a threshold. This prevents regulatory threshold violations while maintaining adequate signal strength for reliable communication.
Solution Approach 2:
The system takes preliminary action by measuring the downlink signal strength indicator before amplification and predicting potential regulatory violations. When the indicator exceeds the threshold, the repeater proactively reduces or bypasses amplification to prevent exceeding regulatory thresholds, rather than reacting after violation occurs.

AI summary
A technology is described for adjusting repeater gain based on user equipment need. A repeater can be configured to receive a downlink signal strength indicator value of a user equipment (UE) via a wireless connection of the UE with the repeater. The repeater can be further configured to select a threshold value for the downlink signal strength indicator value. The repeater can be further configured to reduce or bypass a downlink repeater gain level when the downlink signal strength indicator value is greater than the threshold value.
