Solution Overview
Problem
Current repeaters introduce excessive noise into the wireless communication system when amplifying downlink signals with high power, and there is a need to adjust gain levels to minimize noise interference while ensuring optimal signal quality.
Innovation Solution
A repeater system that adjusts gain based on user equipment needs by receiving downlink signal strength indicators and reducing or bypassing gain levels when signal strength exceeds a threshold, using machine-readable storage mediums with instructions to execute this adjustment, and employing amplifiers and attenuators in downlink and uplink paths to optimize signal amplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the repeater amplifies downlink signals with high gain to improve signal quality for user equipment, then the signal strength received by the user equipment is improved, but excessive noise is introduced into the wireless communication system
Solution Approach 1:
The repeater dynamically adjusts its gain level based on the measured signal strength from the base station and the determined distance to user equipment. When the base station signal is strong or UE is close, gain is reduced or bypassed. When signal is weak or UE is far, gain is increased. This dynamic adjustment resolves the contradiction by adapting the amplification level to current conditions, providing sufficient signal enhancement only when needed while minimizing noise introduction when the signal is already strong.
Solution Approach 2:
The system changes the gain parameter of the amplifier based on measured signal strength and calculated distance. The gain level is adjusted as a variable parameter rather than being fixed, allowing the repeater to optimize the balance between signal quality improvement and noise minimization by modifying the amplification factor according to real-time conditions.
2Area of stationary object
If the repeater uses fixed high gain amplification to ensure signal quality for all user equipment, then signal coverage is improved, but noise interference increases for user equipment close to the base station
Solution Approach 1:
The repeater implements dynamic gain adjustment that adapts to the spatial distribution of user equipment. By measuring signal strength and determining distance, the system varies the amplification level in real-time, providing high gain when needed for distant equipment while reducing gain when equipment is close to the base station, thus maintaining wide coverage without excessive noise interference.
Solution Approach 2:
The system applies different gain levels to different spatial regions or user equipment based on their distance from the base station. User equipment closer to the base station receives lower gain or bypassed amplification, while distant equipment receives higher gain. This localized quality adjustment ensures each user receives appropriate signal enhancement without contributing to unnecessary noise interference in the overall system.
3Object-generated harmful factors
If the repeater reduces gain levels to minimize noise introduction, then noise interference is reduced, but signal quality may deteriorate for user equipment far from the base station
Solution Approach 1:
The repeater dynamically adjusts gain based on real-time measurements of base station signal strength and calculated distance to user equipment. This ensures that when user equipment is distant or the base station signal is weak, the repeater applies higher gain to maintain signal quality, while when equipment is close or the base station signal is strong, gain is reduced to minimize noise. The dynamic nature of the adjustment ensures signal quality is maintained where needed without introducing unnecessary noise elsewhere.
Solution Approach 2:
The system uses feedback from signal strength measurements and distance calculations to continuously adjust the amplifier gain. The repeater measures the downlink signal strength from the base station, determines the distance to user equipment, and uses this feedback information to optimize the gain setting. This feedback loop ensures that gain is adjusted to the appropriate level to maintain signal quality while minimizing noise introduction based on actual system conditions.
