Abstract[English]
Methods and apparatuses for performing a set of transmissions using polar coding with retransmissions using cross-block check blocks are described. A first transmission is performed at a first code rate, the first transmission including a first plurality of information blocks, each information block having a plurality of information bits. A second transmission is performed at a second code rate that is lower than the first code rate. The second transmission includes a set of cross-block check blocks generated using information bits selected from across a second plurality of information blocks. Each of the second plurality of information blocks is a subset of the information bits of a respective one of the first plurality of information blocks, the information bits of each subset being selected from least reliable bit channels of the respective one of the plurality of information blocks.[French]
L'invention concerne des procédés et des appareils destinés à établir un ensemble de transmissions à l'aide d'un codage polaire avec des retransmissions à l'aide de blocs de contrôle inter-blocs. Une première transmission est établie à un premier débit de code, la première transmission comprenant une première pluralité de blocs d'informations, chaque bloc d'informations contenant une pluralité de bits d'informations. Une seconde transmission est établie à un second débit de code qui est inférieur au premier débit de code. La seconde transmission comprend un ensemble de blocs de contrôle inter-blocs générés à l'aide de bits d'informations sélectionnés parmi une seconde pluralité de blocs d'informations. Chacun de la seconde pluralité de blocs d'informations est un sous-ensemble des bits d'informations d'un bloc respectif de la première pluralité de blocs d'informations, les bits d'informations de chaque sous-ensemble étant sélectionnés parmi des canaux de bits les moins fiables du bloc respectif de la pluralité de blocs d'informations.
