Abstract
The present invention relates to a method includes: implementing, by the board in the BBU1, frequency synchronization between a system clock of the board in the BBU1 and a system clock of the board in the BBU0 by using a synchronous Ethernet clock that is output by the board in the BBU0; and implementing, by the board in the BBU1, time synchronization between the system clock of the board in the BBU1 and the system clock of the board in the BBU0 by using an IEEE1588 clock that is output by the board in the BBU0. The present invention can enable the multimode base station to support more standards.
