Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies face inefficiencies in utilizing Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) transmissions due to varying packet traffic characteristics among client devices, leading to suboptimal throughput and resource utilization.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If client devices with different packet traffic characteristics are served by the same access point, then the access point can serve more diverse clients, but MU-MIMO transmission effectiveness deteriorates
Solution Approach 1:
The patent segments client devices into different groups based on their packet traffic characteristics (e.g., packet size, packet inter-arrival time). Each group is then served by a dedicated access point or wireless path, ensuring that clients with similar traffic patterns are grouped together. This segmentation enables effective MU-MIMO transmissions within each group while maintaining the ability to serve diverse client types across the network.
2Productivity
If traffic flows are grouped by similar characteristics, then spatial signal multiplexing can be implemented, but system complexity increases
Solution Approach 1:
The patent implements preliminary classification of traffic flows based on their characteristics (packet size, packet inter-arrival time, application type) before grouping them for MU-MIMO transmission. This preliminary action enables the system to pre-identify suitable candidates for spatial signal multiplexing, reducing the complexity of real-time traffic flow management while maximizing the benefits of grouped transmissions.
3Productivity
If wireless paths are dynamically steered and reconfigured, then resource utilization improves, but network stability deteriorates
Solution Approach 1:
The patent implements dynamic steering of traffic flows between wireless paths based on real-time network conditions, client device movements, and traffic characteristics. The system continuously monitors and adapts the grouping of traffic flows, reconfiguring wireless paths as needed to optimize resource utilization. This dynamic approach allows the network to respond to changing conditions while maintaining overall stability through controlled reconfiguration.

AI summary
Devices, computer-program products, and methods for identifying two or more traffic flows with similar packet traffic characteristics are disclosed. In some implementations, the traffic flows may be transmittable over one or more wireless paths. In these implementations, the method may further include identifying a wireless path along which the two or more traffic flows may be transmitted. In some implementations, the method may further include determining whether the wireless path can implement spatial signal multiplexing. Making this determination may include using sounding information associated with the wireless path. In some implementations, the method may include grouping two or more traffic flows to transmit along the wireless path when the wireless path implements spatial signal multiplexing. In these implementations, the two or more traffic flows may be grouped according to similar packet traffic characteristics. Grouping the two or more traffic flows may allow spatial signal multiplexing on the wireless path.
