Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate termination frames are sent to each sensing responder individually, then each responder receives its termination frame reliably, but the number of transmission operations increases and spectral efficiency deteriorates
Solution Approach 1:
The patent combines multiple individual termination frames into a single multi-user PPDU structure that can be transmitted simultaneously to multiple sensing responders. This merging approach reduces the number of transmission operations while maintaining reliable delivery to each responder through individual address fields and QoS information elements within the unified frame structure.
Solution Approach 2:
The multi-user PPDU structure serves multiple functions simultaneously: it acts as a termination frame for multiple sensing responders, provides individual address identification for each responder, includes QoS information elements for each user, and enables simultaneous transmission to multiple devices. This multi-functionality resolves the contradiction by achieving both reliable individual delivery and improved spectral efficiency.
2Ease of operation
If multiple termination frames are transmitted separately, then each frame can be processed individually, but the transmission time increases and network resource occupation increases
Solution Approach 1:
Multiple termination frames are merged into a single multi-user PPDU transmission, reducing the total transmission time and network resource occupation. The individual processing capability is maintained through separate address fields and QoS information elements that allow each responder to identify and process its own termination frame independently within the unified structure.
3Device complexity
If individual termination frames are used for each sensing responder, then the protocol structure remains simple, but the number of frames increases and network resource occupation increases
Solution Approach 1:
The patent merges multiple termination frames into a single multi-user PPDU, reducing the quantity of frames from multiple separate transmissions to one unified transmission. The protocol structure complexity is managed through standardized fields including individual address identification and QoS information elements for each user, which follow established Wi-Fi protocol conventions.
