Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing capability information is exchanged using traditional signaling messages, then sensing measurement setups can be established, but unnecessary signaling messages are generated and communication resources are wasted
Solution Approach 1:
The patent merges the sensing capability information exchange with the existing beacon frame transmission mechanism. The AP includes the numeric count of supported MSs in the beacon frame's capability information field, combining multiple functions (network announcement + sensing capability indication) into a single communication structure, thereby eliminating separate signaling messages for capability exchange
Solution Approach 2:
The beacon frame is given multi-functionality: it simultaneously serves as the network announcement message and as the sensing capability information carrier. By making the beacon frame universal, the patent eliminates the need for dedicated sensing capability signaling messages, reducing communication overhead and resource consumption
2Productivity
If dynamic adjustment of sensing capability information is implemented, then communication efficiency is improved, but complexity of capability management increases
Solution Approach 1:
The patent implements dynamic adjustment by allowing the AP to update the numeric count of supported MSs in the beacon frame according to current system state. When MSs are established or released, the AP modifies the capability information field in subsequent beacon frames, enabling real-time reflection of sensing capabilities without complex negotiation protocols
Solution Approach 2:
The system uses feedback mechanisms where stations read the numeric count from beacon frames and adjust their MS establishment requests accordingly. This feedback loop allows stations to adapt their behavior based on current AP capabilities, simplifying the overall management complexity through distributed intelligence
3Ease of manufacture
If sensing measurement setups are established without capability indication, then setup establishment is simplified, but interference with other communication capabilities occurs
Solution Approach 1:
The patent applies preliminary action by having the AP announce its sensing capability (numeric count of supported MSs) in advance within the beacon frame before stations attempt to establish MSs. This advance capability indication allows stations to prepare appropriate requests and avoid attempting to establish MSs that exceed AP capabilities, preventing interference and resource waste

AI summary
A communication method performed by an AP includes: determining a first radio frame, in which the first radio frame includes first identification information; the first identification information indicates a first numeric count of sensing measurement setups (MSs) supported by an AP to establish at the first moment; the first identification information indicates a second numeric count of MSs supported by an AP to establish at the second moment; and the first numeric count is different from the second numeric count; and sending the first radio frame.
