Title
(EN) RATE-MATCHING SCHEME FOR CONTROL CHANNELS USING POLAR CODES
(FR) SCHÉMA D'ADAPTATION DE DÉBIT POUR CANAUX DE COMMANDE UTILISANT DES CODES POLAIRES
Abstract
(EN)
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching control channels using polar codes. An exemplary method generally includes encoding a stream of bits using a polar code, determining a size of a circular buffer for storing the encoded stream of bits based, at least in part, on a minimum supported code rate and a control information size, and performing rate-matching on stored encoded stream of bits based, at least in part, on a final coded block size of the stored encoded stream of bits, J, and an allocated coded block size, M.

Certains aspects de la présente invention concernent d'une façon générale des communications sans fil et, plus particulièrement, des procédés et un appareil d'adaptation de débit pour des canaux de commande utilisant des codes polaires. Un procédé donné à titre d'exemple de l'invention consiste d'une manière générale à : coder un flux de bits à l'aide d'un code polaire ; déterminer une taille d'un tampon circulaire pour stocker le flux codé de bits sur la base, au moins en partie, d'un débit de code minimum pris en charge et d'une taille d'informations de commande ; et exécuter une adaptation de débit sur un flux codé et stocké de bits sur la base, au moins en partie, d'une taille de bloc codé final du flux codé et stocké de bits (J), et d'une taille de bloc codé attribuée (M).
