Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If hardware correction based on first information from correction circuit is used, then correction speed is improved, but correction precision deteriorates due to inability to reflect channel quality outside measurement range
Solution Approach 1:
The patent combines hardware correction (first correction result from correction circuit) and air interface correction (second correction result from terminal device feedback) into a joint correction mechanism. The network device receives both correction results and determines final correction parameters by combining them, thereby achieving both fast correction speed from hardware and high precision from air interface measurement.
Solution Approach 2:
The patent introduces a joint correction determination mechanism as an intermediary that processes both hardware correction results and air interface correction results. This intermediary combines the advantages of both correction methods and determines the final correction parameters, resolving the contradiction between speed and precision.
2Measurement precision
If air interface correction based on second information from terminal devices is used, then correction precision is improved, but processing complexity increases due to additional feedback mechanisms
Solution Approach 1:
The patent implements selective joint correction determination rather than always combining both correction methods. The network device determines whether to perform joint correction based on actual channel conditions and requirements, using air interface correction information only when needed to improve precision, thereby avoiding unnecessary processing complexity while maintaining high precision when required.
3Productivity
If only hardware correction is performed, then processing efficiency is improved, but correction accuracy deteriorates due to component variations and temperature fluctuations
Solution Approach 1:
The patent implements a feedback mechanism where terminal devices measure actual channel quality through air interface transmission and feed back correction information to the network device. This feedback loop enables the system to detect and correct inaccuracies caused by component variations and temperature fluctuations, thereby improving correction accuracy while maintaining processing efficiency through selective application.
