Abstract

aspectos da presente descrição se referem a retransmissões de dados dentro das redes de comunicação sem fio. para uma retransmissão, pelo menos uma parte dos bits codificados de uma transmissão original pode ser mapeada em diferentes localizações de bit em um ou mais símbolos modulados com base em uma regra de mapeamento não randômico. em alguns exemplos, os bits codificados de um símbolo podem ser invertidos dentro do símbolo para uma retransmissão. em outros exemplos, os primeiro e último bits codificados dentro de um símbolo podem ser comutados para uma retransmissão. outras regras de mapeamento não randômico, tal como um desvio de localização de bit, também podem ser utilizadas para mapear os bits codificados em diferentes localizações de bit no símbolo modulado dentro de uma retransmissão.
