Reception MLD MAC Address Profiles for Non-Associated Link Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased number of spatial streams in next-generation WLAN systems, such as IEEE 802.11be or EHT, requires improved signaling techniques to enable frame exchange between non-associated stations (STAs) for efficient communication.
Innovation Solution
A method and apparatus for receiving a MAC address of another STA in a multi-link device (MLD) through an ML element, allowing frame exchange on non-associated links by including the MAC address in a profile field of the ML element, which can be set to include or exclude the address based on specific information settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If MAC addresses of other STAs are not included in the ML element, then the signaling overhead is reduced, but frame exchange between non-associated STAs on non-associated links cannot be enabled
Solution Approach 1:
The patent applies preliminary action by including MAC addresses of other STAs in the ML element during the initial association phase. This allows receiving STAs to have the necessary address information available before attempting frame exchange on non-associated links, enabling direct communication without requiring additional signaling overhead during actual data transmission.
2Adaptability or versatility
If MAC addresses are included in the profile field of ML element, then frame exchange on non-associated links is enabled, but the size of the ML element increases
Solution Approach 1:
The patent applies local quality by selectively including MAC addresses only in the profile fields of STAs that require communication on non-associated links. Not all STA profiles need to contain MAC addresses - only those whose MAC addresses are needed for frame exchange. This selective approach enables the necessary functionality while minimizing the overall size increase of the ML element.
3Productivity
If the number of spatial streams is increased, then communication throughput is improved, but the complexity of signaling techniques increases
Solution Approach 1:
The patent applies merging by combining multiple pieces of information into the ML element structure. MAC addresses of multiple STAs, along with their profile information, are merged into a single standardized element that can be processed uniformly by receiving STAs. This consolidation simplifies the signaling technique complexity despite the increased number of spatial streams, as the ML element provides a unified mechanism for managing multiple STAs and their communication parameters.

AI summary
Proposed are a method and an apparatus for receiving an MAC address of another STA within a reception MLD in a wireless LAN system. Specifically, the reception MLD receives an ML element from a transmission MLD through a first link. The reception MLD decodes the ML element. The ML element includes common information and link information. The link information includes a profile field of the second transmission STA. The profile field of the second transmission STA includes first information relating to whether an MAC address of the second transmission STA exists. If the first information is configured to be 1, the profile field of the second transmission STA includes the MAC address of the second transmission STA.
