An apparatus and method are provided for determining a data rate by means of control information in a mobile communication system which includes a User Equipment (UE) and a Node B. The UE transmits data to the Node B, and the Node B transmits the control information to the UE. The data rate is determined by means of the control information and is used for transmission of the data by the UE. The apparatus and method comprise determining a preliminary data rate in consideration of a quantity of data waiting for transmission; comparing the preliminary data rate with a previous data rate used for previous data transmission; and determining the data rate according to a result of comparison so that the UE can transmit the data at the data rate.

Apparatus and method for data rate scheduling of user equipment in a mobile communication system

A method and apparatus for performing channel compensating in a mobile communication terminal calculates a channel prediction value by varying an energy cumulative interval based on channel variation occurring in a radio channel. In accordance with one illustrative embodiment, the energy cumulative interval is varied from a minimum 2T to a maximum 6T according to a traveling speed of a terminal. As a result of this compensation, channel prediction error is reduced. And accordingly more accurate channel compensation is performed.
