Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wireless signal processing units operating on different frequency bands are introduced, then communication speed and stability are improved, but device complexity increases
Solution Approach 1:
The base station and terminal are divided into multiple independent wireless signal processing units (first wireless signal processing unit, second wireless signal processing unit), each operating on different frequency bands. This segmentation allows parallel communication channels to be established, improving communication speed while managing complexity through modular design
Solution Approach 2:
Each wireless signal processing unit is designed with universal functionality to transmit and receive wireless signals on its designated frequency band. The link management unit provides multi-functional coordination, managing link states across multiple frequency bands, which improves stability without proportionally increasing complexity
2Productivity
If multiple channels are fully utilized for simultaneous data transmission, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
Multiple wireless signal processing units operate simultaneously on different frequency bands, enabling continuous data transmission across multiple channels. The link management unit maintains continuous monitoring and management of all link states, ensuring uninterrupted communication and improving overall efficiency
Solution Approach 2:
The system transitions from single-channel communication to multi-channel communication by adding the frequency band dimension. Each wireless signal processing unit operates on a different frequency band (first frequency band, second frequency band), creating parallel communication dimensions that improve efficiency without requiring sequential operations
3Reliability
If association processing is executed for multiple wireless signal processing units, then link stability is improved, but processing time increases
Solution Approach 1:
The link management unit performs preliminary management of link states for multiple wireless signal processing units before actual data transmission begins. Association processing is initiated and coordinated in advance across all frequency bands, ensuring link stability is established prior to communication, which reduces time loss during active transmission

AI summary
A base station of an embodiment includes first and second wireless signal processing units, and a link management unit. The first wireless signal processing unit is configured to transmit and receive wireless signals using the first channel. The second wireless signal processing unit is configured to transmit and receive wireless signals using a second channel different from the first channel. The link management unit manages link states of the first and second wireless signal processing units. Upon receiving a request for a multi-link from a terminal apparatus, the link management unit uses at least one of the first and second wireless signal processing units to execute association processing of the first wireless signal processing unit and association processing of the second wireless signal processing unit, and establishes a multi-link with the terminal apparatus.
