Multi-Link Wi-Fi Operation Updates via a Secondary Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-link wireless communication, changes in operation information of a link can lead to delayed transmission of new operation information due to interference or reduced throughput, especially when data communication is involved.
Innovation Solution
A communication apparatus establishes multiple links with another device using different frequency channels and shares new operation information via a different link when changes occur, allowing for quicker dissemination of updated parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new operation information is transmitted via the link that needs to change operation information, then the link can maintain data communication continuity, but the transmission speed decreases and throughput is reduced
Solution Approach 1:
The patent uses a different link (second link) as an intermediary to transmit operation information about the first link. This mediator approach allows the operation information to be transmitted without interfering with the data communication on the original link, thus maintaining both communication continuity and transmission speed.
2Device complexity
If new operation information is transmitted via the link that needs to change operation information, then the transmission path remains simple, but interference from other apparatuses causes delayed transmission
Solution Approach 1:
The patent introduces a second link as an intermediary transmission path for operation information. This second link experiences less interference from other apparatuses, allowing operation information to be transmitted more quickly without increasing overall system complexity.
Solution Approach 2:
The patent transitions from a single-dimensional transmission approach (using the same link for both data and operation information) to a multi-dimensional approach by establishing multiple links with different frequency channels, allowing operation information to bypass interference on the original link.
3Productivity
If multiple links are established with different frequency channels, then operation information can be shared more efficiently, but the device complexity increases
Solution Approach 1:
The patent segments the communication function by dividing it into multiple independent links with different frequency channels. Each link can handle specific tasks (data communication or operation information transmission), improving overall efficiency while keeping individual link management relatively simple.

AI summary
A communication apparatus includes an establishment unit configured to establish a first link and a second link with another communication apparatus in a plurality of frequency channels where wireless communication compliant with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard is performed, and a notification unit configured to, in a case where information about operation of the first link established by the establishment unit is changed, notify the other communication apparatus of the changed information about the operation of the first link via the second link.
