Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If frequency hopping is performed in LTE systems, then communication reliability is improved through diversity, but the system cannot adapt to flexible transmission requirements of 5G systems
Solution Approach 1:
The patent implements dynamic frequency hopping control by enabling the network device to configure whether frequency hopping should be performed based on current communication scenarios. The network device determines parameters such as time interval thresholds, basic parameter sets, and slot configurations to dynamically control the terminal's frequency hopping behavior, allowing the system to adapt between fixed and flexible transmission modes as needed.
Solution Approach 2:
The patent changes key parameters including time interval thresholds, subcarrier spacing, symbol length, and slot configurations to control frequency hopping behavior. By adjusting these parameters based on communication conditions, the system can transition between different transmission modes (fixed frequency hopping vs. flexible transmission) to balance reliability and adaptability.
2Adaptability or versatility
If frequency hopping is dynamically controlled based on communication scenarios, then adaptability to 5G flexible transmission is improved, but system complexity increases due to additional control parameters
Solution Approach 1:
The patent makes the network device perform multiple functions by having it determine various control parameters (time interval thresholds, basic parameter sets, slot configurations) and send corresponding first information to control frequency hopping. This multi-functional approach consolidates control logic in the network device, reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The patent implements a feedback mechanism where the network device sends first information based on determined parameters to instruct the terminal on frequency hopping behavior. This closed-loop control allows the system to adapt to changing conditions while maintaining manageable complexity through structured information flow between network and terminal.
3Productivity
If the network device sends first information to instruct frequency hopping, then communication efficiency is improved through adaptive transmission, but information transmission overhead increases
Solution Approach 1:
The patent applies partial action by having the network device send first information only when necessary based on determined parameters. The control mechanism selectively enables frequency hopping instructions rather than continuously transmitting information, reducing overhead while maintaining efficiency where needed.
Solution Approach 2:
The patent implements preliminary action by having the network device determine control parameters and prepare first information in advance based on communication scenarios. This allows efficient adaptive transmission without requiring continuous real-time information exchange, reducing overhead by performing control decisions beforehand.
