摘要：
The method for multiple TDD systems coexistence comprising steps of: a newly deployed system calculating a relative time offset Δt for a corresponding frame; the newly deployed system transmitting uplink and downlink signals based on a time reference information obtained by a summation of the relative time offset Δt and a time reference of an existing system. With the method proposed in present invention, uplink and downlink interference from adjacent frequency bands and from adjacent carriers in the same frequency band can be greatly reduced and a transmission time utility can be guaranteed for a newly deployed system.
