Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the network device dynamically adjusts the number of antennas for energy saving, then energy consumption is reduced, but the channel changes causing inaccurate or untimely CSI measurement results
Solution Approach 1:
The network device pre-configures multiple antenna port indication patterns and informs the terminal equipment in advance. When adjusting antenna configuration for energy saving, the terminal can immediately select from pre-defined patterns without waiting for reconfiguration, ensuring timely and accurate CSI measurements even as antennas are dynamically adjusted.
Solution Approach 2:
The patent introduces dynamic antenna port indication patterns that allow the terminal equipment to adapt its CSI measurement configuration based on current antenna deployment. The terminal selects appropriate patterns from multiple pre-configured options, enabling flexible adaptation to dynamic antenna adjustments while maintaining measurement accuracy.
2Loss of energy
If the network device dynamically adjusts antenna configuration, then energy saving is achieved, but transmission performance is affected due to inaccurate CSI reports
Solution Approach 1:
Multiple antenna port indication patterns are pre-configured and communicated to the terminal in advance. This allows the terminal to quickly adapt to antenna configuration changes without compromising transmission performance, as the appropriate measurement pattern is already available for immediate use.
Solution Approach 2:
The patent changes the parameter of antenna port indication from a fixed single pattern to multiple configurable patterns. This allows the system to select different measurement configurations based on current antenna deployment, maintaining transmission reliability while enabling energy-saving antenna adjustments.
3Loss of information
If the terminal performs CSI measurement on all configured ports, then measurement completeness is improved, but measurement efficiency decreases due to dynamic antenna adjustments
Solution Approach 1:
The patent extracts only the necessary antenna ports for CSI measurement based on current antenna deployment. Instead of measuring all configured ports, the terminal uses the antenna port indication pattern to identify and measure only the actively deployed ports, improving measurement efficiency while maintaining completeness of relevant information.
Solution Approach 2:
The antenna port indication pattern enables dynamic selection of which ports to measure. The terminal adapts its measurement scope based on the indicated pattern, measuring only the currently deployed antenna ports rather than all configured ports, thus improving efficiency without sacrificing measurement completeness for active ports.
