Multi-Link WLAN Sensing Management Frames for Complete Interactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless local area network (WLAN) sensing technologies face inefficiencies and complexity in multi-link devices due to the lack of explicit specifications for transmitting sensing-related management frames over different links, leading to incomplete frame interaction sequences and reduced efficiency in WLAN sensing operations.
Innovation Solution
A method and apparatus for multi-link devices that restrict the transmission of specified management frames related to sensing, such as sensing measurement report frames and sensing by proxy report frames, to a single designated link, while allowing other management frames to be transmitted over multiple links, ensuring complete frame interaction sequences and simultaneous execution of sensing measurements across different links.

Engineering Contradiction Analysis
1Productivity
If sensing management frames are transmitted over multiple links in multi-link devices, then link utilization and throughput are improved, but frame interaction sequence completeness deteriorates and sensing operation reliability is reduced
Solution Approach 1:
The patent segments management frames into two categories: sensing management frames (which maintain link-specific transmission) and other management frames (which can be transmitted over multiple links). This segmentation allows different types of frames to have different transmission behaviors, ensuring that sensing frame interaction sequences remain complete and reliable while other frames can utilize multiple links for improved throughput.
Solution Approach 2:
The patent applies local quality by making the transmission behavior of management frames link-specific for sensing frames. Each link maintains its own sensing management frame transmission characteristics, ensuring that the frame interaction sequences for sensing operations remain complete and reliable on each individual link, while other management frames can be transmitted more flexibly across multiple links.
2Reliability
If sensing management frames are restricted to a single link, then frame interaction sequence completeness is improved, but multi-link sensing operation capability deteriorates
Solution Approach 1:
The patent segments management frames into sensing-specific frames and other management frames, allowing sensing frames to maintain link-specific transmission for reliability while other frames can utilize multi-link transmission for enhanced capability. This segmentation enables the system to achieve both complete frame interaction sequences and versatile multi-link sensing operations.
Solution Approach 2:
The patent implements multi-functionality by allowing different types of management frames to have different transmission behaviors. Sensing management frames follow link-specific transmission rules to ensure reliability, while other management frames can be transmitted over multiple links to enhance overall system capability and versatility.
3Productivity
If all management frames are transmitted over multiple links, then throughput is improved, but sensing operation precision and reliability deteriorate due to incomplete frame interactions
Solution Approach 1:
The patent segments management frames into sensing frames and other frames, ensuring that sensing frames maintain link-specific transmission to preserve measurement precision and reliability. Other management frames can be transmitted over multiple links to improve throughput, thus resolving the contradiction between productivity and measurement precision.
