Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of 5G systems, particularly at millimeter wave bands, faces challenges in enhancing cell coverage due to severe signal fading. Traditional RF repeaters lack network-controlled operation, leading to suboptimal signal amplification and potential interference, which reduces network throughput.
Innovation Solution
The implementation of a communication method and system that enables network-controlled operation of RF repeaters by supporting information interaction between the network (base station) and the RF repeater. This allows for dynamic adjustment of antenna direction, amplification gain, and forwarding direction, optimizing signal transmission and reducing interference.

Engineering Contradiction Analysis
1Area of stationary object
If a traditional RF repeater is adopted to amplify and forward signals, then cell coverage is enhanced, but network throughput is reduced due to interference and lack of network control
Solution Approach 1:
The patent implements feedback mechanisms where the RF repeater reports received signal strength and quality information to the network side. The network uses this feedback to dynamically adjust the repeater's operation parameters, including amplification gain and forwarding direction, thereby optimizing both coverage enhancement and network throughput while reducing interference.
Solution Approach 2:
The patent transforms traditional static RF repeaters into dynamic network-controlled devices. The repeater's operation parameters such as amplification gain, antenna direction, and forwarding direction are made dynamically adjustable based on real-time network conditions and feedback information, allowing optimal performance adaptation.
2Device complexity
If manual configuration of antenna direction and forwarding direction is used, then device complexity is reduced, but signal transmission effectiveness is suboptimal
Solution Approach 1:
The patent enables the RF repeater to perform self-configuration and self-optimization. The repeater automatically acquires network control information, configures its own operation parameters including antenna direction and forwarding direction, and adjusts amplification gain without manual intervention, thereby reducing configuration complexity while improving signal transmission effectiveness.
Solution Approach 2:
The patent dynamically changes operation parameters of the RF repeater including antenna direction, beam width, forwarding direction, and amplification gain based on network conditions and feedback information. These parameter changes are automatically managed by the network-controlled system, optimizing signal transmission effectiveness.
3Device complexity
If traditional RF repeaters without communication function are used, then device complexity is reduced, but adaptability to network control is lost
Solution Approach 1:
The patent integrates multiple functions into the RF repeater, including signal amplification, signal forwarding, and communication functions for receiving network control information and reporting status. This multi-functionality approach maintains relative simplicity while adding network control adaptability, allowing the repeater to serve both as a signal relay and a network-controlled device.
