Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional network planning and configuration methods are used for sidelink devices and smart repeaters, then network control and management are maintained, but device complexity and configuration difficulty increase
Solution Approach 1:
The patent enables sidelink devices and smart repeaters to perform autonomous discovery and configuration through self-service mechanisms. Devices automatically transmit discovery sequences and process reply sequences without manual intervention, while smart repeaters self-configure by processing configuration information embedded in sidelink control information, eliminating the need for complex network planning procedures
Solution Approach 2:
The patent implements preliminary action by pre-defining discovery sequence structures, reply sequence formats, and configuration information encoding schemes. These preliminary protocols enable devices to automatically perform discovery and configuration operations without requiring complex real-time decision-making or manual network planning
2Adaptability or versatility
If sidelink discovery and configuration procedures are simplified, then device deployment flexibility improves, but network planning control may be reduced
Solution Approach 1:
The patent applies dynamics by enabling flexible adaptation of discovery and configuration procedures based on operational conditions. The system dynamically adjusts beam conformance parameters and repeater configuration based on real-time channel conditions and service requirements, allowing deployment flexibility without sacrificing network control
Solution Approach 2:
The patent utilizes parameter changes by modifying beam conformance parameters, discovery sequence timing, and repeater configuration parameters based on operational requirements. These parameter adjustments enable flexible deployment scenarios while maintaining network planning control through standardized parameter management
3Reliability
If beam conformance procedures are established through discovery sequences, then communication reliability improves, but time delay in establishing connections increases
Solution Approach 1:
The patent implements periodic action through structured discovery sequences transmitted at defined intervals and periods. The discovery process uses periodic transmission of discovery sequences and reply sequences with predetermined timing relationships, ensuring reliable beam conformance establishment while minimizing discovery time through optimized periodic patterns
Solution Approach 2:
The patent applies preliminary action by pre-configuring beam conformance parameters and discovery sequence timing before actual communication begins. This preliminary setup enables rapid connection establishment while maintaining high reliability, as the beam alignment parameters are prepared in advance based on predicted channel conditions
