Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a lightweight method with high compression ratio is used, then transmission resources are saved, but model precision is greatly affected
Solution Approach 1:
The patent implements dynamic selection of lightweight methods and policy configurations based on uplink transmission rate conditions. The network device determines appropriate lightweight processing parameters by evaluating current channel state information, allowing the system to adapt compression ratios to transmission conditions rather than using a fixed high compression ratio, thus balancing resource savings with precision maintenance
Solution Approach 2:
The patent changes key parameters including compression ratio, lightweight method type, and policy configuration based on uplink transmission rate conditions. By adjusting these parameters dynamically according to channel state, the system optimizes the balance between transmission efficiency and model precision for different network conditions
2Measurement precision
If a lightweight method with low compression ratio is used, then model precision is maintained, but transmission resources are wasted and efficiency is reduced
Solution Approach 1:
The system dynamically adjusts the compression ratio and lightweight method selection based on real-time uplink transmission rate conditions. When transmission conditions are good, lower compression ratios are used to maintain precision; when conditions are poor, higher compression ratios are applied to improve efficiency, achieving optimal balance adaptively
Solution Approach 2:
The patent modifies transmission parameters including compression ratio and lightweight processing configuration based on channel state evaluation. This parameter adaptation allows the system to use lower compression ratios when transmission capacity is sufficient, maintaining precision while avoiding unnecessary resource waste
3Speed
If lightweight processing is performed without considering uplink transmission capability, then processing speed is improved, but transmission delay requirements cannot be met and precision is lost
Solution Approach 1:
The network device performs preliminary evaluation of uplink channel state information before determining lightweight processing parameters. This advance assessment allows the system to pre-select appropriate compression ratios and methods that will meet transmission delay requirements, preventing precision loss and delay violations
Solution Approach 2:
The system uses feedback from uplink channel state information to adjust lightweight processing configurations. By continuously monitoring transmission conditions and adapting parameters accordingly, the system ensures that processing speed optimizations do not compromise transmission delay requirements or model precision
Data Source
AI summary
This application provides a method and a related communication apparatus applicable to the communication field. In the method, a network device receives a first notification message sent by a terminal device, where the first notification message indicates that the terminal device has completed training on a target model, and the first notification message includes a model name corresponding to the target model. The network device then determines policy information based on the uplink channel state information of the terminal device; and sends a lightweight indication message to the terminal device.
