Abstract: The present invention provides a method and a device for implementing synchronization between different systems. The method includes setting a starting time of an LTE TDD frame, where the starting time set for the LTE TDD frame is later than a starting time set for a WiMAX frame. The LTE TDD frame is transmitted after the starting time of the LTE TDD frame arrives. The WiMAX frame adopts a subframe ratio structure of 29:18, the LTE TDD frame adopts a subframe ratio structure of subframe configuration 1, and an UpPTS time slot and a last uplink symbol of a last uplink subframe which are in the LTE TDD frame are in a status of being knocked off.
