The present disclosure discloses a method and a device for data transmission, a computer program and a storage medium, and belongs to the field of mobile communication technology. The method includes: determining the configuration information of at least one flexible subframe included by a time division multiplexing TDD wireless frame, and the flexible subframe is configured to contain at least one uplink transmission symbol and at least one downlink transmission symbol, and alternate configuration of sub time slots used by uplink transmission symbols and downlink transmission symbols; The configuration information of at least one flexible subframe is sent to the user's device UE by signaling; the uplink data is received in the sub slot of the uplink transmission symbol in accordance with the configuration information of the at least one flexible subframe, and the downlink data is sent in the subslot of the downlink transmission symbol. The disclosure of uplink transmission symbols and downlink transmission symbols can be realized in the same flexible subframe, so that the feedback of the confirmation message of the user equipment can be quickly carried out, the transmission delay is reduced, and the service transmission needs of various low time delay requirements of TDD are satisfied.
