Multi-link Radio Frame Consolidating Management Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of links increases, sending management frames on multiple links becomes time-consuming and inefficient, particularly when advanced features like block acknowledgment (BA) or target wake time (TWT) are used.
Innovation Solution
A multi-link communication method where a radio frame carries at least two management frames generated by different stations working on various links, improving communication efficiency by consolidating frame transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If management frames are sent on each of the multiple links separately, then each link can be configured independently, but the time consumption increases and efficiency decreases
Solution Approach 1:
The patent combines multiple management frames that need to be sent on different links into a single radio frame. The first station generates a radio frame that includes multiple management frames generated by different stations working on different links, allowing all links to be configured simultaneously in one transmission instead of sequentially on each link.
Solution Approach 2:
The radio frame serves multiple functions simultaneously - it carries management frames for multiple different links within a single transmission. This multi-functional approach allows one transmission event to accomplish what would otherwise require multiple separate transmission events across different links.
2Ease of manufacture
If multiple management frames are sent separately on multiple links, then each frame can be processed independently, but communication efficiency is reduced
Solution Approach 1:
The patent merges multiple management frames into a single radio frame structure. The radio frame includes multiple management frames generated by different stations working on different links, allowing the receiving station to process all frames in one reception and processing cycle rather than sequentially across multiple links.
3Adaptability or versatility
If the number of links increases, then more communication bands are available, but the complexity of managing multiple management frames increases
Solution Approach 1:
The radio frame structure is designed to be universal and can accommodate management frames from multiple different links simultaneously. This multi-functional container approach allows the system to scale to more links and bands without proportionally increasing the complexity of frame management, as all frames are handled through a single unified structure.

AI summary
Embodiments of this application disclose a multi-link communication method and a related apparatus. The method includes: a first station sends, on a first link, a radio frame to a second station, where the first station is one of multiple stations included in a first multi-link device. The multiple stations included in the first multi-link device work on multiple links, and the multiple links include a first link on which the first station works. The radio frame includes at least two management frames, the at least two management frames are generated by at least two stations that work on different links in the first multi-link device, and the second station is one of multiple stations included in a second multi-link device.
