Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a configuration mechanism for transmission scheme is applied in NR system, then the reliability of data transmission is improved, but the device complexity increases due to multiple transmission schemes and spatial parameters
Solution Approach 1:
The patent segments the transmission configuration into multiple independent transmission schemes (first transmission scheme, second transmission scheme) that can be separately configured and applied to different spatial parameters. This allows the system to manage complexity by dividing the overall transmission process into manageable segments rather than handling all parameters simultaneously.
Solution Approach 2:
The patent implements dynamic selection of transmission schemes based on the number of spatial parameters. The terminal device determines which transmission scheme to use dynamically according to the actual spatial parameter configuration, allowing the system to adapt to different scenarios and optimize performance without being locked into a fixed complex configuration.
2Reliability
If multiple transmission schemes are configured for multi-TRP transmission, then the diversity gain is improved, but the transmission delay increases due to scheme determination and switching
Solution Approach 1:
The patent performs preliminary configuration of multiple transmission schemes before actual data transmission. The network device pre-configures the first and second transmission schemes, and the terminal device pre-determines the mapping relationships between schemes and spatial parameters. This preliminary setup enables faster real-time decision-making and reduces transmission delay during actual operation.
Solution Approach 2:
The patent enables dynamic determination of transmission schemes based on real-time spatial parameter conditions. The terminal device dynamically selects the appropriate transmission scheme according to the number of spatial parameters associated with the information to be transmitted, optimizing the balance between diversity gain and transmission delay for each specific transmission instance.
