Innovation Solution
A system and method for relaying communication using electronic devices with duplexer circuits to convert signals between overlapping frequency bands, enabling communication between devices and designated networks through Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD) techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency band conversion is implemented using traditional methods, then communication relay is achieved, but device complexity increases due to multiple separate communication circuits
Solution Approach 1:
The patent combines multiple communication circuits (first communication circuit for first frequency band, second communication circuit for second frequency band) into a single integrated communication device. The transceiver unit shares common components between frequency bands, merging previously separate circuits into one unified structure that reduces overall device complexity while maintaining the ability to perform frequency band conversion for communication relay
Solution Approach 2:
The integrated communication device is designed to perform multiple functions: it can operate in the first frequency band, convert to the second frequency band, and relay communications. The transceiver unit serves as a universal component that handles both frequency bands, making the device multi-functional rather than requiring separate dedicated circuits for each frequency band
2Productivity
If overlapping frequency bands are used for communication relay, then communication efficiency is improved, but signal interference increases between frequency bands
Solution Approach 1:
The patent applies local quality by selectively managing frequency band usage in different operational contexts. The processing unit determines whether to use overlapping frequency bands or non-overlapping frequency bands based on specific communication scenarios, applying different frequency strategies locally rather than uniformly across all operations
Solution Approach 2:
The communication device dynamically adjusts its frequency band selection and conversion operations based on real-time conditions. The processing unit makes adaptive decisions about which frequency band to use for transmission and reception, changing operational parameters dynamically to optimize communication efficiency while minimizing interference based on current network conditions

AI summary
A system and a method for relaying communications with a designated network are provided. The first electronic device for relaying communication with the designated network includes a first communication circuit for receiving a first signal in a first frequency band from the designated network, a transceiver for receiving the first signal in the first frequency band from the first communication circuit, and a second communication circuit which includes a second duplexer for receiving, from the transceiver, a first signal in a second frequency band, which is generated from the first signal in the first frequency band, and transmits the first signal in the second frequency band to a second electronic device. The first signal in the second frequency band is provided to a third duplexer corresponding to a third frequency band included in the second electronic device. A partial frequency region in the second frequency band overlaps with the third frequency band.
