WLAN Trigger Frame Aggregation for Multi-Event Sensing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WLAN sensing mechanisms lack an efficient method to aggregate and report multiple measurement results, leading to resource overhead and inefficiencies in feedback processes.
Innovation Solution
A communication method and apparatus that utilize a trigger frame to initiate a measurement report frame containing multiple measurement results, including channel state information (CSI), optimizing resource usage by enabling delayed feedback operations.

Engineering Contradiction Analysis
1Loss of time
If multiple measurement results are reported separately in individual frames, then each measurement result can be及时反馈 (timely feedback), but resource overhead increases due to multiple separate transmissions
Solution Approach 1:
The patent combines multiple measurement results into a single measurement report frame. The trigger frame includes a measurement token field that can indicate multiple measurement instances, and the responder aggregates these results in one report frame rather than sending separate frames for each measurement, thereby reducing the number of transmissions and resource overhead while maintaining timely feedback through the token-based triggering mechanism
Solution Approach 2:
The patent uses a trigger frame with a measurement token field that is prepared in advance to indicate multiple measurement instances. This preliminary indication allows the responder to pre-prepare an aggregated report containing multiple measurement results, enabling efficient batch reporting that reduces subsequent transmission overhead while ensuring timely delivery of all measurement data
