摘要： A signal transmission method in a Time Division Duplex (TDD) system is disclosed. The method comprises following steps: within a time length of a half-frame of a radio frame, base station transmits signal on a downlink special time slot, thereafter does not transmit signal on a Guard Period (GP), and then receives signal on an uplink special time slot; all time lengths of other uplink or downlink normal time slots for transmitting signal are equal; the total time length of the downlink special time slot, the guard period and the uplink special time slot is integer times of the time length of an uplink or downlink normal time slot. In addition, a frame structure adopted in the TDD system which corresponds to the method is disclosed. The present invention makes it flexible to set the duration of the GP and it is guaranteed that, even if a synchronization signal adopts power promotion, it will not bring great interference to uplink reception of other base stations; in addition, the utilization efficiency of the system is improved.

摘要： The present application discloses a dynamic sub-frame configuration method in the TDD system. The method includes: in the case that the uplink and downlink sub-frame configuration of a cell and the uplink and downlink sub-frame configuration of its neighboring cell are different in the configuration of a sub-frame, a part of resources on the sub-frame are made to be silent for the cell, and the resources on the sub-frame corresponding to the resources not silenced on the sub-frame for cell are made to be silent for the neighboring cell; or, a part of resources on the sub-frame are made to be silent for the neighboring cell, and the resources on the sub-frame corresponding to the resources not silenced on the sub-frame for the neighboring cell are made to be silent for the cell. The present application further provides a dynamic sub-frame configuration apparatus in the TDD system. Not only can the problem that inter-cell interference is introduced during sub-frame switching in the TDD system be solved, but also the normal uplink and downlink measurement can be guaranteed, without affecting ACK/NACK feedback and HARQ process, and meantime the frequency spectrum utilization ratio is increased.
