Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink data transmission uses multiple transmission-reception-points with independent parameter configuration, then reliability of uplink data communications is improved, but device complexity increases
Solution Approach 1:
The patent segments the uplink transmission by dividing it into multiple transmission-reception-point (TRP) paths, where each TRP is configured with independent parameters. This segmentation allows the transmission to be distributed across multiple independent channels, improving reliability through diversity while managing complexity by treating each TRP as a separate configurable entity
Solution Approach 2:
The patent implements dynamic parameter configuration for each TRP, allowing the network to independently adjust transmission parameters (such as power, timing, frequency) for each transmission-reception-point based on channel conditions. This dynamic adaptation improves reliability by optimizing each path independently while maintaining manageable system complexity through standardized configuration mechanisms
2Reliability
If uplink data transmission uses multiple transmission-reception-points, then beam diversity is enhanced, but use of energy increases
Solution Approach 1:
The patent applies local quality by configuring different transmission parameters for each TRP based on local channel conditions. Each TRP receives customized configuration information tailored to its specific propagation path, allowing the system to enhance beam diversity through localized optimization while avoiding unnecessary energy expenditure on suboptimal paths
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting transmission parameters (power levels, resource allocation, modulation schemes) for each TRP based on channel quality indicators. This allows the system to enhance beam diversity by adapting parameters locally for each transmission path while minimizing overall energy consumption by reducing power on poorer channels and concentrating it on better channels
