Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a UE generates RF map information independently in a new environment, then the UE can eventually obtain accurate RF map data, but the process takes too much time and causes delayed optimization of wireless connections

Engineering Contradiction:

ImproveRF map accuracyVSAvoidtime for RF map generation

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The network node pre-generates RF map information based on historical data and environmental characteristics before the UE arrives or before the UE needs to operate in that environment. When the UE enters the new environment, it receives the pre-generated RF map information immediately, avoiding the time-consuming process of independent RF map generation while still obtaining accurate data.

Inventive Principle:

Principle #10Preliminary action

2Loss of time

If the network provides pre-generated RF map information to UEs, then UEs can quickly optimize wireless connections, but the RF map information may not be accurate enough for specific UE scenarios

Engineering Contradiction:

Improvetime for connection optimizationVSAvoidRF map accuracy for specific UE

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The system implements a feedback mechanism where the pre-generated RF map information is provided to the UE, and the UE's measurement results and connection performance are fed back to the network node. The network node uses this feedback to refine and update the RF map information, progressively improving its accuracy for specific UE scenarios while maintaining quick provision of initial RF map data.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If multiple UEs independently generate RF map information, then each UE can have customized RF map data, but the overall system efficiency decreases and connection issues increase

Engineering Contradiction:

Improvecustomized RF map accuracyVSAvoidsystem efficiency for RF map generation

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The network node merges RF map information from multiple UEs by collecting measurement data and environmental observations from different UEs in the same or overlapping environments. The network node aggregates this information to create a comprehensive, accurate RF map that reflects the collective experience of multiple UEs, then provides this merged information to all UEs, improving both accuracy and system efficiency.

Inventive Principle:
