Abstract: 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.

Abstract: An apparatus and method for detecting the reception timing of a received signal in a mobile communication system are provided. Two time points having the same energy, earlier and later than the received signal, are detected. The energy ratio between other time points spaced from the two time points by the same interval is calculated and it is determined whether the energy ratio falls into a predetermined rage. If the energy ratio is within the range, the received signal is considered to have no effects from an interference signal or a neighboring signal.

Abstract: 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.

Abstract: Disclosed are an apparatus and a method capable of preventing performance degradation during a channel decoding process. A bit interleaving is performed with respect to parity bits among coded bits output through a channel coding unit, thereby preventing a repetition period of the parity bits from matching a puncturing period for a rate matching. A bit de-interleaving is performed with respect to the parity bits during a channel decoding process, so that the parity bits have a repetition period identical to initial parity bits. Thus, the repetition period of the parity bits is not matched with the puncturing period for the rate matching, thereby preventing performance degradation during the channel decoding process.
