    摘要: A method for supporting short latency data transmission in a mobile communication system is provided. A frame is divided into an uplink subframe and a downlink subframe. Each of the uplink and downlink subframes includes at least one zone for the short latency data transmission and each of the at least one zone includes a first channel for indicating data resource assignment, a second channel over which to transmit data, or a third channel for feedback signal reception. The method includes indicating a location and a size of the second channel using the first channel included in any one of the at least one zone by a transmitting end, transmitting data over the second channel, and receiving feedback information for the data, which has been transmitted over the second channel, over the third channel.

    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.
