Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a terminal device performs measurement and demodulation on multiple beams of a neighboring cell to obtain polarization indication messages, then the terminal device can acquire polarization information, but measurement overheads are increased
Solution Approach 1:
The network device sends polarization indication messages to the terminal device in advance, before the terminal device needs to perform measurements. This allows the terminal device to obtain polarization information without having to conduct extensive measurements, thereby reducing measurement overheads and time consumption.
2Adaptability or versatility
If a terminal device switches polarization mode to obtain neighboring cell indication messages, then the terminal device can access polarization information, but service interruption occurs due to switching delay
Solution Approach 1:
The network device sends polarization switching indication messages to the terminal device in advance, allowing the terminal device to switch polarization modes before service interruption occurs. This preliminary notification enables the terminal device to prepare for the polarization switch, maintaining service continuity and avoiding interruption.
3Adaptability or versatility
If a terminal device switches polarization mode in conventional technology, then the terminal device can adjust to different polarization requirements, but cell re-searching and repeated synchronization processes are triggered
Solution Approach 1:
The network device provides feedback to the terminal device through polarization indication messages, informing the terminal device of the required polarization mode for neighboring cells. This feedback mechanism allows the terminal device to adjust its polarization mode without triggering cell re-searching or repeated synchronization processes, thereby maintaining network efficiency.
