Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If WLAN sensing measurement methods are implemented in bistatic and multistatic systems, then sensing measurement capability is improved, but device role identification and directionality determination become complex and unclear
Solution Approach 1:
The patent segments the device roles into distinct types (transmitter, receiver, transceiver) and uses separate identification fields in message frames to indicate each device's role. This segmentation allows clear identification of multiple devices in bistatic and multistatic systems without confusion, resolving the complexity issue while maintaining measurement precision.
Solution Approach 2:
The patent applies local quality by adding specific identification information to individual message frames sent by each device. Each device includes its own role identification (transmitter/receiver status) and directionality information in its outgoing frames, allowing other devices to locally determine roles and relationships without complex system-wide coordination.
2Productivity
If device roles and directionality information are clearly identified in message frames, then communication efficiency is improved, but message frame structure and information processing become more complex
Solution Approach 1:
The patent merges multiple pieces of information (device identification, role indication, directionality) into a single integrated message frame structure. By combining these elements in one frame rather than using separate signaling messages, the patent improves communication efficiency while the structured organization keeps processing complexity manageable.
Solution Approach 2:
The message frame structure is designed to be universal and multi-functional, serving both as a data transmission vehicle and as a role/directionality indicator. This multi-functionality eliminates the need for separate control messages, improving productivity while the standardized structure prevents excessive complexity.

AI summary
A communication method for wireless local area network (WLAN) sensing measurement includes determining, by a first device, a first message frame, and sending, by the first device, the first message frame; where the first message frame includes identification used to identify first information related to the first device, and the first information includes first identification information used to identify the first device as at least one of a receiver or a transmitter of a WLAN sensing frame.
