Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing based on 3GPP signals is implemented, then communication capabilities in 5G networks are enhanced, but device complexity increases due to the need for registration procedures and sensing group setup
Solution Approach 1:
The patent enables user equipment to perform both communication and sensing functions using the same 3GPP signal infrastructure. The sensing group setup procedure allows UEs to participate in sensing measurements while maintaining their communication capabilities, making the system multi-functional without requiring separate dedicated sensing hardware or protocols.
Solution Approach 2:
The network introduces intermediary signaling elements such as sensing group setup request messages, response messages, and completion messages to coordinate sensing activities. These intermediary messages manage the complexity by providing structured interaction protocols between UEs and the network, rather than requiring direct peer-to-peer sensing coordination.
2Reliability
If sensing group setup procedures are implemented, then sensing functionality is enabled, but signaling overhead increases due to registration and message exchanges
Solution Approach 1:
The patent combines sensing group setup procedures with existing registration procedures. The sensing group setup request and response messages are integrated into the existing signaling framework, allowing sensing functionality to be established without requiring completely separate signaling channels or procedures.
Solution Approach 2:
The network configures a minimum number of responders required for successful sensing group setup. This partial action approach allows the system to proceed with sensing functionality even if not all potential responders are available, reducing the signaling overhead required to achieve full sensing capability while maintaining reliability.
3Reliability
If minimum number of responders threshold is enforced, then sensing measurement reliability is improved, but setup time increases due to additional verification steps
Solution Approach 1:
The network pre-configures the minimum number of responders threshold before initiating sensing group setup. This preliminary configuration allows UEs to understand the requirements in advance and prepare accordingly, reducing the time required during actual setup while ensuring reliability standards are met.
Solution Approach 2:
The sensing group setup response message includes feedback information about the number of available responders. This feedback mechanism allows the initiating UE to make informed decisions about whether to proceed with setup, potentially avoiding unnecessary delays when the minimum threshold cannot be met while ensuring reliability when it can be satisfied.

AI summary
Provided in one embodiment of the present disclosure is a method by which a first device performs communication. The method may comprise steps in which: a UE performs a registration procedure for registering in an AMF node; a sensing group setup request message for setting up a sensing group is transmitted to one or more candidate responders including a second device; receiving a response message from the second device; and determining, on the basis of the number of minimum responders of the sensing group, whether to transmit a completion message.
