Abstract

a presente invenção refere-se a aspectos que proporcionam uma técnica para implementar a codificação polar com retransmissão de harq de redundância incremental. em particular, um transmissor pode codificar uma mensagem utilizando diferentes códigos polares para obter uma primeira palavra código e uma segunda palavra código que é duas vezes o comprimento da primeira palavra código, e transmitir a primeira palavra código como uma transmissão original, e a segunda metade da segunda palavra código como uma retransmissão sem transmitir a primeira metade da segunda palavra código. bits de informação que são comuns tanto à primeira palavra código como a segunda metade da segunda palavra código podem ser mapeados para localizações de bits mais confiáveis na segunda metade da segunda palavra código. os valores de bits decodificados para a informação comum na transmissão e retransmissão originais podem ser comparados pelo receptor para a realização de uma verificação de paridade.
