Patent ID: 8483103

Claim:
A method for determining an offset of a time slot, comprising: synchronizing a first TDD system with a second TDD system; and determining an offset of a time slot of the second TDD system according to a time difference between time slots of the first TDD system and the second TDD system, wherein, determining the offset of the time slot of the second TDD system according to the time difference between the time slots of the first TDD system and the second TDD system comprises: determining a first switch point between uplink and downlink time slots of the first TDD system; determining a second switch point between uplink and downlink time slots of the second TDD system; and providing a time difference between the first switch point and the second switch point as the offset of each time slot of the second TDD system: wherein, the method further comprises, after determining the offset of the time slot of the second TDD system according to the time difference between the time slots of the first TDD system and second TDD system: adjusting the length of at least one of an UpPTS and a DwPTS in a special time slot field of the second TDD system if a GP in the special time slot field of the second TDD system after being offset does not overlap a GP in a special time slot field of the first TDD system, and broadcasting special time slot configuration information of the second TDD system after being adjusted.
