Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If M-AP coordination schemes are implemented to enhance network performance and reliability, then network efficiency and user experience are improved, but device complexity increases due to the need for coordination mechanisms between access points
Solution Approach 1:
The patent introduces a coordination control frame as an intermediary mechanism that facilitates communication and parameter exchange between access points. This frame serves as a standardized mediator that carries coordination information, enabling M-AP coordination without requiring complex direct coordination protocols between APs, thus improving reliability while managing complexity through a structured intermediate format
2Productivity
If coordination control frames with user information fields are exchanged between access points, then transmission parameter coordination is enabled, but loss of information increases due to the additional overhead and potential for transmission errors
Solution Approach 1:
The coordination control frame incorporates feedback mechanisms where access points exchange transmission parameters and coordination information through standardized fields. This structured feedback loop enables accurate parameter coordination while minimizing information loss through defined field formats that ensure complete and consistent information exchange between APs
3Adaptability or versatility
If multiple user information fields are included in coordination control frames to support multiple access points, then adaptability increases for different M-AP scenarios, but device complexity increases due to the need to process and manage multiple fields
Solution Approach 1:
The coordination control frame is segmented into multiple user information fields, each dedicated to specific coordination parameters or access points. This segmentation allows the system to handle different M-AP scenarios adaptably by including or excluding specific fields as needed, while simplifying processing by dividing complex coordination data into manageable, purpose-specific segments that can be handled independently

AI summary
A multi-access point (M-AP) coordination method comprises receiving a coordination control frame, by a processor of a second access point (AP), wherein the coordination control frame is transmitted from a first AP, wherein the coordination control frame comprises at least one user information field for at least one shared AP, and each of the at least one user information field comprises an AP ID of a shared AP and coordination transmission parameters information of the shared AP; identifying, by the processor, the second AP as the shared AP if the AP ID of the second AP is in one user information field; and transmitting, by the processor, a packet during a transmission opportunity (TX OP) shared by the first AP based on the coordination transmission parameters information in the user information field containing the AP ID of the second AP.
