Abstract

diversos aspectos da revelação referem-se à codificação de informação e decodificação de informação. sob alguns aspectos, a revelação refere-se a um codificador e um decodificador para códigos polares com harq. se uma primeira transmissão do codificador falhar, os bits de informação associados a um canal de qualidade inferior podem ser retransmitidos. no decodificador, os bits retransmitidos decodificados resultantes podem ser utilizados para decodificar a primeira transmissão, substituindo os bits retransmitidos pelos bits correspondentes originais (canal de baixa qualidade). sob alguns aspectos, para decodificar a primeira transmissão, a combinação flexível é aplicada aos bits retransmitidos decodificados e aos bits correspondentes originais (canal de baixa qualidade). sob alguns aspectos, os bits crc para uma primeira transmissão podem ser divididos entre um primeiro subconjunto de bits e um segundo subconjunto de bits. neste caso, o segundo subconjunto de bits e os bits de crc associados podem ser utilizados para uma segunda transmissão (como, por exemplo, uma retransmissão).
