Disclosed is a method of setting a data transmission rate capable of setting data transmission rate of a data packet received from an upper node in mobile communication system based on a wireless environment and retransmission rate. The preferred embodiment provides not only a method to check data flow to optimize the method of assigning and withdrawing wireless channels assigned to the mobile station, but also a method of assigning and withdrawing wireless channels by checking a wireless environment and a data flow at the same time using NAK frame affected by wireless environment. It is thus possible to quickly determine the influence from a wireless environment that frequently varies and to control a data transmission rate while ensuring the mobility of the database.
