Title (EN) POLAR CODES FOR DOWNLINK CONTROL CHANNELS FOR WIRELESS NETWORKS
(FR) CODES POLAIRES POUR CANAUX DE COMMANDE DE LIAISON DESCENDANTE DE RÉSEAUX SANS FIL
Abstract:
(EN) Polar Codes for Downlink Control Channels for Wireless Networks A technique is provided for decoding downlink control information that was encoded using polar encoding, the technique including: attempting, based on an initial assumption by a user device of a segmented downlink control information, to decode a first codeword provided via a user device-specific resource, the first codeword including a first downlink control information segment and a pointer to a second downlink control information segment of a segmented downlink control information; decoding, if the attempting to decode is successful, based on the pointer, a second codeword that includes the second downlink control information segment of the segmented downlink control information; and otherwise, if the attempting to decode is unsuccessful, making an assumption of a non- segmented downlink control information and decoding a third codeword to obtain a non- segmented downlink control information.
(FR) Une technique est fournie afin de décoder des informations de commande de liaison descendante qui ont été codées à l'aide d'un codage polaire, la technique comprenant : la tentative, sur la base d'une supposition initiale par un dispositif utilisateur d'une information de commande de liaison descendante segmentée, de décoder un premier mot de code fourni par l'intermédiaire d'une ressource spécifique à un dispositif utilisateur, le premier mot de code comprenant un premier segment d'informations de commande de liaison descendante et un pointeur vers un second segment d'informations de commande de liaison descendante d'informations de commande de liaison descendante segmentées ; le décodage, si la tentative de décodage est réussie et sur la base du pointeur, d'un second mot de code qui comprend le second segment d'informations de commande de liaison descendante des informations de commande de liaison descendante segmentées ; et sinon, si la tentative de décodage échoue, la réalisation d'une supposition d'informations de commande de liaison descendante non segmentées et le décodage d'un troisième mot de code pour obtenir des informations de commande de liaison descendante non segmentées.
