Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one antenna panel is used for signal transmission, then the device complexity is reduced and ease of operation is improved, but the productivity and adaptability for multi-point transmission and multi-carrier deployment are limited
Solution Approach 1:
The patent segments the antenna system into multiple independent antenna panels, each capable of simultaneous signal transmission. The terminal device is configured to support multiple antenna panels, allowing each panel to independently transmit signals for multi-point transmission and multi-carrier deployment, thereby improving productivity while maintaining manageable complexity through modular architecture
Solution Approach 2:
The patent implements dynamic antenna panel indication mechanisms where the terminal can dynamically indicate which antenna panels are available for transmission and the base station can dynamically select appropriate panels based on current transmission needs. This dynamic configuration allows the system to adapt between single-panel and multi-panel operations, improving productivity when needed while maintaining operational simplicity when not required
2Adaptability or versatility
If multiple antenna panels transmit signals simultaneously, then the adaptability for multi-point transmission and multi-carrier deployment is improved, but the device complexity increases due to lack of scheduling mechanisms
Solution Approach 1:
The patent implements feedback mechanisms where the terminal device feeds back antenna panel indication information to the base station, indicating which antenna panels are available and their transmission capabilities. The base station uses this feedback to make informed decisions about signal scheduling across multiple panels, enabling adaptability for multi-point transmission while managing complexity through information-based coordination
Solution Approach 2:
The patent introduces antenna panel indication information as an intermediary element that mediates between the terminal's antenna panel capabilities and the base station's signal scheduling decisions. This intermediary information structure allows the system to coordinate multiple antenna panels without requiring complex direct communication and coordination protocols between all components, thereby improving adaptability while controlling scheduling complexity
