Abstract: A data transmission method, comprising: receiving first downlink control information related to uplink transmission; acquiring uplink and downlink transmission region indication information; according to the received first downlink control information and the acquired uplink and downlink transmission region indication information, conducting uplink transmission in an uplink transmission region of a sub-frame n; and conducting downlink reception in a downlink transmission of the sub-frame n, where n is an integer. By means of the solution, a pre-scheduled sub-frame for uplink transmission also comprises a downlink transmission region for downlink transmission. When downlink transmission needs to be conducted, a downlink service can be transmitted in time through the downlink transmission region. Based on the existing LTE frame, a low time delay data transmission solution is implemented, so that a service with a low time delay requirement can be satisfied.
