    摘要： Provided are an apparatus and method for managing connection identifiers (CIDs) in a multi-hop relay Broadband Wireless Access (BWA) system. An apparatus is provided for a Relay Station (RS) in a multi-hop relay cellular communication system. The apparatus includes a database, a controller, and a transmitter. The database is used for managing a Connection Identifier (CID) set assigned to the RS by a Base Station (BS). The controller accesses the database to assign one CID of the CID set to a Mobile Station (MS) when receiving a control message from the MS. The transmitter constructs a response message including the CID assigned to the MS and transmits the response message to the MS. The MS can be assigned a CID directly from the RS in a condition that the BS is not involved, so that the initial ranging procedure can be rapidly performed.

    摘要： An apparatus and method for transmitting a signal in a communication system using a Hybrid Automatic Repeat reQuest (HARQ) scheme are provided. The method includes generating a codeword vector by encoding an information vector by using a first parity check matrix of Low Density Parity Check (LDPC) codes, generating a transmission vector by processing the codeword vector, and transmitting the transmission vector. When the first parity check matrix includes a plurality of square matrix columns, each square matrix includes a size of L × L , the first parity check matrix is one of p parity check matrixes stored in the signal transmission apparatus, the p parity check matrixes support different numbers of information vector square matrix columns, and each of the numbers of information vector square matrix columns indicates the number of square matrix columns corresponding to the information vector from among the plurality of square matrix columns. The first parity check matrix is a parity check matrix supporting the number of information vector square matrix columns determined by using the length of the information vector and the value L from the p parity check matrixes, and the value L is determined by using p and the length of the information vector.
