Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If BWP switching is performed frequently to adapt to varying data traffic patterns, then signal transmission efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent changes the parameter of BWP configuration by introducing a second BWP specifically designed with narrower bandwidth for energy saving. The system dynamically switches between the first BWP (wider bandwidth for high data traffic) and the second BWP (narrower bandwidth for low data traffic), thereby adapting bandwidth parameters to traffic conditions while reducing energy consumption during low-activity periods.
Solution Approach 2:
The patent implements dynamic BWP switching based on buffer status and traffic patterns. The network device determines when to switch between BWPs by monitoring data buffer conditions, enabling the system to adapt its bandwidth configuration dynamically rather than using a fixed configuration, thus balancing transmission efficiency and energy consumption.
2Loss of energy
If BWP switching is performed to reduce energy consumption during low traffic, then energy efficiency is improved, but transmission performance may deteriorate
Solution Approach 1:
The patent changes the bandwidth parameter by configuring a second BWP with narrower bandwidth specifically for energy saving mode. This parameter change allows the system to reduce energy consumption while maintaining adequate transmission performance for low-traffic scenarios, as the narrower bandwidth is sufficient for maintaining connectivity and handling minimal data traffic.
Solution Approach 2:
The patent implements dynamic switching between BWPs based on buffer status reports and traffic patterns. When traffic increases, the system switches back to the first BWP with wider bandwidth, ensuring transmission performance is maintained when needed. This dynamic adaptation prevents performance deterioration by only using the energy-saving BWP during appropriate low-traffic conditions.
