Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If capability indication information is transmitted to indicate terminal support for NR and E-UTRAN frequency layer measurements, then network configuration accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent combines capability indication for NR frequency layer measurements and E-UTRAN frequency layer measurements into a unified capability indication information structure. This merging reduces the number of separate signaling messages required while maintaining comprehensive capability information, thereby reducing signaling overhead without sacrificing indication accuracy.
Solution Approach 2:
The capability indication information is designed to serve multiple functions simultaneously: it indicates support for NR frequency layer measurements, E-UTRAN frequency layer measurements, and the combination thereof. This multi-functionality eliminates the need for separate indication mechanisms for each measurement type, reducing overall signaling overhead while maintaining precise capability indication.
2Reliability
If multiple capability indication information are transmitted for different frequency layers, then configuration reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments capability indication into distinct components for NR frequency layer measurements and E-UTRAN frequency layer measurements within a unified information structure. This segmentation allows the network device to process each capability type independently while maintaining overall configuration reliability, reducing processing complexity compared to handling multiple separate indication messages.
Solution Approach 2:
The capability indication information provides feedback to the network device about terminal measurement capabilities, enabling the network to make informed configuration decisions. This feedback mechanism ensures reliable configuration by matching network decisions with actual terminal capabilities, while the structured format keeps processing complexity manageable through standardized information exchange.
