Solution Overview
Problem
Current indoor distribution systems built on 4G technology face challenges in supporting 5G communication control, particularly in achieving ideal signal coverage and real-time network management due to high costs and complexity in upgrading to high-frequency bands and Multiple-In Multiple-Out (MIMO) configurations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If indoor distribution system uses 4G technology basis, then cost and complexity are reduced, but 5G communication control capability is insufficient
Solution Approach 1:
The patent divides the communication control function into two independent parts: a 5G chip for cell search and synchronization (5G capability) and a 4G chip for amplification control (4G infrastructure). This segmentation allows the system to leverage existing 4G hardware while adding 5G functionality, resolving the contradiction between maintaining low complexity and achieving 5G control capability.
Solution Approach 2:
The patent creates a multi-functional communication device where the 5G chip handles 5G-specific tasks (cell search, synchronization) while the 4G chip handles amplification control. Together they form a universal system that can operate in both 4G and 5G modes, enabling 5G communication control on the basis of 4G technology without requiring a complete system replacement.
2Area of stationary object
If repeater amplifies base station signal, then signal coverage is enhanced, but uplink and downlink timing coordination becomes complex
Solution Approach 1:
The patent implements timing coordination through feedback mechanisms where the 5G chip receives timeslot ratio information from the base station and feeds this back to the 4G chip. The 4G chip then uses this feedback information to control the amplification uplink and downlink timing, ensuring proper coordination without manual configuration.
Solution Approach 2:
The system performs self-configuration by automatically acquiring timeslot ratio information from the base station's broadcast signal and using it to control the amplification channels. This self-service approach eliminates the need for complex manual timing setup while ensuring proper uplink-downlink coordination across the extended signal coverage area.
