Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If all energy-saving configuration parameters (K0, K2, A-CSI-RS triggering offset) are configured to values greater than zero, then terminal energy-saving effect is improved, but service latency and quality of service may deteriorate
Solution Approach 1:
The patent implements dynamic configuration of energy-saving parameters by introducing a switch parameter that can be adjusted based on service requirements. When the switch is enabled, parameters K0, K2, and A-CSI-RS triggering offset are configured to values greater than zero to achieve energy-saving; when disabled, they are configured to zero to ensure low latency. This dynamic adjustment mechanism allows the system to adapt between energy-saving mode and low-latency mode according to real-time service needs.
Solution Approach 2:
The patent changes the values of configuration parameters (K0, K2, A-CSI-RS triggering offset) based on the switch state. When the energy-saving switch is enabled, these parameters are set to positive values to create time gaps between transmissions, allowing the terminal to enter micro sleep mode. When the switch is disabled, parameters are set to zero to eliminate delays. This parameter variation strategy directly addresses the contradiction between energy consumption and service latency.
2Use of energy by moving object
If energy-saving configuration parameters are configured to enable micro sleep mode, then terminal power consumption is reduced, but service quality and reliability may deteriorate
Solution Approach 1:
The patent introduces a dynamic switch mechanism that allows network side to adjust the energy-saving configuration based on service type and quality requirements. For high-reliability services, the switch can be disabled to maintain parameter values at zero, ensuring timely transmission. For low-priority services, the switch is enabled to achieve energy-saving. This dynamic control ensures service quality is maintained when needed while enabling energy-saving when acceptable.
Solution Approach 2:
The patent applies different energy-saving configurations to different service types or terminal scenarios through the switch mechanism. Rather than uniformly applying energy-saving parameters to all services, the system can selectively enable energy-saving mode for specific service types or terminals with lower quality requirements, while maintaining high-quality service for critical applications. This localized application of energy-saving parameters resolves the contradiction between power consumption and service quality.
3Use of energy by moving object
If parameters K0, K2, and A-CSI-RS triggering offset are configured collectively for energy-saving, then terminal energy efficiency is improved, but device complexity and configuration complexity increase
Solution Approach 1:
The patent combines multiple energy-saving parameters (K0, K2, A-CSI-RS triggering offset) into a unified configuration controlled by a single switch. Instead of requiring separate optimization of each parameter, the network side can enable or disable the energy-saving mode through one switch, which automatically adjusts all relevant parameters together. This merging approach simplifies the configuration process while achieving comprehensive energy-saving effects across multiple parameters.
Solution Approach 2:
The patent pre-configures the relationship between the switch and multiple parameters in advance. When the switch is enabled, the system has already predetermined that parameters K0, K2, and A-CSI-RS triggering offset will be set to positive values. This preliminary configuration eliminates the need for complex real-time calculations or separate parameter adjustments, reducing configuration complexity while maintaining energy-saving effectiveness.
