摘要： 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 decoder decodes the packet data demodulated by the data channel demodulator upon receiving a decoding parameter from the HARQ controller.

摘要： Disclosed is an apparatus and method for supporting automatic repeat request (ARQ) in a high-speed wireless packet data communication system. A mobile station receives control information including a subpacket identifier (SP_ID) representing the sequence of a subpacket, the size of an encoder packet (EP_SIZE), and a sequence identifier (AI_SN) that is toggled each time a new encoder packet is transmitted, while receiving one of a plurality of subpackets generated by segmenting a bit stream acquired by encoding a transmission encoder packet. The mobile station determines whether it will perform a decoding process caused by initial transmission or a decoding process caused by retransmission on the received subpacket, based on the control information.

摘要： Disclosed is a 16-ary QAM (Quadrature Amplitude Modulation) demodulation apparatus for receiving an input signal Rk(Xk, Yk) comprised of a kth quadrature-phase component Yk and a kth in-phase component Xk, and generating soft values &Lgr;(sk,0), &Lgr;(sk,1), &Lgr;(sk,2) and &Lgr;(sk,3) for the input signal Rk(Xk, Yk) by a soft decision means. A first calculator decides a soft value &Lgr;(sk,2) of a third demodulated symbol among 4 demodulated symbols by subtracting a distance 2a between two demodulated symbols on the same axis of a mapping table from a level |Yk| of the quadrature-phase component Yk. A second calculator decides a soft value &Lgr;(sk,3) of a fourth demodulated symbol by calculating Yk+&agr;*Zk using a first variable a determined by the soft value of the third demodulated symbol and a sign bit of the quadrature-phase component Yk. A third calculator decides a soft value &Lgr;(sk,0) of a first demodulated symbol by subtracting the distance 2a from a level |Xk| of the in-phase component Xk. A fourth calculator decides a soft value &Lgr;(sk,1) of a second demodulated symbol by calculating Xk+&bgr;*Z′k using a second variable &bgr; determined by the soft value of the first demodulated symbol and a sign bit of the in-phase component Xk.

摘要： 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.
