The invention provides a current generating method and device of a TDD communication system. The method comprises that an evolution base station eNodeB receives a detection reference signal SRS from user terminal UE, and first weight information is generated; the eNodeB adjusts a channel state indication information reference signal CSI-RS sent to the UE according to the first weight information,so that the UE back feeds channel quality information on the basis of the CSI-RS; and the eNodeB generates second weight information on the basis of the first weight information and the received channel quality information back fed by the UE, and adjusts down service data according to the second weight information. On the basis of a present non-turn terminal, the current generating method and device of the TDD communication system use formed CSI-RS, combine open-loop and closed-loop technologies, realize high-speed accurately formed SU-MIMO, and approach the SU-MIMO performance of a turn terminal.
