5G-Wi-Fi MAP Coordination Using rTWT to Reduce Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex mobile communication networks, there is a challenge of co-channel interference between 5G and Wi-Fi services due to the lack of coordinated channel allocation, leading to sub-optimal network performance, especially in high-demand environments.
Innovation Solution
A Multi-Access Point Coordination (MAPc) processor schedules restricted Target Wake Time (rTWT) service intervals for both 5G and Wi-Fi access points based on traffic flow properties, using a near-synchronized Buffer Status Report (BSR) trigger mechanism to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 5G and Wi-Fi services operate independently without coordination, then each service can operate autonomously, but co-channel interference occurs leading to sub-optimal network performance
Solution Approach 1:
The patent introduces a coordination mechanism as an intermediary between 5G and Wi-Fi access points. This mediator coordinates channel allocation and scheduling decisions, preventing co-channel interference while maintaining autonomous operation of individual services. The coordination entity manages resource allocation across both networks without requiring direct integration of the 5G and Wi-Fi systems themselves.
2Device complexity
If rTWT service intervals are scheduled without coordination between Wi-Fi and 5G access points, then scheduling is simple, but interference increases reducing network efficiency
Solution Approach 1:
The patent merges the scheduling functions of Wi-Fi and 5G access points into a unified coordination mechanism. The coordinated rTWT scheduling combines resource allocation decisions from both networks, ensuring that service intervals are assigned in a way that minimizes interference while maintaining overall network efficiency. This unified approach balances complexity reduction with performance optimization.

AI summary
A Fifth Generation (5G) and Wi-Fi Multi-Access Point Coordination (MAPc) function may be provided. A MAPc processor may determine a first traffic flow and a second traffic flow for a User Equipment (UE) and a property of the first traffic flow and of the second traffic flow. The MAPc processor may schedule restricted Target Wake Time (rTWT) service intervals on a Wi-Fi AP for the first traffic flow, and the MAPc processor may schedule rTWT service intervals on a 5G AP for the second traffic flow. The rTWT service intervals on the Wi-Fi AP may be at different times than the rTWT service intervals on the 5G AP.
