Multi-Link WLAN Access Control for MLA Transmission Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems where terminals using multi-link aggregation (MLA) and non-MLA coexist, MLA transmission opportunities are often hindered by non-MLA terminals initiating transmissions first, leading to channel occupancy and disabling MLA transmission.
Innovation Solution
Implementing a mechanism where an access point (AP) sets a multi-link aggregation period (MLA period) and sends notification elements to prioritize MLA transmission, while also setting non-MLA transmission parameters to avoid conflicts, using enhanced distributed channel access (EDCA) parameters for both.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless communication terminals are connected in a wireless mesh network to extend coverage area, then coverage area is improved, but power consumption increases due to mesh routing protocols and signal forwarding operations
Solution Approach 1:
The gateway terminal automatically determines whether to forward packets based on destination address matching, eliminating the need for complex mesh routing protocol processing. This self-service approach reduces power consumption while maintaining extended coverage capabilities.
Solution Approach 2:
The patent extracts and removes complex mesh routing protocol processing from gateway terminals, keeping only simple destination address matching. This extraction reduces the computational burden and power consumption while preserving the coverage extension benefit.
2Adaptability or versatility
If packet forwarding is performed at gateway terminals in a mesh network, then network coverage and connectivity are improved, but processing load and power consumption increase
Solution Approach 1:
The patent extracts complex routing decision-making from gateway terminals and centralizes it in the access point. Gateway terminals only perform simple destination address matching, dramatically reducing their processing load while maintaining network connectivity.
Solution Approach 2:
The access point acts as an intermediary that handles complex routing decisions. Gateway terminals delegate forwarding decisions to the access point, reducing their processing complexity while maintaining network adaptability.
3Adaptability or versatility
If conventional mesh routing protocols are used for packet forwarding, then routing capability is improved, but processing time and power consumption increase
Solution Approach 1:
The patent extracts complex routing protocol processing from gateway terminals and performs it centrally at the access point. This extraction significantly reduces processing time at gateway terminals while maintaining routing capability through destination address matching.
Solution Approach 2:
The access point pre-determines forwarding decisions based on destination addresses. This preliminary action at the access point eliminates the need for time-consuming routing protocol processing at gateway terminals during actual packet forwarding.
