UWB Sensing Request Routing With Initiator Address Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UWB sensing technologies lack effective definitions for sensing measurement-related reports and require improvements in sensing request and control information design.
Innovation Solution
A sensing communication method that includes receiving and processing sensing requests with initiator address information, forwarding or parsing based on address matching, and transmitting ACK frames or data frames to ensure accurate communication, along with configuring frame structures using sensing packet bitmaps for flexibility.
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 receiver the sensing request is sent
Solution Approach 1:
The patent segments the address information by separating the destination address (in MAC header) from the sensing initiator address (in MAC payload). This allows the broadcast destination address to reach multiple receivers while the sensing initiator address in the payload identifies the specific intended receiver, resolving the contradiction between multi-receiver capability and receiver identification.
2Adaptability or versatility
If the sensing request is forwarded through relay nodes, then the sensing initiator address can be reached, but the communication apparatus cannot determine whether it is the relay node or the sensing initiator
Solution Approach 1:
The patent implements self-service by having each communication apparatus independently determine its own role (relay node or sensing initiator) by comparing its own address with the sensing initiator address extracted from the MAC payload. This self-determination mechanism eliminates the need for complex external identity verification systems.
3Loss of information
If the MAC payload includes sensing initiator address information, then the communication apparatus can effectively identify the receiver, but the MAC header structure becomes more complex
Solution Approach 1:
The patent makes the MAC payload multi-functional by using it to carry both sensing measurement-related information and the sensing initiator address. This universal usage of the payload field allows receiver identification without adding separate dedicated fields, thereby minimizing structural complexity while maintaining identification accuracy.

AI summary
A sensing communication method and an apparatus are provided, and may be applied to a WPAN system or a 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. 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.
