Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensing measurements are performed continuously using network resources, then sensing accuracy and object detection capability are improved, but communication service quality deteriorates due to resource contention
Solution Approach 1:
The patent implements dynamic sensing configuration where the WTRU adapts its sensing measurement behavior based on detected events. The sensing configuration is not static but changes dynamically - the WTRU performs sensing measurements at different rates and with different configurations depending on whether events are detected, allowing the system to optimize between sensing accuracy and communication service quality in real-time
Solution Approach 2:
The patent employs periodic sensing measurements at predetermined measurement occasions rather than continuous measurements. The WTRU is configured to perform sensing measurements at specific intervals and occasions, which reduces overall network resource consumption while maintaining adequate sensing capability. This periodic approach allows communication services to utilize network resources during non-measurement periods
2Productivity
If multiple sensing configurations are applied to different measurements, then network resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the sensing measurement process into multiple distinct configurations, each optimized for specific sensing scenarios. Different sensing configurations are defined with different parameters (e.g., measurement bandwidth, filtering coefficients, reporting thresholds) that can be selectively applied. This segmentation allows the WTRU to use simpler configurations for routine measurements and more complex configurations only when needed, improving overall resource efficiency while managing complexity through structured organization
Solution Approach 2:
The patent utilizes parameter changes to switch between different sensing configurations. The WTRU can adjust sensing measurement parameters such as bandwidth, filtering, and reporting based on the current configuration indication received from the network. This allows flexible adaptation to different sensing requirements without requiring completely different measurement mechanisms, thereby improving resource allocation efficiency while keeping the underlying device complexity manageable through parameter-based control

AI summary
Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for dynamic sensing configuration of a wireless network node (e.g., a Wireless Transmit/Receive Unit). Dynamic sensing configuration may be sent via a downlink control channel (e.g., DCI). The sensing configuration may specify expected characteristics of a reflection of a reference signal from a target object. A WTRU may be controlled to perform a sequence of dynamically configured sensing measurements in which different sensing configurations are applied to different measurements to manage the allocation of its resource to the sequence of measurements. A sequence of measurements may be triggered in response to the detection of an event (e.g. an object detection event) by the WTRU. The WTRU is thus controlled to perform a sequence of measurements of reflections from the object during a relevant time period thereby efficiently allocating the resources of a wireless network for sensing.
