Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single measurement gap pattern is configured, then device complexity is reduced, but measurement precision and handover decision accuracy deteriorate due to inability to perform concurrent measurements across multiple frequency ranges
Solution Approach 1:
The patent divides the measurement process into multiple independent gap patterns, each dedicated to specific frequency ranges or cells. This segmentation allows the UE to perform measurements on different frequencies simultaneously without interference, improving measurement precision while keeping each individual gap pattern simple and manageable.
Solution Approach 2:
The patent introduces a time dimension by configuring multiple measurement gap patterns that operate in parallel across different time resources. This enables concurrent measurements on multiple frequency ranges by utilizing different time slots, thereby improving measurement accuracy without increasing device complexity.
2Productivity
If multiple measurement gap patterns are configured in parallel, then productivity of signal quality measurements increases, but device complexity increases due to multiple concurrent measurement configurations
Solution Approach 1:
By segmenting measurements into distinct gap patterns with specific associations to frequency ranges or cells, the system enables parallel measurement operations. Each segmented gap pattern can be independently configured and managed, increasing overall measurement throughput while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent creates universal measurement gap patterns that can be applied across multiple frequency ranges and cell types. This multi-functionality allows a single gap pattern design to serve multiple purposes, increasing measurement productivity without proportionally increasing device complexity.
3Measurement precision
If measurement gaps are configured for each frequency range separately, then measurement precision improves, but loss of time increases due to sequential measurement execution
Solution Approach 1:
The patent transitions from sequential time-based measurements to parallel time-frequency measurements by configuring multiple gap patterns that operate simultaneously on different frequency ranges. This dimensional change allows precise measurements on multiple frequencies without the time penalty of sequential execution, reducing handover decision delays.
Solution Approach 2:
The system performs preliminary configuration of multiple measurement gap patterns in advance, establishing all necessary measurement resources before handover decisions are needed. This preliminary setup enables immediate concurrent measurements when required, improving both measurement precision and reducing time loss.

AI summary
User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for performing multiple signal quality measurements in a 5G network, the processing circuitry is to encode configuration signaling for transmission to a base station. The configuration signaling indicates the UE supports multiple measurement gap (MG) patterns in parallel. RRC signaling responsive to the configuration signaling is decoded. The RRC signaling comprising configuration information to configure the UE for multiple measurement gaps in parallel and provides SMTC for synchronization signal transmissions within the multiple measurement gaps. A plurality of SSBs is decoded using periodicity and duration information of the synchronization signal transmissions included in the SMTC, the plurality of SSBs received during the multiple measurement gaps. Multiple signal quality measurements are encoded for transmission to the base station, the multiple signal quality measurements based on the plurality of SSBs.
