Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent applies parameter changes by establishing a specific mathematical relationship between dynamic time offset and semi-static time offset parameters. By requiring that semi-static time offset values belong to the value set of dynamic time offset, the patent ensures both terminals and network devices use consistent parameter interpretations, thereby resolving the information understanding inconsistency while maintaining feedback reliability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent achieves equipotentiality in information understanding by ensuring that terminals and network devices operate with the same time offset parameter sets. The configuration information mechanism allows both sides to have identical parameter configurations, eliminating understanding discrepancies and ensuring reliable feedback communication

Inventive Principle:

Principle #12Equipotentiality
