Disclosed is a dynamic frame structure distribution method for a time division duplexing (TDD) system. The method comprises: an evolved Node B (eNB) sending to user equipment (UE) a radio resource control (RRC) instruction for entering a state of dynamically configuring a frame structure, and sending configuration information about the frame structure via a physical downlink control channel (PDCCH); and after receiving the instruction, the UE detecting configuration information about the frame structure in the PDCCH, and configuring a frame structure used in the next configuration cycle in accordance with the detected configuration information. Also disclosed at the same time is a TDD system dynamic frame structure distribution system and an eNB. The solution of the present invention can shorten the changing cycle of a TDD system frame structure, and better support the transmission of a symmetric service. |
