Title:
CLOCK SYNCHRONIZATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/037428
Kind Code:
A1
Abstract:
The present application provides a clock synchronization method and apparatus. In the technical solutions of the present application, a third message simultaneously carries information that can directly or indirectly indicate a first time stamp and a second time stamp, so that time stamp exchange between a network device and a first terminal can be implemented by means of 3 messages. In this way, a time interval between a first message and a second message can be reduced, and LBT only needs to be executed 3 times, reducing the number of times that the LBT is executed. Therefore, the technical solutions of the embodiments of the present application help to improve the accuracy of clock offset estimation, thereby improving the accuracy of clock synchronization.
