Abstract

MÉTODO PARA A TRANSMISSçO SEGURA DE BITMAPS DE ACK/NACK CURTOS EM PROCESSO ARQ DENTRO DE SISTEMAS EM CONFORMIDADE COM EDGE. A presente invenção refere-se a um aperfeiçoamento às propostas mais recentes sobre um mecanismo ARQ rápido a ser operado logo dentro dos sistemas de rádio móveis GERAN 3GPP. O ARQ rápido avalia os bitmaps curtos, abrangendo apenas poucos octetos, piggybacked na carga útil do bloco MAC/RLC que porta a sinalização ACK/NACK relevante. O aperfeiçoamento principal é que para se mudar o bitmap curto a partir dos dados de carga útil para o cabeçalho do mesmo bloco MAC/RLC transmitido na direção de uplink ou downlink, indiferentemente. Isso permite que o bitmap curto seja codificado juntamente com o cabeçalho, levando vantagem da mesma codificação que é perceptivelmente mais robusta do que a utilizada para a carga útil. A sincronização entre os quadros de transmissão e recepção é solicitada no reporte com bitmaps curtos. A retransmissão corrigida de blocos de rádio recebidos de forma ruim precisa do conhecimento do retardo fixo (expresso como um número de períodos de bloco MAC/RLC) entre o momento de transmissão de um bloco de rádio e o momento de recepção do bitmap curto. Um segundo aperfeiçoamento é alocar o bitmap curto em uma nova zona localizada imediatamente depois do cabeçalho dos blocos MAC/RLC, e codificar os mesmos independentemente da carga útil utilizando uma codificação mais robusta contra os erros do que a robustez do MCS utilizado na parte de dados de carga útil.
