A kind of TDD cell is the method and system of Terminal for service

The invention discloses a kind of method that TDD cell is Terminal for service, described method includes: in advance on TDD eNB, the community producing interference between frequency band and FDD frequency band is set to the uplink cells being served only for transmitting upstream data or the descending community being served only for transmitting downlink data, and in described eNB, preserves configuration information and the configuration information of descending community of described uplink cells；The configuration information of described uplink cells and the configuration information of descending community are sent to UE by described eNB；UE receives configuration information and the configuration information of descending community of described uplink cells, and is carried out data transmission with described eNB by described uplink cells and/or descending community.The invention also discloses a kind of is the system of Terminal for service by TDD cell, solve the interference between frequency band of FDD system and TDD system, it is achieved FDD coexists with TDD system, and frequency spectrum resource can be made full use of, ensure the high usage of frequency spectrum resource, save resource.
