摘要:
A method for determining a data transmission offset includes: synchronizing a first time division duplex TDD system with a second TDD system (a500); determining a transmission timing advance of a user terminal according to a deviation between random access time and desired time of the user equipment during establishing the uplink synchronization of the second TDD system (a501); determining an offset of a time slot of the second TDD system according to a time difference between the time slots of the first TDD system and the second TDD system (a502); and obtaining a data transmission offset of the time slot by adding the determined offset of the time slot to the determined transmission timing advance (a503). A system and a base station for determining a data transmission offset are provided.
