Multi-Link Element Link ID Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless local area networks, existing systems face inefficiencies in transmitting multi-link information due to repeated transmission of common data across multiple stations, leading to increased signaling overhead.
Innovation Solution
A method where a transmitting multi-link device generates a multi-link element with a common information field and link identifier, allowing for the transmission of information related to all stations with a specific link identifier value, thereby reducing redundant signaling by grouping common information for multiple stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If common information is transmitted individually for each station, then information completeness is ensured, but signaling overhead increases
Solution Approach 1:
The patent merges common information for multiple stations into a single transmission by introducing a group identifier (link ID) that groups stations sharing common information. Instead of transmitting identical information separately to each station, the system transmits the information once with a group identifier, allowing all stations in that group to receive the same information efficiently.
Solution Approach 2:
The link ID field serves multiple functions: it identifies individual links, groups stations with common information, and enables efficient resource allocation. This universal identifier allows the system to handle both individual and group-based information transmission, reducing overall signaling overhead while maintaining information completeness.
2Productivity
If link ID field is extended to support group identification, then signaling efficiency improves, but device complexity increases
Solution Approach 1:
The link ID field is designed to be dynamic in its interpretation. The same field can represent either an individual link identifier or a group identifier depending on the context and value. This dynamic usage allows the system to adapt between individual and group-based transmission modes without requiring separate fields, thus improving signaling efficiency while limiting complexity increase.
Solution Approach 2:
The system changes the parameter interpretation of the link ID field based on its value. Certain values of the link ID indicate group membership rather than individual link identification. This parameter change approach allows the existing field structure to support both individual and group information transmission, improving efficiency without significantly increasing device complexity.

AI summary
In a wireless local area network system, a transmitting multi-link device (MLD) includes at least one transmitting station (STA). The transmitting STA generates a multi-link (ML) element and transmits the ML element. The ML element includes a common information field and information related to each transmitting STA. The information related to each transmitting STA includes a first link identifier (ID) field and a first link information field that includes information related to a transmitting STA operating in a link related to the first link field. The first link information field includes information commonly related to all transmitting STAs included in the transmitting MLD based on the first link ID field having a first value.
