A data transmission method and system used for terminal to decode data flow correctly, and the method comprises as follows: according to the determined position of each data flow's downlink control information in the same downlink control signaling, the base station (BS) places each data flow's downlink control information, which will be transmitted to the terminal, in the corresponding position in the same downlink control signaling, and then transmits the signaling to the terminal; the BS inserts the determined dedicated pilot of each data flow into the corresponding data flow, and then transmits the data flow to the terminal; according to the determined position of each data flow's downlink control information in the same downlink control signaling, the terminal determines each data flow's downlink control information in the downlink control signaling; and the terminal receives multiple data flows transmitted from the BS, identifies each data flow by utilizing the determined dedicated pilot of each data flow, decodes the corresponding data flow based on each data flow's downlink control information, and thereby obtains the service data carried in each data flow. |
