MLD Statistics Sharing Negotiation for Latency Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks lack defined mechanisms for exchanging latency statistics information and capability information, which hampers the ability to manage and mitigate interference affecting latency-sensitive applications.
Innovation Solution
Implement mechanisms for requesting and sharing latency statistics reports between multi-link devices (MLDs) using solicited, unsolicited, and periodic modes, enabling better network adaptation and interference management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If statistics information sharing is implemented between MLDs, then network performance and latency management is improved, but device complexity and negotiation overhead increase
Solution Approach 1:
The patent implements a feedback mechanism where MLDs exchange capability information and statistics reports through standardized negotiation frames. The AP receives capability information from STAs, determines sharing eligibility, and exchanges statistics reports accordingly. This feedback loop enables adaptive network management while maintaining structured complexity through standardized protocols.
Solution Approach 2:
The patent creates a universal framework where the same negotiation mechanism serves multiple functions: capability assessment, statistics sharing eligibility determination, and report exchange. This multi-functional approach reduces overall system complexity by consolidating management functions into a single standardized procedure rather than requiring separate mechanisms for each function.
2Object-affected harmful factors
If latency statistics reports are exchanged proactively, then interference management is improved, but network overhead and processing time increase
Solution Approach 1:
The patent applies preliminary action by having MLDs exchange capability information during the association setup phase before actual data transmission begins. This preliminary capability assessment determines whether statistics sharing should be activated later, avoiding unnecessary processing time during active data transmission while still enabling proactive interference management when needed.
Solution Approach 2:
The patent implements periodic action through conditional statistics report exchange, where reports are transmitted at predetermined intervals or triggered by specific events rather than continuously. This periodic approach enables interference management at optimal moments while minimizing processing time and overhead during periods when interference is not critical.

AI summary
A station (STA) includes a processor configured to perform negotiation for statistics information sharing with an access point (AP). The STA also includes a transceiver operatively coupled to the processor. The transceiver is configured to, as part of the negotiation, transmit to the AP, a request frame indicating a request to receive statistics reports from the AP. The transceiver is also configured to, as part of the negotiation, receive, from the AP, a response frame acknowledging the request and indicating one of (i) acceptance of the request, (ii) rejection of the request, or (iii), a suggestion of an alternative proposal to the request.
