Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device switches the antenna panel after receiving scheduling signaling, then the beam can be switched to the correct direction, but the panel switching time causes the scheduled resource to arrive before the panel is ready, resulting in transmission failure
Solution Approach 1:
The network device sends panel activation commands in advance before the scheduled resource arrives. The terminal device activates the target panel prior to the resource arrival time, ensuring the panel is ready before the signal needs to be transmitted or received. This preliminary activation eliminates the timing conflict between panel switching and resource arrival.
Solution Approach 2:
The system dynamically adjusts the panel activation timing based on the scheduled resource timing. The network device determines the appropriate activation time considering the terminal's panel switching capability, and sends activation commands at optimal moments to ensure panels are ready exactly when needed, adapting to different transmission scenarios.
2Adaptability or versatility
If multiple antenna panels are configured for wide area coverage, then beam diversity is improved, but the complexity of panel management and switching increases
Solution Approach 1:
The network device pre-configures multiple antenna panels and their corresponding beam information before transmission. By preparing the panel configuration in advance and sending activation commands proactively, the system manages multiple panels efficiently without requiring complex real-time switching decisions at the terminal.
Solution Approach 2:
The terminal device feeds back its panel capability information and switching capability to the network device. The network device uses this feedback to determine appropriate panel activation strategies, adapting the panel management approach to the terminal's actual capabilities, thereby reducing unnecessary complexity.
