Abstract:
1. A method of determining a data rate for traffic data to be transmitted from a mobile station to a base station in a mobile communication system, the method comprising: transmitting control information to the base station, the control information corresponding to the traffic data of an ith frame, the ith frame having a predetermined data rate; receiving, in response to the transmitted control information, data rate control information from the base station, the data rate control information including an instruction which indicates one of an n-step increment of data rate, an m-step decrement of data rate, or a hold of data rate, where n and m are integers greater than or equal to one; and determining a data rate of traffic data to be transmitted from the mobile station to the base station during an (i+β)th frame, by applying the instruction included in the data rate control information to the predetermined data rate of the ith frame, wherein β is an integer greater than one, wherein ith frame is a non-consecutive preceding frame relative to the (i+β) frame and wherein the n-step increment, m-step increment, or hold of data rate indicated by the instruction is applied relative to the data rate of the ith frame.
