Abstract

"ESQUEMA DE CODIFICAçãO EM BLOCOS DE DISTâNCIA MáXIMA". Em um sistema de comunicação de dados capaz de transmissão a taxas variáveis, a transmissão de dados de pacote a uma taxa elevada melhora a utilização do link direto e diminui o retardo de transmissão. A transmissão de dados no link direto é multiplexado no tempo e a estação base (4) transmite à taxa de dados mais elevada suportada pelo link direto em cada time slot para uma estação móvel (6). A taxa de dados é determinada pela maior medição de C/I dos sinais de link direto, conforme medida na estação móvel (6). Quando se determina que um pacote de dados foi recebido com erro, a estação móvel (6) transmite uma mensagem NACK de volta à estação base (4). A mensagem NACK resulta na retransmissão do pacote de dados recebido com erro. Os pacotes de dados podem ser transmitidos fora de seq³ência pelo emprego do número de seq³ência, de modo a se identificar cada unidade de dados dentro dos pacotes de dados. No link reverso, os símbolos indicadores de taxa reversa são codificados na estação móvel (6) de modo a se obter uma distância máxima entre diferentes palavras de código."CODING SCHEME IN MAXIMUM DISTANCE BLOCKS". In a data communication system capable of variable rate transmission, high rate packet data transmission improves direct link utilization and decreases transmission delay. Forward link data transmission is time multiplexed and base station (4) transmits at the highest data rate supported by the forward link in each time slot to a mobile station (6). The data rate is determined by the highest C / I measurement of direct link signals as measured at the mobile station (6). When it is determined that a data packet has been received in error, the mobile station (6) transmits a NACK message back to the base station (4). The NACK message results in retransmission of the received data packet in error. Data packets may be transmitted out of sequence by employing the sequence number to identify each data unit within the data packets. In reverse link, reverse rate indicator symbols are encoded in mobile station (6) to obtain a maximum distance between different codewords.
