Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous uplink transmission using multiple panels is implemented, then throughput and reliability are improved, but system complexity increases due to lack of control mechanisms
Solution Approach 1:
The terminal reports its capability to perform simultaneous uplink transmission using multiple panels in advance. This preliminary capability indication allows the base station to prepare appropriate scheduling configurations before actual transmission occurs, avoiding complex real-time control decisions and reducing overall system complexity while enabling high throughput.
Solution Approach 2:
The base station receives capability reports from the terminal regarding simultaneous multi-panel transmission support, uses this feedback information to configure appropriate transmission parameters, and adjusts scheduling decisions accordingly. This feedback mechanism enables the system to adapt to terminal capabilities without requiring complex built-in control logic at the terminal end.
2Productivity
If simultaneous uplink transmission using multiple panels is performed without adequate control studies, then transmission capacity increases, but system performance degrades due to lack of optimization
Solution Approach 1:
The patent defines specific parameters for controlling simultaneous uplink transmission, including time period determination based on capability reports and indication signals. By establishing clear parameter specifications for when and how multi-panel transmission should occur, the system achieves both high transmission capacity and reliable performance through optimized control mechanisms.
