6. A method of obtaining buffer status information of a user equipment at a base station in an orthogonal frequency division multiplexing (OFDM)-based mobile communication system, wherein the user equipment is in a state that data transmission from the user equipment is performed based on scheduling from the base station, the method comprising:
receiving, by the base station, a signal of one bit-level information from the user equipment periodically via a physical uplink channel that is not a random access channel, while there is no traffic channel resource from the user equipment to the base station, wherein the signal is for informing presence of a request for an uplink channel resource used to communicate the buffer status information to the base station;
transmitting, by the base station, first resource allocation information for a first uplink channel to the user equipment after receiving the signal; and
receiving, by the base station, the buffer status information from the user equipment through the first uplink channel using the first resource allocation information.
