Embodiments of the present invention provide a method for determining a transmission time interval, a base station, and a radio network controller. The method for determining a transmission time interval includes: receiving, by a base station, uplink data sent by a user equipment in idle state or Cell-FACH state on an E-DCH; determining, by the base station, a TTI used by the user equipment for sending the uplink data; and carrying, by the base station, the uplink data in an E-DCH data frame, and sending the E-DCH data frame to a radio network controller, where the E-DCH data frame carries a TTI indicator, so as to notify the radio network controller of the TTI used by the user equipment for sending the uplink data. The embodiments of the present invention may implement that the radio network controller acquires the TTI used by the user equipment in idle state or Cell-FACH state when sending the uplink data, thereby ensuring that the radio network controller selects and configures an appropriate TTI for the user equipment when the user equipment transits from the Cell_FACH state to the Cell_DCH state. |
