Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frequency measurement and carrier aggregation configuration are performed after RRC connection establishment, then connection setup is simple, but data transmission rate and configuration speed are reduced
Solution Approach 1:
The patent applies preliminary action by performing frequency measurement and carrier aggregation configuration before the RRC connection is fully established. The terminal measures frequency and reports measurement results during the RRC setup phase, allowing the base station to pre-configure carrier aggregation parameters. This enables rapid activation of multiple carriers once the connection is established, significantly improving data transmission rate without requiring complex post-connection reconfiguration procedures.
2Reliability
If all received data is processed and validated in the PDCP layer, then data reliability is improved, but processing time and latency increase
Solution Approach 1:
The patent applies the skipping principle by implementing selective data validation in the PDCP layer. Instead of validating all received data packets, the system skips integrity verification for data marked as potentially reliable (e.g., data from established secure channels or data with valid authentication tags). This allows the terminal to rapidly process and forward data while maintaining reliability through targeted validation only where necessary, significantly reducing processing latency.
3Reliability
If comprehensive security verification is performed for all data, then data security is improved, but transmission speed decreases
Solution Approach 1:
The patent applies local quality by implementing differentiated security verification based on data characteristics and source reliability. The system performs comprehensive security checks for data from untrusted sources or critical data types, while applying reduced or skipped verification for data from trusted sources. This localized security approach maintains high security for essential data while enabling faster transmission speeds for data that can be trusted without extensive verification.
4Productivity
If configuration information is stored and reused for rapid activation, then configuration speed is improved, but signaling overhead increases
Solution Approach 1:
The patent applies the extraction principle by selectively reusing only the essential configuration information needed for rapid carrier activation, while discarding redundant signaling details. The terminal extracts and stores only critical parameters (such as frequency information, carrier identifiers, and activation timing) from previous configuration messages. During rapid activation, the terminal reuses only these extracted essential parameters, significantly reducing the amount of signaling overhead required while maintaining high configuration speed.
