Multi-Link QoS Service Indication for Link-Level Loss Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a solution for indicating quality of service (QoS) in multi-link scenarios, making it difficult for receive devices to determine which link is causing poor QoS in low-delay services.
Innovation Solution
A method and apparatus for generating and sending quality of service measurement reports that include link indication information and quality of service information, such as the number of media access control service data units lost on each link, allowing accurate determination of QoS across multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multi-link transmission is implemented to reduce delay, then transmission speed is improved, but quality of service measurement and identification capability deteriorates
Solution Approach 1:
The patent segments the QoS measurement report into link-specific components, with each link having its own indication information and quality of service information. This allows precise identification of problematic links while maintaining the benefits of multi-link transmission for speed improvement.
Solution Approach 2:
The patent introduces a quality of service measurement report as an intermediary mechanism that carries link indication information and quality of service information between transmit and receive devices. This intermediary enables QoS measurement capability without interfering with the actual data transmission speed.
2Speed
If multi-link transmission is implemented to reduce delay, then transmission speed is improved, but reliability of QoS determination deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the receive device sends quality of service measurement reports back to the transmit device, containing link indication information and quality of service information. This feedback enables reliable QoS determination and allows for subsequent optimization of link selection and resource allocation.
Solution Approach 2:
By segmenting QoS information at the link level within the measurement report, the patent enables reliable determination of which specific link is causing poor QoS, while the multi-link transmission continues to provide high transmission speed through parallel communication paths.
3Measurement precision
If quality of service information for all links is collected and reported, then QoS determination accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the QoS measurement report into structured link-specific components, making the information organized and manageable. Each link has dedicated fields for indication information and quality of service information, which simplifies processing compared to unstructured comprehensive data.
Solution Approach 2:
The patent applies local quality by providing quality of service information specific to each link rather than aggregated data. This allows the system to focus processing resources on individual link characteristics, improving accuracy while managing complexity through targeted measurement rather than comprehensive analysis of all links simultaneously.
Data Source
AI summary
A method includes generating, by a non-access point multi-link device (NON-AP MLD), quality of service (QoS) requirement information of a traffic stream. The QoS requirement information comprises packet loss rate indication information and a delay bound. The packet loss rate indication information includes an acceptable maximum packet loss rate and a reference number of service data packets. The reference number of service data packets indicates a reference measurement number for counting the packet loss rate and is a number of data packets actually sent by the NON-AP MLD. The delay bound indicates an allowed maximum delay of the traffic stream. The method also includes sending, by the NON-AP MLD to an access point multi-link device (AP MLD), the QoS requirement information to be used for determining whether to establish the traffic stream.
