The method includes: sending P-SCH signals of synchronization signals on the third symbol of a DwPTS; sending S-SCH signals of the synchronization signals on the last OFDM symbols of time slot 1 and time slot 11. The present invention solves the problem that the P-SCH signal sending interferes with the pilot sending of the first and second antenna in the prior art, guarantees that the location of the pilot in the DwPTS does not change, and reduces the system complexity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus of sending synchronization signals in TDD systems","description":"The present invention discloses a method and apparatus of sending synchronization signals in TDD systems.
