Method and device for transmitting synchronizing signals

The invention discloses a method for transmitting synchronizing signals. The method comprises the steps that a first communication node transmits a synchronizing signal S1 on an X frame and transmits a synchronizing signal S2 on an (X+K) frame, wherein the synchronizing signal S1 and the synchronizing signal S2 are different, and K is not less than 1; or, the first communication node transmits the synchronizing signal S1 on the X frame, and S is in a main and auxiliary synchronizing signal structure. The invention also discloses a device for transmitting the synchronizing signals. According to the device for transmitting the synchronizing signals and the method for transmitting the synchronizing signals, a problem of high terminal realizing cost caused by a synchronizing channel standard in the existing wireless communication can be solved.
