Method for determining transmission time interval, base station, and radio network controller

A method for indicating a transmission time interval, comprising:

• receiving, by a base station, uplink data sent from a user equipment in an idle state or a cell forward access channel state on an enhanced dedicated transmission channel;
• determining, by the base station, a transmission time interval used by the user equipment for sending the uplink data;
• and
• sending, by the base station, the uplink data in an enhanced dedicated transmission channel data frame to a radio network controller through a transmission bearer corresponding to the transmission time interval, so that the radio network controller determines, according to the transmission bearer, the transmission time interval used by the user equipment for sending the uplink data.

A base station, comprising:

• a receiver, configured to receive uplink data sent from a user equipment in an idle state or a cell forward access channel state on an enhanced dedicated transmission channel;
• a processor, configured to determine a transmission time interval used by the user equipment for sending the uplink data;
• and
• a transmitter, configured to send the uplink data in an enhanced dedicated transmission channel data frame to a radio network controller, wherein the enhanced dedicated transmission channel data frame carries a transmission time interval indicator indicating to the radio network controller the transmission time interval used by the user equipment for sending the uplink data.
