Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If OAM communication is used to achieve ultra-high speed and ultra-large bandwidth, then communication capacity is improved, but transmission reliability of target signals deteriorates
Solution Approach 1:
The patent changes the OAM mode parameter dynamically by selecting different OAM modes (e.g., OAM0, OAM1, OAM2) based on channel conditions. The network device receives indication information about channel quality and selects the most appropriate OAM mode to transmit target signals, thereby adapting the transmission parameters to maintain reliability while utilizing OAM's high capacity capabilities
Solution Approach 2:
The patent implements preliminary action by having the network device pre-select the optimal OAM mode before transmitting target signals. The network device receives indication information about channel conditions in advance, determines the best OAM mode beforehand, and then uses this pre-determined mode for transmission, ensuring reliability is maintained from the start of transmission
2Productivity
If multiple OAM modes are used to increase bandwidth, then communication efficiency is improved, but difficulty of detecting and measuring transmission quality increases
Solution Approach 1:
The patent introduces an intermediary mechanism by using indication information as a mediator between channel conditions and OAM mode selection. The network device receives structured indication information that simplifies the measurement process, converting complex multi-mode quality assessment into a manageable format that guides OAM mode selection without requiring direct measurement of all parameters
Solution Approach 2:
The patent segments the transmission process by separating target signal transmission from other signals, allowing dedicated measurement and indication for target signals. This segmentation enables focused quality measurement on specific signals while using multiple OAM modes for overall bandwidth expansion, reducing the complexity of measuring all transmissions simultaneously
