Wireless Device Scheduling Access Point Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Increasing the number of wireless access points to achieve frequency reuse in wireless communication networks is costly and can lead to synchronization issues between access points, resulting in data transmission errors due to non-synchronized communication sub-frames.
Innovation Solution
A wireless device receives data transmission scheduling information from a scheduling access point and generates a data transmission request, which it transmits to a transmission access point, allowing the scheduling access point to adjust scheduling based on neighboring access points and device feedback, thereby avoiding direct wired connections and reducing synchronization errors.

1Productivity
If additional wireless access points are deployed to increase frequency reuse and coverage area, then data transmission capacity is improved, but system cost and complexity increase
Solution Approach 1:
The patent introduces a scheduling access point as an intermediary that coordinates data transmissions between multiple transmission access points and wireless devices. The scheduling access point receives data transmission requests from wireless devices, determines optimal transmission timing based on scheduling information from multiple access points, and manages the transmission process. This intermediary role eliminates the need for direct wired connections between all access points while maintaining coordinated operation, thereby reducing system complexity and cost.
2Productivity
If multiple access points are deployed to achieve frequency reuse, then data transmission efficiency is improved, but synchronization errors increase due to non-synchronized communication sub-frames
Solution Approach 1:
The patent implements a feedback mechanism where wireless devices transmit data transmission requests to the scheduling access point, which then adjusts scheduling information based on feedback from multiple access points. The scheduling access point receives scheduling information from multiple access points, determines optimal transmission timing, and coordinates data transmissions to avoid interference. This feedback loop ensures that communication sub-frames are properly synchronized across multiple access points, preventing data transmission errors while maintaining high data transmission efficiency.
