Title (EN) ADAPTIVE TWO-STAGE DOWNLINK CONTROL CHANNEL STRUCTURE FOR CODE BLOCK GROUP BASED FIFTH GENERATION (5G) OR OTHER NEXT GENERATION SYSTEMS
(FR) STRUCTURE DE CANAL DE COMMANDE DE LIAISON DESCENDANTE ADAPTATIF À DEUX ÉTAGES POUR SYSTÈMES DE CINQUIÈME GÉNÉRATION (5G) OU D'AUTRES GÉNÉRATIONS PROCHAINES BASÉS SUR DES GROUPES DE BLOCS DE CODE
Abstract:
(EN) An adaptive two-stage downlink control channel structure is utilized for control channel transmission with code block group (CBG) retransmission for 5G and other next generation wireless systems. In an aspect, the first stage of the two-stage downlink control channel structure utilizes a defined format (e.g., having a fixed length) and provides information that is employable to determine the length and/or coding scheme of the second stage. In another aspect, the second stage of the two-stage downlink control channel structure utilizes a variable length/size to indicate the CBGs that are scheduled to be retransmitted (e.g., by employing a variable length bitmap). As an example, the length/size is varied based on a length/size of a transport block, from which the CBGs have been generated.
(FR) La présente invention concerne une structure de canal de commande de liaison descendante adaptatif à deux étages qui est utilisée pour la transmission de canal de commande avec retransmission de groupes de blocs de code (CBG) pour des systèmes sans fil 5G et d'autres générations prochaines. Selon un aspect, le premier étage de la structure de canal de commande de liaison descendante à deux étages utilise un format défini (p. ex. de longueur fixe) et fournit des informations qui peuvent être employées pour déterminer la longueur et/ou le schéma de codage du second étage. Selon un autre aspect, le second étage de la structure de canal de commande de liaison descendante à deux étages utilise une longueur/taille variable pour indiquer les CBG dont la retransmission est programmée (p. ex. en employant un bitmap de longueur variable). À titre d'exemple, la longueur/taille fait l'objet d'une variation en fonction d'une longueur/taille d'un bloc de transport à partir duquel les CBG ont été générés.
