  • Publication number: 20170208610
    Abstract: The present invention discloses a data transmission method and device. When user equipment needs to send uplink data to a base station device, but the base station has not triggered uplink scheduling for the to-be-sent data of the user equipment, a first solution is proposed: Control information is sent by using an uplink transmission resource, then uplink scheduling information is obtained from the base station, and the uplink data is sent to the base station by using the uplink scheduling information. A second solution is also proposed: The uplink data is sent to the base station by using common uplink scheduling information configured by the base station. The two solutions simplify a procedure for uplink data transmission between the user equipment and the base station, so that a data transmission delay is reduced, and system performance is improved.
