Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed time division multiplexing parameters are set by nodes, then device complexity is reduced, but adaptability to real-time changes in application scenarios deteriorates
Solution Approach 1:
The patent implements dynamic time division multiplexing parameters that can be adjusted in real-time based on network conditions and application requirements. The system transitions from static fixed parameters to dynamic adaptive parameters, allowing nodes to modify time slot allocations, guard periods, and synchronization settings according to changing traffic patterns and service quality requirements.
Solution Approach 2:
The system enables modification of key time division multiplexing parameters including time slot duration, guard period length, and synchronization timing. These parameter changes allow the network to adapt to different application scenarios such as real-time communication, data transfer, and IoT applications, resolving the contradiction between fixed configuration simplicity and adaptive performance.
2Ease of operation
If nodes use independent fixed time division multiplexing parameters, then ease of operation is improved, but packet loss increases due to synchronization issues
Solution Approach 1:
The patent implements a feedback mechanism where nodes exchange time division multiplexing parameter information and synchronization status. Through feedback messages, nodes learn about each other's parameter configurations and adjust their own settings to maintain proper synchronization, thereby reducing packet loss while keeping operation simple through automated adjustments.
Solution Approach 2:
The system introduces a coordination mechanism that acts as an intermediary for parameter synchronization. This intermediary function ensures that time division multiplexing parameters are properly aligned across nodes, preventing the packet loss that occurs when nodes operate with independent unsynchronized parameters, while maintaining ease of operation through centralized coordination.
3Device complexity
If fixed time division multiplexing parameters are used, then device complexity is reduced, but spectrum resource utilization deteriorates
Solution Approach 1:
The system implements dynamic spectrum resource allocation through adaptive time division multiplexing parameters. Time slot durations and frequencies are adjusted in real-time based on traffic demand and network conditions, maximizing spectrum utilization efficiency while maintaining manageable device complexity through automated parameter optimization algorithms.
Solution Approach 2:
The patent enables dynamic modification of time division multiplexing parameters to optimize spectrum usage. By changing parameters such as time slot allocation ratios, guard period lengths, and frequency hopping patterns based on network conditions, the system achieves high spectrum resource utilization without requiring complex manual configuration, as the adjustments are made automatically based on predefined optimization criteria.
