AP Multi-Link Resource Provisioning for Latency-Sensitive Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to meet the strict latency, throughput, and timing requirements of low-latency applications like real-time gaming and augmented/virtual reality due to inefficient provisioning of communication links in multi-link devices.
Innovation Solution
A processing system in the AP MLD dynamically provisions either a single or multiple communication links based on latency, interference, and traffic load, and switches between these configurations as needed to optimize performance for individual STAs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple communication links are provisioned for all STAs, then throughput is improved, but latency requirements cannot be met due to congestion and interference
Solution Approach 1:
The patent applies local quality by differentiating link provisioning based on STA type and application requirements. Latency-sensitive STAs (e.g., XR devices) are provisioned with dedicated single links or prioritized multi-link configurations, while throughput-oriented STAs can utilize multiple links. This localized differentiation ensures that critical latency requirements are met without sacrificing overall network throughput capacity.
Solution Approach 2:
The patent implements dynamic link provisioning where the AP MLD continuously monitors network conditions, STA requirements, and link quality metrics. The system dynamically adjusts the number and configuration of provisioned links on demand, switching between single-link and multi-link modes based on real-time latency and throughput requirements, thereby resolving the contradiction between maintaining low latency and maximizing throughput.
2Productivity
If multiple communication links are provisioned, then data capacity is increased, but power consumption in STAs increases
Solution Approach 1:
The patent applies partial action by provisioning multiple communication links only to STAs that have explicit multi-link capability and require enhanced data capacity. Most STAs continue to operate on single links, consuming minimal power. This selective partial provisioning ensures that data capacity is increased only where necessary, while the majority of STAs maintain low power consumption levels.
3Productivity
If communication links are dynamically switched, then performance is optimized, but system complexity increases
Solution Approach 1:
The patent implements self-service through automated link provisioning and dynamic switching mechanisms. The AP MLD autonomously monitors network conditions, evaluates STA requirements, and performs link provisioning/switching decisions without manual intervention. This automation manages the inherent complexity internally while presenting a simplified interface to STAs, thereby achieving performance optimization without proportionally increasing observable system complexity.

AI summary
This disclosure provides systems and methods for provisioning resources in a wireless network. In some implementations, an apparatus obtains, from a first station (STA) on a first communication link associated with an access point (AP) multi-link device (MLD), a request for association all communication links of the AP MLD, and provisions either a single communication link or multiple communication links of the AP MLD for communications with the first STA based on at least one of a latency, a level of interference, or a traffic load associated with each of the communication links of the AP MLD. The apparatus generates a frame indicating whether the single communication link or the multiple communication links of the AP MLD are provisioned to the first STA for communications with the AP MLD, and outputs the frame for transmission to the first STA.
