Title (EN) CONSTRUCTION OF CHANNEL ORDERING FOR POLAR CODE
(FR) CONSTRUCTION D'UN ORDRE DE CANAL POUR CODE POLAIRE
Abstract:
(EN) A wireless device (e.g., a base station or user equipment (UE)) may encode a codeword using a polar code for transmission over a wireless channel. The device may identify a set of bit locations of the polar code for a set of information bits based on a bit index reliability sequence. The bit index reliability sequence may be based on applying an ordered combination of a universal partial order, an analytical method, and a simulation. The bit index reliability sequence may be determined based on a binary bit weighting for the set of bit channels that applies one or more weighting factors. In some cases, the device may store the bit index reliability sequence in a lookup table for encoding, decoding, or both. A device receiving the transmitted codeword may similarly utilize the bit index reliability sequence to decode the codeword and determine the transmitted information bits.
(FR) La présente invention concerne un dispositif sans fil (par ex., une station de base ou un équipement utilisateur (UE)) permettant de coder un mot de code à l'aide d'un code polaire pour une transmission sur un canal sans fil. Le dispositif peut identifier un ensemble d'emplacements de bits du code polaire pour un ensemble de bits d'informations sur la base d'une séquence de fiabilité d'index de bit. La séquence de fiabilité d'index de bit peut être basée sur l'application d'une combinaison ordonnée d'un ordre partiel universel, d'un procédé analytique et d'une simulation. La séquence de fiabilité d'index de bit peut être déterminée sur la base d'une pondération de bit binaire pour l'ensemble de canaux de bits qui applique un ou plusieurs facteurs de pondération. Dans certains cas, le dispositif peut stocker la séquence de fiabilité d'index de bit dans une table de consultation pour le codage et/ou le décodage. Un dispositif recevant le mot de code transmis peut également utiliser la séquence de fiabilité d'index de bit pour décoder le mot de code et déterminer les bits d'informations transmis.
