Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed anchor link is used in multi-link wireless communication, then the system structure is simple and easy to manage, but the communication quality cannot be optimized when channel conditions change
Solution Approach 1:
The patent implements dynamic anchor link switching by allowing the anchor link to change from one wireless signal processing unit to another based on real-time communication quality feedback. The system transitions from a static anchor link configuration to a dynamic one where the anchor link can be switched when channel conditions deteriorate, thereby maintaining reliable communication without excessive complexity through structured management protocols.
2Reliability
If the anchor link is frequently switched to optimize communication quality, then the communication reliability improves, but the control overhead and system complexity increase
Solution Approach 1:
The patent employs feedback mechanisms where communication quality metrics are monitored and used to trigger anchor link switching decisions. The system transmits control information including quality metrics and switching requests, allowing the network to make informed decisions about when to switch anchor links based on actual communication conditions rather than arbitrary or overly frequent switching, thus balancing reliability improvement with control overhead management.
3Productivity
If multiple wireless signal processing units are used to establish multi-link, then the data transmission capacity increases, but the management and coordination of these units becomes more complex
Solution Approach 1:
The patent segments the wireless communication system into multiple independent wireless signal processing units, each capable of handling specific data streams or links. By dividing the overall communication task across multiple units with clearly defined roles (including one designated as anchor link and others as non-anchor links), the system achieves increased data transmission capacity while managing complexity through modular organization and standardized coordination protocols.

AI summary
A base station according to an embodiment includes first and second wireless signal processing units, and a link management unit. The link management unit establishes a multi-link with a terminal apparatus by using the first and second wireless signal processing units, and sets an anchor link to be used in transmission and reception of control information regarding an operation of the multi-link. The link management unit transmits a first wireless frame requesting change of the anchor link by using the first wireless signal processing unit set to the anchor link, and changes the anchor link from the first wireless signal processing unit to the second wireless signal processing unit if either the first wireless signal processing unit or the second wireless signal processing unit receives a positive response from the terminal apparatus after the first wireless frame is transmitted.
