Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transmission time-delay compensation is performed, then time synchronization accuracy is improved, but device complexity increases
Solution Approach 1:
The terminal device autonomously determines whether to perform transmission time-delay compensation by receiving first information and evaluating conditions locally, without requiring complex network-side control or coordination with other devices. This self-service approach enables the terminal to independently make compensation decisions based on received parameters, thereby improving time synchronization accuracy while avoiding the complexity overhead of centralized control mechanisms.
2Measurement precision
If transmission time-delay compensation is always performed, then time synchronization accuracy is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts whether transmission time-delay compensation is performed based on real-time conditions. The terminal device receives first information containing parameters that indicate whether compensation is needed, and only performs compensation when conditions warrant it. This dynamic, conditional approach ensures time synchronization accuracy is maintained when necessary while avoiding unnecessary energy consumption during periods when compensation is not required.
3Measurement precision
If transmission time-delay compensation parameters are provided, then time synchronization accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential first information needed for the terminal device to determine whether transmission time-delay compensation is required. Rather than transmitting complete compensation parameters or continuous synchronization data, the system sends minimal information that enables the terminal to make autonomous compensation decisions. This extraction approach provides the necessary time synchronization accuracy while minimizing information transmission overhead.

AI summary
A time-delay compensation method and apparatus, and a device. The method comprises: a time-delay compensation method, which is applied to a terminal device. The time-delay compensation method comprises: receiving first information, the first information being used for the terminal device to determine whether to perform a transmission time-delay compensation; and determining whether to perform the transmission time-delay compensation according to the first information. In the present application, the terminal device determines, according to the first information sent by a network device, whether a transmission time-delay compensation is required, so as to solve the problem in the prior art that when transmission time-delay compensation is performed is unknown, so that service transmission in a communications network can achieve accuracy requirements of time synchronization.
