Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MAC header carries a destination address field with broadcast address, then multiple receivers can receive the sensing request, but the communication apparatus cannot effectively identify to which the sensing request is sent
Solution Approach 1:
The patent introduces a sensing initiator address field in the MAC payload as an intermediary element that carries the actual destination address information. This field acts as a mediator between the broadcast mechanism (which enables multiple receivers) and the need for specific destination identification. The sensing initiator address field resolves the contradiction by providing explicit address information to relay nodes and sensing initiators while maintaining broadcast capability for general delivery.
2Productivity
If the communication apparatus forwards the sensing request without address matching, then the sensing request can reach the sensing initiator through relay nodes, but the relay node cannot effectively identify the receiver
Solution Approach 1:
The patent applies preliminary action by pre-configuring the sensing initiator address field in the MAC payload before the sensing request is transmitted through relay nodes. This field is prepared in advance with the correct sensing initiator address, enabling relay nodes to perform address matching and identification without losing receiver information during the forwarding process. The preliminary configuration ensures that destination identification capability is maintained throughout the multi-hop transmission.
3Measurement precision
If the MAC payload includes sensing initiator address information, then the communication apparatus can identify the receiver, but the MAC header structure becomes more complex
Solution Approach 1:
The patent segments the address information functionality by separating the destination address field (in MAC header) from the sensing initiator address field (in MAC payload). This segmentation allows the MAC header to maintain its standard structure for general frame delivery, while the MAC payload contains the specific sensing initiator address information needed for precise address matching. The segmentation resolves the contradiction by distributing address-related functions across different layers without overcomplicating the MAC header structure.

AI summary
A sensing communication method and an apparatus are provided, and may be applied to a WPAN system or a sensing (sensing) system that supports UWB, for example, a wireless local area network system that supports a 802.15.4a protocol, a 802.15.4z protocol, a 802.15.4ab protocol, or the like in 802.15 series protocols, or supports 802.11 series protocols such as a next-generation Wi-Fi protocol of the IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and a next-generation protocol of the 802.11be like Wi-Fi 8, UHR, or Wi-Fi AI. The method includes: A sensing requester sends a sensing request, where a MAC payload of the sensing request includes sensing initiator address information; and a communication apparatus that receives the sensing request forwards the sensing request when determining that an address of the communication apparatus does not match the sensing initiator address information; or the communication apparatus that receives the sensing request parses the sensing request when determining that the address of the communication apparatus matches the sensing initiator address information.
