Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If WTRUs perform sensing measurements continuously without time window constraints, then measurement accuracy improves, but energy consumption and processing complexity increase

Engineering Contradiction:

Improvesensing measurement accuracyVSAvoidWTRU energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic sensing measurements within configured time windows rather than continuous measurements. The network configures specific time windows during which WTRUs perform sensing measurements on downlink reference signals, allowing measurements to be periodic and event-driven rather than continuous, thus reducing energy consumption while maintaining measurement accuracy when needed

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The network pre-configures time windows and trigger conditions before WTRUs perform measurements. By establishing measurement configurations in advance including time window parameters and reporting triggers, the system avoids unnecessary measurements and reduces energy consumption while ensuring measurements are performed when relevant

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If WTRUs report all sensing measurements frequently, then network awareness of sensing data improves, but signaling overhead and network processing load increase

Engineering Contradiction:

Improvesensing data completenessVSAvoidreporting system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent implements feedback-based reporting where WTRUs compare current sensing measurements against previously reported measurements and only report when trigger conditions are satisfied. This feedback mechanism ensures the network receives relevant sensing data updates without excessive signaling, as reporting is driven by actual changes in the sensed environment rather than fixed periodicity

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system extracts and reports only the relevant sensing measurements that satisfy trigger conditions rather than reporting all measurements. By filtering measurements based on configured criteria such as threshold comparisons or changes from previous reports, the system reduces signaling overhead while maintaining network awareness of important sensing data

Inventive Principle:

Principle #2Taking out (Extraction)

3Area of stationary object

If WTRUs perform measurements across extended measurement ranges, then detection coverage improves, but measurement processing time and computational load increase

Engineering Contradiction:

Improvemeasurement coverage areaVSAvoidmeasurement processing time

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

The patent segments the measurement process into discrete time windows with specific measurement ranges configured by the network. Instead of performing measurements continuously across all possible ranges, the system divides measurements into segmented time intervals with focused measurement ranges, reducing processing time while maintaining comprehensive coverage over time through the sequence of time windows

Inventive Principle:

Principle #1Segmentation

AI summary

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are provided for object detection over a wireless network. A method performed by a wireless transmit/receive unit (WTRU) includes receiving, from a wireless network, a configuration that includes time windows during which the WTRU performs sensing measurements based on the periodic downlink reference signals, where each time window includes a measurement range, and a trigger condition associated with reporting the sensing measurements to the wireless network. The method also includes receiving periodic downlink reference signals. The method also includes performing sensing measurements during at least a present time window and a prior time window of the time windows, comparing sensing measurements of the measurement range of the present time window to sensing measurements of the measurement range of the prior time window, and in response to the comparison satisfying the trigger condition, reporting the sensing measurements to a wireless network.
