The invention discloses a method and a device for sending synchronous signal sequences, wherein the method comprises: respectively determining the Offset k which is the offset value of at least one sweep point corresponding to the center frequency of the carrier frequency and is relative to the center frequency on the scheduled direction; shifting the synchronous signal sequences according to the offset value, and shifting at least one data at the tail end on the opposite direction of the scheduled direction to the tail end of the scheduled direction of the synchronous signal sequences; aligning the two ends of the shifted synchronous signal sequences with the two ends of the un-shifted synchronous signal sequences; and sending the shifted synchronous signal sequences. With the technical proposal of the invention, by cyclically shifting the synchronous signal sequences sent by the transmitting end, the transmitting end can access any carrier frequency in the LTE-Advanced system, compared with the prior art, the method does not need to change the standard, not only can meet the requirement for upgrading the system, but also does not influence the performance of the receiving end.
