Access Point Downlink Link Provisioning with Preferred Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently provisioning downlink communication links, particularly in multi-link environments, where prioritizing communication links and reducing latency and overhead are crucial.
Innovation Solution
The system identifies preferred and non-preferred communication links based on channel conditions and provisions these links accordingly, using activation timeouts and offsets to manage contention and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication links are provisioned to meet QoS requirements, then reliability is improved, but device complexity and overhead increase
Solution Approach 1:
The patent segments communication links into preferred and non-preferred categories based on QoS requirements. The AP provisions only the necessary number of preferred links for each traffic flow, rather than provisioning all available links, thereby reducing complexity while maintaining reliability for critical traffic.
Solution Approach 2:
The patent applies different provisioning strategies to different links based on their quality characteristics. Preferred links receive full provisioning with activation timeouts, while non-preferred links are either not provisioned or provisioned with reduced parameters, optimizing resource usage according to local link conditions.
2Productivity
If activation timeout is extended for non-preferred links, then productivity is improved, but latency increases
Solution Approach 1:
The patent performs preliminary assessment of link quality before provisioning. By identifying preferred links in advance based on QoS requirements and current conditions, the system activates only those links that need immediate data transmission, avoiding the latency associated with activating non-preferred links.
Solution Approach 2:
The patent implements dynamic link provisioning where the set of preferred links can change based on evolving QoS requirements and network conditions. The AP can re-evaluate and re-provision links in real-time, allowing the system to adapt to changing conditions without being locked into static timeout configurations.
Data Source
AI summary
This disclosure provides methods, components, devices and systems for downlink provisioning with preferred links. Some aspects more specifically relate to a multi-link device (MLD) provisioning downlink communication links. In some examples, an access point (AP), which may be an example of an MLD, may identify communication links for a station (STA). The AP may identify preferred communication links based on receiving feedback information about channel conditions of a communication link. The AP may output data transmissions on the preferred communication links, as well as on non-preferred communication links with an offset. The AP may, additionally, or alternatively, output the data transmission on the non-preferred communication links based on failing to gain access to the preferred communication links, or based on receiving feedback information about channel conditions of the preferred communication links.
