Document Type and Number:
WIPO Patent Application WO/2017/054554
Kind Code:
A1
Abstract:
A clock synchronization method, device, and communication apparatus. The method comprises: determining, according to a reference clock source, a software clock initial time for a node desiring to perform a data transceiving operation; determining, according to the determined software clock initial time and a data transceiving rhythm, a software clock current time after the data transceiving operation; and adjusting, according to a time difference between the software clock current time and a current time of the reference clock source, the data transceiving rhythm, such that an absolute value of the time difference is smaller than a predetermined threshold. Embodiments of the present invention realize clock synchronization without customized hardware, thus simplifying the manufacturing, use, and maintenance of a communication apparatus, such as a base station controller, a baseband unit (BBU), and a remote radio unit (RRU).
