AP MLD EML OM Notification Frame Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current activation/deactivation scheme for Enhanced Multi-Link Operating Modes in wireless communication networks is inefficient due to high overhead and lack of consideration for the overall network state, primarily driven by non-AP MLD constraints without accounting for the AP MLD's perspective.
Innovation Solution
The proposed solution involves the AP MLD spontaneously sending Enhanced Multi-Link Operating Mode Notification frames to propose activation, deactivation, or modification of EML OM, allowing for consideration of the overall network state, and enabling the non-AP MLD to request or modify these changes based on proposed link sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the non-AP MLD drives the activation/deactivation of EML OM, then the non-AP MLD can control its own operating mode, but the signaling overhead increases and the AP MLD's perspective on network state is not considered
Solution Approach 1:
The patent inverts the traditional control direction by enabling the AP MLD to initiate EML OM activation/deactivation proposals instead of only the non-AP MLD. This allows the AP MLD, which has comprehensive network state information, to make informed decisions about mode transitions while reducing unnecessary signaling from non-AP MLDs that lack global network visibility.
2Ease of operation
If the non-AP MLD sends EML OM Notification frames to activate/deactivate EML OM, then the non-AP MLD can respond to its own constraints, but the signaling overhead is high
Solution Approach 1:
The patent merges the control functions by allowing the AP MLD to initiate EML OM proposals, combining the benefits of non-AP MLD autonomy with AP MLD's global network perspective. This reduces redundant signaling while maintaining operational flexibility, as the AP MLD can propose mode changes based on overall network conditions rather than requiring each non-AP MLD to independently signal every constraint-based decision.
3Ease of operation
If the current EML OM activation scheme is used, then the non-AP MLD can manage its own links, but the overall network throughput and latency performance are not optimized
Solution Approach 1:
The patent implements feedback mechanisms where the AP MLD, having comprehensive knowledge of network state including overall throughput and latency conditions, can propose EML OM activation/deactivation decisions. This feedback loop ensures that mode transitions are made with full awareness of network performance metrics, optimizing productivity while maintaining distributed control through the non-AP MLD's ability to accept or modify proposals.

AI summary
In wireless networks implementing multilink transmissions, an AP MLD spontaneously sends an EML OM Notification frame defining a proposal or suggestion to activate or deactivate or modify an EML OM, optionally with a proposed set of EML Links. Taking advantage of this opportunity, the addressee non-AP MLD initiates an EML OM activation or deactivation as suggested. Upon receiving a request for EML OM activation or deactivation, the AP MLD may refuse the request and respond with another proposed set of links. The signalling in the requesting frames may be simplified by using a single one-bit field to implicitly activate or deactivate the single EML OM, either EMLSR or EMLMR mode, declared as supported during the association of the non-AP MLD.
