Abstract
A synchronization information sending method, a synchronization information receiving method, a base station, and a communications node are provided. The sending method includes: obtaining, by a communications node, a pulse per second PPS; obtaining, by the communications node, a first time Tbased on the PPS; obtaining, by the communications node, a second time Tbased on the subframe; determining, by the communications node, a first time difference TDbased on the first time Tand the second time T; obtaining, by the communications node, a second time difference TDbased on the first time difference TDand the TA. Different base stations use a same pulse per second PPS as a reference to adjust a sending time, a radio frame number, and a subframe number of a subframe, so that the different base stations are synchronized with each other.
