Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple beams and panels are used for uplink transmission, then data rate is improved, but device complexity increases
Solution Approach 1:
The patent segments the uplink transmission system into multiple independent panels, where each panel can perform transmission independently. This allows the system to achieve high data rates through parallel transmissions while managing complexity by dividing the overall system into manageable modular units with standardized interfaces.
Solution Approach 2:
The patent introduces spatial dimensionality by utilizing multiple panels and beams in different spatial directions. This dimensional expansion allows simultaneous transmissions through different spatial paths, increasing data rate without proportionally increasing processing complexity at any single point in the system.
2Productivity
If multiple beams and panels are used for uplink transmission, then data rate is improved, but switching delay increases
Solution Approach 1:
The patent performs preliminary actions by pre-configuring multiple panels and their associated beamforming parameters in advance. Capability information and configuration information are exchanged beforehand to establish ready-to-use transmission paths, eliminating the need for time-consuming switching operations during actual data transmission.
Solution Approach 2:
The patent merges the operations of multiple panels into a coordinated simultaneous transmission scheme. By combining the capabilities of multiple panels and configuring them to work together, the system achieves high data rates through parallel transmissions without requiring sequential switching between panels.
3Productivity
If multiple beams and panels are used for uplink transmission, then resource utilization is improved, but device complexity increases
Solution Approach 1:
The patent implements universal panel configurations where each panel is designed with multi-functionality to handle different transmission tasks. The standardized capability information and configuration information formats allow panels to be universally deployed and managed, improving resource utilization while controlling complexity through reuse of proven designs.
