    • A Hybrid Automatic Repeat reQuest (HARQ) control apparatus and method for detecting a message received over a packet data control channel in a mobile communication system are provided in which a base station transmits a packet data control message over at least one packet data control channel and transmits packet data to a mobile station over a packet data channel. A control channel decoder decodes a control message received over the packet data control channel. Based on the decoded control message, the HARQ controller determines at least one of whether to perform demodulation and decoding on a packet received over the packet data channel, whether to update a Walsh mask, and whether to perform state transition on the mobile station. The HARQ controller based on the determination performs at least one of the following functions: outputs demodulation and decoding parameters, updates a Walsh mask, and outputs a state transition value to an upper layer. A data channel demodulator demodulates packet data received over the packet data channel upon receiving a demodulation parameter from the HARQ controller.

    • A method and apparatus for effectively controlling data input to a turbo decoder for decoding forward packet data traffic in a 1xEV-DV mobile station (MS) are disclosed. After received code symbols are stored in one of several memories and read in deinterleaving order, read addresses and chip select signals are generated for the memories based on encoder packet size in synchronization to a decoder clock signal. The decoding starts by inputting a predetermined number of code symbols to the turbo decoder in an appropriate order. The decoder input apparatus reads demodulated forward packet data from decoder input buffers in an appropriate order using the read addresses and chip select signals to generate turbo decoder input data in an appropriate form. Thus, a small-size, low-cost, low-power consumption MS is achieved by processing channel-interleaved data at high speed and with reduced process delay and providing them to a decoder.

    • A method and apparatus for determining an optimum modulation scheme for a retransmission in a communication system supporting HARQ. When two modulation schemes are available, at an initial transmission, information is modulated in the lower-order modulation scheme if a first MPR is less than a first threshold, and in the higher-order modulation scheme if the first MPR is greater than or equal to the first threshold. Here, an MPR is determined by an EP size, the number of available Walsh codes, and the number of slots per sub-packet that are used for a transmission. To select one of the modulation schemes for a retransmission, a second MPR is calculated using an EP size, the number of available Walsh codes, and the number of slots per sub-packet that are used for the retransmission. If the first MPR is equal to or less than a second threshold greater than the first threshold, the lower-order modulation scheme is selected. If the second MPR is greater than the second threshold, the higher-order modulation scheme is selected.
