Multi-Link TDLS Setup Through Unified Frame Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing multiple Tunneled Direct Link Setup (TDLS) links between non-access point multi-link devices (MLDs) is complicated and inefficient, leading to restricted wireless device performance.
Innovation Solution
A device configured to transmit a TDLS setup request frame announcing multiple proposed links, receive a response frame indicating selected links, and establish those links via a confirm frame, using a single sequence of frames over one link and one station from each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple TDLS links are established by exchanging frames on each link separately, then multiple direct communication paths are created, but the setup process becomes complicated and inefficient
Solution Approach 1:
The patent combines multiple TDLS link establishment processes into a single unified setup procedure. Instead of exchanging frames separately on each link, the method uses one TDLS setup request frame, one response frame, and one confirm frame to establish multiple TDLS links simultaneously, thereby reducing procedural complexity while maintaining multi-link capability
Solution Approach 2:
The patent makes the TDLS setup frames multi-functional by enabling them to carry information for multiple link establishments. The setup request frame announces multiple proposed TDLS links, the response frame indicates multiple selected links, and the confirm frame establishes all selected links, allowing a single frame exchange sequence to perform multiple link setup functions
2Productivity
If multiple TDLS links are established by exchanging frames on each link, then direct communication paths are created, but traffic congestion and performance restrictions occur
Solution Approach 1:
The patent merges multiple frame exchange sequences into a single consolidated setup process. By establishing multiple TDLS links through one request-response-confirm frame sequence rather than separate exchanges per link, the method reduces overall traffic volume and minimizes congestion during the setup phase, thereby improving wireless device performance
