Abstract: A system and method for the state synchronization between a base station and a mobile station in a BWA(Broadband Wireless Access) communication system are provided to enable an MS(Mobile Station) to match state synchronization with a BS(Base Station) as the BS, in case that the CPU is reset, sends a changed reset count value to the MS and the MS executes network re-entry procedures after comparing the present reset count value with the previous reset count value. A base station periodically transmits a downlink frame containing DLFP(Downlink Frame Prefix) information to an MS(702,704). Whenever DLFP information is received, the MS extracts a reset count value and compares the extracted present reset value with a previously stored old reset count value(706). If a CPU of the BS is reset(708), the BS increases the reset count value by 1(710). Then, the BS transmits DLFP information containing the increased reset count value to the MS(712). At this time, the MS compares the present reset count value contained in the received DLFP information with a previously stored old reset count value(714). If it is judged that the two values are different, the MS, recognizing that the CPU of the BS has been reset, executes network re-entry procedures for state synchronization with the BS(716).

Abstract: A method and an apparatus for transmitting and receiving a signal in a communication system using an HARQ(Hybrid Automatic Repeat request) method are provided to transmit and receive a signal using various coding rates. A signal transmission apparatus includes an encoder(311), a modulator(313), and a transmitter(315). The encoder generates the codeword vector by encoding an information vector using a first parity check matrix of an LDPC(Low Density Parity Check) code. A modulator generates a codeword vector to a modulation vector using a modulation method and outputs the modulation vector to the transmitter. The transmitter processes the codeword vector and transmits the transmission vector after generating the transmission vector. A first parity check matrix includes a plurality of square matrix rows. The first parity check matrix is one among the p parity check matrixes stored in the signal transmission apparatus. The p parity check matrixes support the number of the different information vector square matrix rows respectively.
