Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transmission parameter sets are configured for different CORESET pools to enable simultaneous uplink transmissions, then the system capacity and data rate are improved, but the device complexity and configuration overhead increase
Solution Approach 1:
The patent segments the uplink transmission configuration by introducing multiple transmission parameter sets (first transmission parameter set and second transmission parameter set) corresponding to different CORESET pools. Each parameter set contains independent configuration information for simultaneous uplink transmissions, allowing the system to handle multiple transmission tasks with distinct parameters without interference, thereby resolving the contradiction between system capacity and configuration complexity.
Solution Approach 2:
The patent implements dynamic selection of transmission parameter sets based on the CORESET pool associated with each uplink transmission. The terminal device dynamically determines which parameter set to use for each transmission occasion, enabling flexible adaptation to different transmission scenarios while maintaining clear configuration management through the CORESET pool association mechanism.
2Speed
If multiple transmission parameter sets are used for simultaneous uplink transmissions, then the data rate and service speed are improved, but the information management complexity increases
Solution Approach 1:
The patent establishes a feedback mechanism where the network device configures multiple transmission parameter sets and associates them with different CORESET pools. The terminal device receives downlink control information indicating which CORESET pool to monitor, provides feedback on transmission status, and the network adjusts parameter configurations accordingly. This feedback loop enables efficient management of multiple parameter sets without information loss.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple transmission parameter sets before simultaneous uplink transmissions occur. The network device prepares the first and second transmission parameter sets in advance, associating each with specific CORESET pools, so that when simultaneous transmissions are needed, the terminal can immediately select the appropriate pre-configured parameter set without complex real-time decision-making.
3Use of energy by moving object
If simultaneous uplink transmissions related to multiple CORESET pools are performed, then the energy efficiency is improved, but the transmission reliability may deteriorate due to increased interference
Solution Approach 1:
The patent applies local quality by configuring distinct transmission parameter sets for different CORESET pools, where each parameter set is optimized for specific transmission conditions and target entities. This allows different parts of the uplink transmission to have different quality characteristics (power, modulation, coding), enabling simultaneous transmissions to coexist with minimized interference while maintaining overall reliability.
Solution Approach 2:
The patent utilizes parameter changes by allowing the network to independently adjust transmission parameters (such as power control, modulation scheme, resource allocation) in each transmission parameter set. This enables dynamic optimization of each simultaneous transmission's parameters to balance energy efficiency and reliability, preventing interference-induced reliability deterioration while maintaining energy efficiency.
