Title
(EN) CODEWORD BIT SELECTION FOR RATE-COMPATIBLE POLAR CODING
(FR) SÉLECTION D'ÉLÉMENT BINAIRE DE MOT DE CODE DESTINÉE À UN CODAGE POLAIRE COMPATIBLE AVEC LE DÉBIT
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an encoding device may determine a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded; may determine a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits; may add the codeword bit to the codeword; and may transmit the codeword. Numerous other aspects are provided.
(FR)
Divers aspects de la présente invention concernent de façon générale la communication sans fil. Selon certains aspects, un dispositif de codage peut déterminer un sous-ensemble moins fiable d'éléments binaires d'informations compris dans un ensemble d'éléments binaires d'informations qui comprend un ensemble actif prédéfini d'éléments binaires d'informations à coder; peut déterminer un élément binaire de mot de code à ajouter à un mot de code sur la base, au moins en partie, du sous-ensemble moins fiable d'élément binaire d'informations, l'ajout de l'élément binaire de mot de code au mot de code améliore la fiabilité du sous-ensemble moins fiable d'éléments binaires d'informations; peut ajouter l'élément binaire de mot de code au mot de code; et peut transmettre le mot de code. L'invention concerne également de nombreux autres aspects.
