    Abstract: A method for transmitting data within a communication system (100) comprises determining a carrier bandwidth from a set of two or more carrier bandwidths, receiving data to be transmitted over a radio frame (300, 400, 500), wherein the radio frame is comprised of a plurality of subframes (301, 401, 501), and placing data within a subframe in the radio frame to produce a subframe of data. The subframe of data comprises either a plurality of OFDM symbols or a plurality of single carrier FDMA symbols, at least two of the OFDM symbols or at least two of the single carrier FDMA symbols in the subframe having different symbol durations. The radio frame and subframe have the same duration for each of the carrier bandwidths in the set of two or more carrier bandwidths. The OFDM symbols or single carrier FDMA symbols in the subframe comprise a plurality of subcarriers and wherein the plurality of symbols and subcarriers in the subframe are grouped into resource blocks such that the carrier bandwidth is divided into an integer number of resource blocks. The at least two OFDM or single carrier FDMA symbols in each of the plurality of subframes differ in cyclic prefix duration by one sample duration corresponding to the smallest carrier bandwidth in the set of two or more carrier bandwidths. The subframe of data is transmitted over the radio frame and in the determined carrier bandwidth. A mobile station or a base station adapted to perform the steps of the method for transmitting data is also disclosed and claimed.

    IPC: H03M13/00

    Abstract: Aquí se provee un método y aparato de turbo codificacion con un intercalador sin contencion. Durante la operacion, se recibe un bloque de entrada de tamano K. El bloque de entrada original y el bloque de entrada intercalado se codifican para obtenerun bloque de palabra codigo, donde el bloque de entrada original se intercala usando un intercalador de tamano K y una permutacion, donde 0 i K-1 es el índice secuencial de las posiciones de símbolo después del intercalado, (i) es el índice desímbolos antes del intercalado correspondiente a la posicion i, K es el tamano del intercalador de símbolos, y f1 y f2 son los factores que definen el intercalador. Los valores de K, f1, f2 se toman de por lo menos una fila de una tabla. El bloquede palabra codigo se transmite por el canal.

    IPC: H03M13/03

    Abstract: A method and apparatus for performing H-ARQ transmission is described herein. Bits received on a first transmission are stored and combined with the bits received on later transmissions thereby increasing the likelihood of a correct decoding on later transmissions. Additionally, a plurality of coding schemes (e.g., Convolutional Codes, Block Turbo Codes, Convolutional Turbo Codes, Low Density Party Check Codes, . . . , etc.) are utilized, with an information element being reserved to signal what form of H-ARQ is being utilized.

    IPC: H03M13/03

    Abstract: En la presente se describen un metodo y un aparato para realizar la transmision de H-ARQ. Los bits recibidos en una primera transmision se almacenan y combinan con los bits recibidos en transmisiones posteriores incrementando consecuentemente la probabilidad de una decodificacion correcta en transmisiones posteriores. Ademas, se utiliza una pluralidad de esquemas de codificacion (por ejemplo, Codigos de Convolucion, Turbo Codigos de Bloque, Turbo Codigos de Convolucion, Codigos de Verificacion de Paridad de Baja Densidad, ..., etc.), con un elemento de informacion que se reserva para senalizar cual forma de H-ARQ se utiliza.

    Abstract: A method in a communication system (100) includes transmitting from a source user (101) a first data packet (111) over a first time frame (121) having a finite time period (131), transmitting from source user (101) a second data packet (112) over a second time frame (122) immediately subsequent to first time frame (121), detecting an acknowledgment of acceptable reception of data packet associated with either first or said second data packets (111 and 112), repeating transmission of first and second data packets (111 and 112) in a sequence of first and second time frames (121 and 122) in a time frame sequence (190) until the detection.
