Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If network devices adjust antenna configurations for energy-saving purposes, then energy consumption is reduced, but CSI measurement accuracy deteriorates
Solution Approach 1:
The patent segments the CSI-RS resource configuration into multiple sub-configurations, each associated with different antenna configurations. This allows the terminal to receive and process multiple sets of configuration information corresponding to different antenna states, enabling accurate CSI measurement even when the network dynamically adjusts antenna configurations for energy saving.
Solution Approach 2:
The patent introduces dynamic adjustment mechanisms where the network can switch between different antenna configurations based on traffic conditions and energy saving requirements. The terminal equipment dynamically receives and processes CSI-RS resource configuration information corresponding to these changing configurations, maintaining measurement accuracy while enabling energy conservation.
2Measurement precision
If multiple sub-configurations are configured for CSI-RS resources, then CSI measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal configuration framework where the same CSI-RS resource configuration structure can support multiple sub-configurations with different antenna settings. This multi-functional approach allows the system to maintain a unified configuration mechanism while accommodating various antenna configurations for different measurement scenarios.
Solution Approach 2:
The patent implements a nested configuration structure where sub-configurations are organized within the main CSI-RS resource configuration framework. Each sub-configuration contains specific antenna configuration parameters nested within the overall configuration hierarchy, allowing for manageable organization of complex configuration information.
3Reliability
If network devices operate continuously to provide 5G services, then service availability is improved, but energy consumption increases
Solution Approach 1:
The patent enables periodic or dynamic adjustment of antenna configurations based on traffic patterns and network load conditions. The network can switch between different antenna configurations periodically or on-demand, allowing energy saving during low-traffic periods while maintaining service availability during high-traffic periods.
Solution Approach 2:
The patent utilizes parameter changes in antenna configurations (such as beam directions, antenna activation patterns) to adapt the network's energy consumption characteristics. By dynamically changing these parameters based on service demands, the network can maintain reliability when needed while reducing energy consumption during quieter periods.
