Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing operations are performed in wireless communication systems, then sensing capabilities are improved, but interference with communication operations occurs
Solution Approach 1:
The system segments time resources by dividing them into communication time periods and sensing time periods. The sensing node performs sensing operations only in designated sensing time periods when the communication node is not transmitting or receiving signals, thereby eliminating interference while maintaining both communication and sensing capabilities.
Solution Approach 2:
The system dynamically adjusts the scheduling of sensing and communication operations based on real-time conditions. The network entity coordinates the timing of sensing operations with communication operations, allowing the system to adaptively allocate resources and avoid interference while maximizing the utilization of sensing and communication capabilities.
2Productivity
If sensing operations are coordinated with communication operations, then resource usage efficiency is improved, but system complexity increases
Solution Approach 1:
The network entity serves as an intermediary that coordinates between the communication node and sensing node. It receives sensing capability information from the sensing node, determines appropriate sensing time periods that do not conflict with communication operations, and provides sensing configuration information to the sensing node, thereby simplifying the coordination process while improving resource efficiency.
Solution Approach 2:
The system design allows the same wireless infrastructure to serve dual purposes: communication operations and sensing operations. By enabling the network entity to manage both types of operations and by allowing time-division multiplexing, the system achieves multi-functionality without requiring separate dedicated systems, thus improving resource usage efficiency while keeping complexity manageable.

AI summary
Disclosed are techniques for wireless sensing. In some aspects, a sensing node may receive, from a sensing server, a first indication that the sensing node is permitted to perform one or more sensing operations in a first time period within a first coverage area based on a determination that the one or more sensing operations do not interfere with one or more communication operations performed by a joint sensing and communication (JCS) node, the one or more communication operations including a downlink communication operation in a second time period and an uplink communication operation in a third time period. The sensing node may perform, based on the first indication, the one or more sensing operations on an object to obtain a sensing result.
