Abstract:
1. An implementation method of a multimode base station, wherein the multimode base station is at least integrated with a first baseband unit BBU0 and a second base band unit BBU1, wherein a board of at least one standard is overlaid in the BBU0 and the BBU1 each; and the board in the BBU0 and the board in the BBU1 each are connected to a common-mode radio frequency module through a communication interface, the method comprising: implementing, by a 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 a 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.
