Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If beam selection is optimized for high-speed communication, then data rate is improved, but latency increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring beam information and packet delay budgets before communication occurs. The network side device configures beam parameters and PDB values in advance, allowing the terminal device to select beams and manage packets without real-time computation, thereby reducing latency while maintaining high data rates.
Solution Approach 2:
The patent implements dynamics by enabling flexible adjustment of beam selection based on varying packet delay budgets and communication conditions. The system dynamically adapts the number of selectable beams and packet handling strategies according to real-time requirements, optimizing the balance between data rate and latency for different scenarios.
2Loss of time
If packet delay budget is reduced for low-latency communication, then latency is improved, but available beams for selection decrease
Solution Approach 1:
The patent applies parameter changes by adjusting the packet delay budget parameter based on the number of available beams and communication conditions. When fewer beams are available or channel conditions are poor, the system increases the PDB to allow more time for beam selection and packet transmission, thereby maintaining adaptability while meeting latency requirements.
3Reliability
If maximum number of selectable beams is increased, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies partial action by selectively enabling beam selection based on actual communication needs and channel conditions. Instead of always considering the maximum number of possible beams, the system activates only the necessary number of beams for each transmission opportunity, reducing processing complexity while maintaining adequate reliability through sufficient beam diversity when needed.
