Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If WLAN sensing measurement process is implemented using current Wi-Fi technologies, then sensing measurement capability is provided, but efficiency and accuracy in indicating NDP receipt are insufficient
Solution Approach 1:
The patent introduces a wireless frame as an intermediary carrier that transports indication information between the access point and terminal. This frame includes a specific indication field that clearly signals whether the terminal has received the NDP, resolving the ambiguity in current technologies and improving both measurement accuracy and efficiency
2Reliability
If indication information is not explicitly transmitted, then communication overhead is reduced, but sensing measurement reliability deteriorates
Solution Approach 1:
The patent merges the indication information with the existing wireless communication framework by incorporating it into the data frame structure. The indication field is integrated into the normal data exchange process, allowing reliable sensing measurement indication without requiring a separate complex protocol mechanism
Data Source
AI summary
A communication method includes: determining a wireless frame, wherein the wireless frame comprises first indication, and the first indication indicates a wireless local area network (WLAN) sensing measurement process corresponding to the wireless frame; and sending the wireless frame to a sensing responder to instruct the sensing responder to receive a null data packet (NDP).
