Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement gaps are implemented to allow signal measurements, then measurement capability is improved, but transmit latency increases due to scheduling interruptions

Engineering Contradiction:

Improvesignal measurement capabilityVSAvoidtransmit latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the measurement function from the traditional measurement gap mechanism by implementing measurement capabilities within ongoing communication sessions without requiring dedicated gap periods. This allows measurements to be performed during regular scheduling occasions, eliminating the need to remove measurement functionality while incurring latency penalties.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent maintains continuous scheduling operations during measurement activities by integrating measurements into active communication sessions. Instead of interrupting data transmission for measurements, the system performs measurements continuously during scheduled communication occasions, ensuring uninterrupted useful action while maintaining measurement capability.

Inventive Principle:

Principle #20Continuity of useful action

2Measurement precision

If measurement gaps are used to perform measurements, then measurement accuracy is improved, but scheduling efficiency deteriorates due to dropped scheduling occasions

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidscheduling efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent merges measurement operations with communication scheduling by performing measurements during active scheduling occasions rather than during separate measurement gaps. This integration allows the system to combine measurement activities with data transmission and reception, improving scheduling efficiency while maintaining measurement accuracy through proper resource allocation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic measurement configuration that adapts to current scheduling conditions. The system can dynamically adjust measurement parameters and timing based on active communication sessions, allowing measurements to be performed when resources are available without rigidly enforcing fixed measurement gaps that would reduce scheduling flexibility and efficiency.

Inventive Principle:

Principle #15Dynamics

3Productivity

If communication sessions are conducted without measurement gaps, then scheduling efficiency is improved, but interruption ratio increases negatively impacting system performance

Engineering Contradiction:

Improvescheduling efficiencyVSAvoidinterruption ratio

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms that monitor interruption ratios and system performance during communication sessions without measurement gaps. The system uses this feedback to dynamically adjust measurement configurations and scheduling parameters, ensuring that interruption ratios remain within acceptable thresholds while maintaining high scheduling efficiency throughout the communication session.

Inventive Principle:

Principle #23Feedback
