Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified transmission scheme is used for all channels, then system complexity is reduced, but the ability to satisfy diverse service demands (time delay, reliability, throughput) deteriorates
Solution Approach 1:
The patent segments the transmission scheme into multiple priority levels (first priority and second priority transmission schemes). Different channels are assigned to different priority levels based on their service requirements, allowing the system to handle diverse service demands while maintaining manageable complexity through structured classification.
Solution Approach 2:
The patent applies local quality by assigning different transmission scheme characteristics to different channels based on their specific service requirements. High-priority channels (e.g., URLLC) receive transmission schemes optimized for low latency and high reliability, while other channels use different schemes, ensuring each channel receives locally optimized treatment.
2Adaptability or versatility
If different transmission schemes are used for different channels, then service demand satisfaction is improved, but system complexity increases
Solution Approach 1:
The patent reduces complexity by segmenting transmission schemes into a limited number of priority levels (first and second priority schemes) rather than creating entirely independent schemes for each channel. This structured segmentation provides adaptability for different services while constraining complexity through standardized priority-based classification.
Solution Approach 2:
The patent creates universal transmission scheme templates for different priority levels that can be applied across multiple channels. The first priority transmission scheme serves multiple high-priority channels with similar requirements, and the second priority scheme serves other channels, providing multi-functional coverage that reduces overall system complexity.
3Ease of operation
If system resources are allocated uniformly, then resource allocation simplicity is maintained, but the ability to optimize for different service types (eMBB, URLLC, mMTC) deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority levels and associating different service types (eMBB, URLLC, mMTC) with specific priority levels before transmission occurs. The network device determines channel priorities in advance based on service requirements, and terminal devices are pre-configured with corresponding transmission schemes, enabling efficient resource allocation without complex real-time decisions.
Solution Approach 2:
The patent optimizes resource allocation by changing key transmission parameters (time delay requirements, reliability thresholds, throughput targets) based on channel priority. High-priority channels receive parameter configurations optimized for low latency and high reliability, while other channels use different parameter sets, allowing the system to optimize for different service types while maintaining clear operational rules.
