Title
(EN) DOWNLINK CONTROL INFORMATION SIZE CONFIGURATION IN CROSS-CARRIER SCHEDULING SCENARIOS
(FR) CONFIGURATION DE TAILLE D'INFORMATIONS DE COMMANDE DE LIAISON DESCENDANTE DANS DES SCÉNARIOS DE PLANIFICATION INTER-PORTEUSE
Abstract
(EN) Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a secondary cell and a primary cell where cross-carrier scheduling is to occur from the secondary cell to the primary cell, whether a quantity of downlink control information (DCI) sizes for a set of DCIs that the UE monitors satisfies a threshold, wherein the threshold is a per scheduling cell per scheduled cell threshold or a per scheduled cell threshold. The UE may selectively perform a DCI size alignment procedure to adjust a DCI size configuration based at least in part on whether the quantity of DCI sizes satisfies the threshold. The UE may monitor for the set of DCIs based at least in part on the DCI size configuration. Numerous other aspects are provided.
(FR) Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut déterminer, pour une cellule secondaire et une cellule primaire où une planification inter-porteuse doit se produire de la cellule secondaire à la cellule primaire, si une quantité de tailles d'informations de commande de liaison descendante (DCI) pour un ensemble de DCI que l'UE surveille satisfont un seuil, le seuil étant une cellule par programmation par cellule de programmation par seuil de cellule programmée ou un seuil de cellule programmé. L'UE peut réaliser sélectivement une procédure d'alignement de taille de DCI pour régler une configuration de taille de DCI sur la base, au moins en partie, du fait que la quantité de tailles de DCI satisfait le seuil. L'UE peut surveiller l'ensemble de DCI sur la base, au moins en partie, de la configuration de taille de DCI. La divulgation concerne également de nombreux autres aspects.
